2008-08-21pkt_sched: Fix qdisc_watchdog() vs. dev_deactivate() raceJarek Poplawski
dev_deactivate() can skip rescheduling of a qdisc by qdisc_watchdog() or other timer calling netif_schedule() after dev_queue_deactivate(). We prevent this checking aliveness before scheduling the timer. Since during deactivation the root qdisc is available only as qdisc_sleeping additional accessor qdisc_root_sleeping() is created.

2008-08-20fbdefio: add set_page_dirty handler to deferred IO FBIan Campbell
Fixes kernel BUG at lib/radix-tree.c:473. Previously the handler was incidentally provided by tmpfs but this was removed with: commit 14fcc23fdc78e9d32372553ccf21758a9bd56fa1 Author: Hugh Dickins <hugh@veritas.com> Date: Mon Jul 28 15:46:19 2008 -0700 tmpfs: fix kernel BUG in shmem_delete_inode relying on this behaviour was incorrect in any case and the BUG also appeared when the device node was on an ext3 filesystem. v2: override a_ops at open() time rather than mmap() time to minimise races per AKPM's concerns.

2008-08-20mm: dirty page tracking race fixNick Piggin
There is a race with dirty page accounting where a page may not properly be accounted for. clear_page_dirty_for_io() calls page_mkclean; then TestClearPageDirty. page_mkclean walks the rmaps for that page, and for each one it cleans and write protects the pte if it was dirty. It uses page_check_address to find the pte. That function has a shortcut to avoid the ptl if the pte is not present. Unfortunately, the pte can be switched to not-present then back to present by other code while holding the page table lock -- this should not be a signal for page_mkclean to ignore that pte, because it may be dirty. For example, powerpc64's set_pte_at will clear a previously present pte before setting it to the desired value. There may also be other code in core mm or in arch which do similar things. The consequence of the bug is loss of data integrity due to msync, and loss of dirty page accounting accuracy. XIP's __xip_unmap could easily also be unreliable (depending on the exact XIP locking scheme), which can lead to data corruption. Fix this by having an option to always take ptl to check the pte in page_check_address. It's possible to retain this optimization for page_referenced and try_to_unmap.

2008-08-20fix setpriority(PRIO_PGRP) thread iterator breakageKen Chen
When user calls sys_setpriority(PRIO_PGRP ...) on a NPTL style multi-LWP process, only the task leader of the process is affected, all other sibling LWP threads didn't receive the setting. The problem was that the iterator used in sys_setpriority() only iteartes over one task for each process, ignoring all other sibling thread. Introduce a new macro do_each_pid_thread / while_each_pid_thread to walk each thread of a process. Convert 4 call sites in {set/get}priority and ioprio_{set/get}.

2008-08-20Reduce brokenness of CRIS headers_installDavid Woodhouse
I won't say 'fix', because they still look broken, although this will at least allow 'make ARCH=CRIS headers_install' to _complete_. For headers which are exported, we should probably choose between asm/arch-v10 and asm/arch-v32 by something that GCC defines -- we can't rely on a generated symlink. And we certainly can't export an arch/ directory which doesn't even exist. And the only thing that we seem to include from the arch/ directory is <asm/arch/ptrace.h> from <asm/ptrace.h> ... and that isn't exported in either arch-v10 or arch-v32 _anyway_.

