Changelog from 2.6.12-rc3 to 2.6.12-rc4 ======================================= Al Viro : [SPARC64]: sparc64 preempt + smp PREEMPT+SMP support - see if it looks sane... Signed-off-by: Al Viro Signed-off-by: David S. Miller James Bottomley : [PATCH] Fix aic7xxx_osm.c compile with older gcc's My version of gcc doesn't warn about this error (declaration in the middle of a set of statements). The fix is simple (this also corrects return code; for init functions it should be zero or error). Alexander Nyberg : [PATCH] x86_64: Bug in new out of line put_user() The new out of line put_user() assembly on x86_64 changes %rcx without telling GCC about it causing things like: http://bugme.osdl.org/show_bug.cgi?id=4515 See to it that %rcx is not changed (made it consistent with get_user()).

Signed-off-by: Karsten Keil Signed-off-by: Linus Torvalds David Mosberger-Tang : [IA64] fix fls() The ia64-version of fls() never worked as intended (the bitnumbering was off by 1 and fls(0) was undefined). This patch fixes the problem by using a popcnt-based fls(), which on McKinley-derived cores is slightly faster than both ia64_fls() and generic_fls(). The resulting code, however, is bigger (7-8 bundles instead of about 3 bundles). Also switch ia64_popcnt() to __builtin_popcountl() for GCC v3.4 or newer since the compiler can predicate that and schedule it better. Thanks to Simon Derr and Matt Mackall for tracking down this bug.

Signed-off-by: Stefan Richter Signed-off-by: Jody McIntyre Signed-off-by: Linus Torvalds Jody McIntyre : [PATCH] Fix non-legacy ISO receive regression Fix non-legacy multichannel ISO receive, broken by Parag Wardukar's allocation fix. Multichannel ISO receive still sucks; it should be possible to use both legacy and non-legacy modes at the same time, but with this patch, things are no worse than they were in 2.6.11 and allocation is still done at the correct time. Signed-off-by: Jody McIntyre Signed-off-by: Linus Torvalds James Bottomley : [PATCH] fix subarch breakage in amd dual core updates The patch to arch/i386/kernel/cpu/amd.c relies on the variable cpu_core_id which is defined in i386/kernel/smpboot.c. This means it is only present if CONFIG_X86_SMP is defined, not CONFIG_SMP (alternative SMP harnesses won't have it, which is why it breaks voyager).

Miller Michael Chan : [TG3]: Split tg3_phy_probe into 2 functions Split the 1st half of tg3_phy_probe() into tg3_get_eeprom_hw_cfg() so that the TG3_FLAG_EEPROM_WRITE_PROT can be determined before calling tg3_set_power_state() in tg3_get_invariants(). This will allow tg3_set_power_state() to drive the GPIOs correctly based on the config. information in eeprom. On the 5752, there are no pull-up resistors on the GPIO pins and it is necessary to drive the unused GPIOs as output. Signed-off-by: Michael Chan Signed-off-by: David S.

Miller Michael Chan : [TG3]: Workaround 5752 A0 chip ID The 5752 A0 chip ID is wrong in hardware. The simplest way to workaround it is to change it to the correct value in tp->pci_chip_rev_id. This way, it is easier to check for the ASIC_REV_5752 in the rest of the driver. Signed-off-by: Michael Chan Signed-off-by: David S.

Provide support for drivers/char/rtc.c ioctls in the Mostek rtc driver as well as the Sparc specific RTCGET and RTCSET. This allows userspace to be much less messy. Currently util-linux and other spots jump through hoops trying various ioctl variants until it hits the right one whatever driver actually being used supports. Eventually all of this should move over to the genrtc.c driver, but not today... While we are here, fix up the register types for sparse. Thanks to Frans Pop for helping point out this issue. Signed-off-by: David S. Miller David S. Miller : [SPARC64]: In sunsu driver, make sure to fully init chip for kbd/ms We were forgetting to call sunsu_change_speed(). The reason that replugging in the mouse cable "fixes things" is that causes a BREAK interrupt which in turn caused a call to sunsu_change_speed() which would get the chip setup properly.

Noted by Brian Gerst Arun Sharma : [IA64] ia32_signal.c: erroneous use of memset/memcpy Found by Alexander Nyberg, improved by Bjorn Helgaas. - Fix the incorrect argument to sizeof() - looks like memcpy() code pass was dervived from code that used copy_from_user(). But in this case we are doing to kernel space to kernel space copy, so memcpy is the right routine, but it doesn't return an error code. Signed-off-by: Arun Sharma Signed-off-by: Tony Luck Ashok Raj : [IA64] cpu hotplug: return offlined cpus to SAL This patch is required to support cpu removal for IPF systems. Existing code just fakes the real offline by keeping it run the idle thread, and polling for the bit to re-appear in the cpu_state to get out of the idle loop. For the cpu-offline to work correctly, we need to pass control of this CPU back to SAL so it can continue in the boot-rendez mode. This gives the SAL control to not pick this cpu as the monarch processor for global MCA events, and addition does not wait for this cpu to checkin with SAL for global MCA events as well. The handoff is implemented as documented in SAL specification section 3.2.5.1 "OS_BOOT_RENDEZ to SAL return State" Ashok Raj : [IA64] Fix build errors for !HOTPLUG case.