2008-08-18x86, percpu: silence section mismatch warnings related to EARLY_PER_CPU ↵Marcin Slusarz
variables Quoting Mike Travis in "x86: cleanup early per cpu variables/accesses v4" (23ca4bba3e20c6c3cb11c1bb0ab4770b724d39ac): The DEFINE macro defines the per_cpu variable as well as the early map and pointer. It also initializes the per_cpu variable and map elements to "_initvalue". The early_* macros provide access to the initial map (usually setup during system init) and the early pointer. This pointer is initialized to point to the early map but is then NULL'ed when the actual per_cpu areas are setup. After that the per_cpu variable is the correct access to the variable. As these variables are NULL'ed before __init sections are dropped (in setup_per_cpu_maps), they can be safely annotated as __ref. This change silences following section mismatch warnings: WARNING: vmlinux.o(.data+0x46c0): Section mismatch in reference from the variable x86_cpu_to_apicid_early_ptr to the variable .init.data:x86_cpu_to_apicid_early_map The variable x86_cpu_to_apicid_early_ptr references the variable __initdata x86_cpu_to_apicid_early_map If the reference is valid then annotate the variable with __init* (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, WARNING: vmlinux.o(.data+0x46c8): Section mismatch in reference from the variable x86_bios_cpu_apicid_early_ptr to the variable .init.data:x86_bios_cpu_apicid_early_map The variable x86_bios_cpu_apicid_early_ptr references the variable __initdata x86_bios_cpu_apicid_early_map If the reference is valid then annotate the variable with __init* (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, WARNING: vmlinux.o(.data+0x46d0): Section mismatch in reference from the variable x86_cpu_to_node_map_early_ptr to the variable .init.data:x86_cpu_to_node_map_early_map The variable x86_cpu_to_node_map_early_ptr references the variable __initdata x86_cpu_to_node_map_early_map If the reference is valid then annotate the variable with __init* (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Cc: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-08-18x86: correct register constraints for 64-bit atomic operationsMathieu Desnoyers
x86_64 add/sub atomic ops does not seems to accept integer values bigger than 32 bits as immediates. Intel's add/sub documentation specifies they have to be passed as registers. The only operations in the x86-64 architecture which accept arbitrary 64-bit immediates is "movq" to any register; similarly, the only operation which accept arbitrary 64-bit displacement is "movabs" to or from al/ax/eax/rax. http://gcc.gnu.org/onlinedocs/gcc-4.3.0/gcc/Machine-Constraints.html states : e 32-bit signed integer constant, or a symbolic reference known to fit that range (for immediate operands in sign-extending x86-64 instructions). Z 32-bit unsigned integer constant, or a symbolic reference known to fit that range (for immediate operands in zero-extending x86-64 instructions). Since add/sub does sign extension, using the "e" constraint seems appropriate. It applies to 2.6.27-rc, 2.6.26, 2.6.25...

This new state lets dev_deactivate() mark a qdisc as having been deactivated. dev_queue_xmit() and ing_filter() check for this bit and do not try to process the qdisc if the bit is set. dev_deactivate() polls the qdisc after setting the bit, waiting for both __QDISC_STATE_RUNNING and __QDISC_STATE_SCHED to clear. This isn't perfect yet, but subsequent changesets will make it so. This part is just one piece of the puzzle. Signed-off-by: David S. Miller <davem@davemloft.net>

The exported copy of videodev2.h contains this line: #define #include <sys/time.h> This is because for some reason it defines __user for itself -- despite the fact that we remove all instances of __user when exporting headers. _All_ pointers in userspace are user pointers. Fix it by removing the unnecessary '#define __user' from the file. The new headers ivtv.h and ivtvfb.h would have the same problem... if whoever put them there had actually remembered to add them to the Kbuild file while he was at it. Fix those too, and export them as was presumably intended. Note that includes of <linux/compiler.h> are also stripped by the header export process, so those don't need to be conditional.

2008-08-15x86: add MAP_STACK mmap flagIngo Molnar
as per this discussion: http://lkml.org/lkml/2008/8/12/423 Pardo reported that 64-bit threaded apps, if their stacks exceed the combined size of ~4GB, slow down drastically in pthread_create() - because glibc uses MAP_32BIT to allocate the stacks. The use of MAP_32BIT is a legacy hack - to speed up context switching on certain early model 64-bit P4 CPUs. So introduce a new flag to be used by glibc instead, to not constrain 64-bit apps like this. glibc can switch to this new flag straight away - it will be ignored by the kernel. If those old CPUs ever matter to anyone, support for it can be implemented.

This moves it to being a tty operation. That removes special cases and now also means that resize can be picked up by um and other non vt consoles which may have a resize operation. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

WARNING: vmlinux.o(.text+0xe684): Section mismatch in reference from the function register_nosave_region() to the function .init.text:__register_nosave_region() The function register_nosave_region() references the function __init __register_nosave_region(). This is often because register_nosave_region lacks a __init annotation or the annotation of __register_nosave_region is wrong. register_nosave_region calls __init function and is called only from __init functions Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Acked-by: Rafael J.