I was not removing 1203, it's just the extension of the bcd range. You are right about 1205, as I wrote, it was a patch against 2.6.11.7. Attached is a patch against 2.6.12-rc2. > 2.

The attached patch fixes the longstanding problem with USB bcdDevice numeric ranges incorrectly converted into patterns for MODULE_ALIAS generation. Previously it put both the lower and the upper limits into the pattern, dlXdhY, making it impossible to fnmatch against except for a few special cases, like dl*dh* or dlXdhX. The patch makes it generate multiple MODULE_ALIAS lines covering the whole range with fnmatch-able patterns. E.g. for a range between 0x0001 and 0x8345 it gives the following patterns: 000[1-9] 00[1-9]* 0[1-9]* [1-7]* 8[0-2]* 83[0-3]* 834[0-5] Roman Kagan : [PATCH] USB: MODALIAS change for bcdDevice The patch below adjusts the MODALIAS generated by the usb hotplug function to match the proposed change to scripts/mod/file2alias.c.

Signed-off-by: David Hollis Acked-by: David Brownell Signed-off-by: Greg Kroah-Hartman David Brownell : [PATCH] USB: better usbnet zaurus/mdlm/... fix This is a somewhat more comprehensive fix for the problem of devices like the newer Zaurii ... or in this case some Motorola cell phones. To recap, the problem's root cause is that these devices aren't using standard USB class specifications for their network links, and so far we've had to add lots of device-specific driver entries. The vendor fix abuses the CDC MDLM descriptors (they _could_ have conformed to the spec, but didn't) and defines a "Belcarra firmware" pseudo-class. This patch recognizes that pseudo-class by the GUIDs in those descriptors, and handles the devices that just use the Zaurus framing. Signed-off-by: David Brownell Patrick Boettcher : [PATCH] USB: Fix for ati_remote when stealing code from ati_remote for a GPL-driver of my usbradio (because of its neat usb int transfers) I found out, that the inbuf is freed twice. I don't have the ati-remote, so I don't know it is a problem at all, but it looks strange to me anyway. Also I don't know if it has been fixed already in newer kernel versions.

Before 2.6.11, a NAT helper was called before the packet was NATed and had its sequence number adjusted. Since 2.6.11, the helpers get packets with already adjusted sequence numbers. This breaks sequence number adjustment, adjust_tcp_sequence() needs the original sequence number to determine whether a packet was a retransmission and to store it for further corrections.

The SELinux hooks invoke ipv6_skip_exthdr() with an incorrect length final argument. However, the length argument turns out to be superfluous. I was just reading ipv6_skip_exthdr and it occured to me that we can get rid of len altogether. The only place where len is used is to check whether the skb has two bytes for ipv6_opt_hdr. This check is done by skb_header_pointer/skb_copy_bits anyway. Now it might appear that we've made the code slower by deferring the check to skb_copy_bits. However, this check should not trigger in the common case so this is OK.

This patch introduces using the quicklists for pgd, pmd, and pte levels by combining the alloc and free functions into a common set of routines. This greatly simplifies the reading of this header file. This patch is simple but necessary for large numa configurations. It simply ensures that only pages from the local node are added to a cpus quicklist. This prevents the trapping of pages on a remote nodes quicklist by starting a process, touching a large number of pages to fill pmd and pte entries, migrating to another node, and then unmapping or exiting. With those conditions, the pages get trapped and if the machine has more than 100 nodes of the same size, the calculation of Alex Williamson : [IA64] sba_iommu bug fixes This fixes a couple of bugs in the zx1/sx1000 sba_iommu.

Surrounding that was a lock ordering problem that could have potentially deadlocked with the order the locks are grabbed in sba_unmap_single(). I moved the resource locking into sba_search_bitmap() to prevent this. Finally, there's a potential race between unmapping pdir entries and marking incoming DMA pages clean.

Optimize ia64_leave_syscall() a bit better for McKinley-type cores. The patch looks big, but that's mostly due to renaming r16/r17 to r2/r3. Good for a 13 cycle improvement. The problem is that the size of the physical stacked registers was loaded into the wrong register (r3 instead of r17). Since r17 by coincidence always had the value 1, this had the effect of turning rse_clear_invalid into a no-op. That poses the risk of leaking kernel state back to user-land and is hence not acceptable.

Miller Michael Chan : [TG3]: Fix tg3_restart_ints() tg3_restart_ints() is called to re-enable interrupts after tg3_poll() has finished all the work. It calls tg3_cond_int() to force an interrupt if the status block updated bit is set. The updated bit will be set if there is a new status block update sometime during tg3_poll() and it can be very often. The worst part is that even if all the work has been processed, the updated bit remains set and an interrupt will be forced unnecessarily. The fix is to call tg3_has_work() instead to determine if new work is posted before forcing an interrupt. The way to force an interrupt is also changed to use "coalesce_now" instead of "SETINT". The former is generally a safer way to force the interrupt.

Having a 1:1 pci:phys address mapping generally simplifies everything, so try to allocate PCI addresses from the [e0000000..ffffffff] range, which is the physical address range of the outbound PCI window on the IXP2000.

Work around this by assigning I/O addresses starting from 00010000.

In particular this provides an efficient way to retrieve the TLS value and perform atomic operations without any instruction emulation nor special system call. This even allows for pre ARMv6 binaries to be forward compatible with SMP systems without any penalty. The problematic and performance critical operations are performed through segment of kernel provided user code reachable from user space at a fixed address in kernel memory. Those fixed entry points are within the vector page so we basically get it for free as no extra memory page is required and nothing else may be mapped at that George G. Davis : [PATCH] ARM: 2655/1: ARM1136 SWP instruction abort handler fix Patch from George G.

So the v6_early_abort handler does not report the correct rd/wr direction for the SWP instruction which may result in SEGVS or hangs.

This is problematic as both CPUs will try to configure the PCI bus as they boot linux. Contrary to on the other IXP2000 platforms, the boot loader on the IXDP2800 doesn't configure the PCI bus properly, so we do want the linux instance on one of the CPUs to do that. Making one of the CPUs ignore the PCI bus (and thus act like a pure PCI slave device) is not an option because there is a 82559 NIC on the PCI bus for each of the CPUs. The chosen solution is to have the master CPU configure the PCI bus Sascha Hauer : [PATCH] ARM: 2654/1: i.MX UART initialization sets and honors UFCR value Patch from Sascha Hauer This patch adds UCFR_RFDIV setting into i.MX serial driver.

Unfortunately, for 32-bit processes we are writing the old stack pointer as a 64-bit value rather than a 32-bit value, and the process sees that as a null pointer, since it only looks at the first 32 bits, which are zero since ppc is bigendian and the stack pointer is below 4GB. This bug is in SLES9 and RHEL4 too, hence the ccs. This patch fixes the bug by making the signal code write the old stack pointer as a u32 instead of an unsigned long.

The only difference is that install has a dependency on vmlinux, kernel_install does not.

We need a way to differentiate between privileged and unprivileged reads of kernel data maintained by the audit subsystem. The AUDIT_GET operation is unprivileged: it returns the current status of the audit subsystem (e.g. whether it's enabled etc.). The AUDIT_LIST operation however returns a list of the current audit ruleset, which is considered privileged by the audit folk. To deal with this, a new SELinux permission has been implemented and applied to the operation: nlmsg_readpriv, which can be allocated to appropriately privileged Benjamin Herrenschmidt : [PATCH] ppc32: Fix errata for some G3 CPUs Some G3 CPUs can crash in funny way if a store from an FPU register instruction is executed on a register that has never been initialized since power on. This patch fixes it by making sure all FP registers have been properly initialized at kernel boot and when waking from sleep. It also makes the code that decides wether HID0_BTIC and HID0_DPM are allowed on a given CPU smarter (it can actually _clear_ them now if they are not allowed instead of just setting them when they are allowed in case the firmware got them wrong) Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds Andreas Jaggi : [PATCH] macintosh/adbhid.c: adb buttons support for aluminium PowerBook G4 This patch adds support for the special adb buttons of the aluminium PowerBook G4.

This is equivalent to the patches Roland posted already for x86 and x86-64. Note: the 64 bits .note is actually using the 32 bits format. This is normal. The ELF spec specifies a different format for 64 bits .note, but for some reason, this was never properly implemented, the core dumps for example are all using 32 bits format .note, and binutils cannot even read a 64 bits format .note. Talking to our toolchain folks, they think we'd rather stick to 32 bits format .note everywhere and get the spec fixed some day ...

This turned out to be because it was incorrectly configured as level-sensitive instead of edge-sensitive, which in turn was because the code that parses the interrupt tree that Open Firmware gives us was incorrectly assigning another device the same irq number as the sound DMA transmit interrupt (i.e. 1). This patch fixes the problem, in a somewhat quick and dirty way for now, but one which will work for all the machines we currently run on. Ultimately Ben and I want to do something more general and robust, but this should go in for 2.6.12. Paul Mackerras : [PATCH] ppc64: tell firmware about kernel capabilities On pSeries systems, according to the platform architecture specs, we are supposed to be supplying a structure to firmware that tells firmware about our capabilities, such as which version of the data structures that describe available memory we are expecting to see.

The 64bit toolchain has never had problems with incorrect mmap permissions (the 32bit has, thats why we need to retain the workaround). With these fixes as well as a gcc fix from Alan Modra (that was recently committed) 64bit apps work as expected.

It even does ldarx/stdcx in the loop, which will bounce reservations around like crazy if there's more than one CPU spinning on the same PTE (or even another PTE in the same reservation granule). The end result is that each fault takes longer when there's contention, which in turn increases the chance of another thread hitting the same fault and also piling up. Not pretty. There's two options here: 1. Do an out-of-line busy loop a'la spinlocks with just loads (no reserves) 2. Just bail and refault if needed.
