2008-03-07drivers/char/esp.c: fix bootup lockupIngo Molnar
randconfig testing found a bootup lockup in drivers/char/esp.c because of a spinlock that wasn't correctly initialized. I'm not sure why it became more prominent in 2.6.25-rc4, the bug seems rather old and i've been doing allyesconfig bootups for ages with CONFIG_ESP enabled. This fixes this bootup lockup: PM: Adding info for No Bus:ttyP63 ttyP32 at 0x0240 (irq = 0) is an ESP primary port BUG: spinlock lockup on CPU#0, swapper/1, f56dd004 Pid: 1, comm: swapper Not tainted 2.6.25-rc4-sched-devel.git-x86-latest.git #402 [<c03ac6f4>] _raw_spin_lock+0x134/0x140 [<c08649be>] _spin_lock_irqsave+0x5e/0x80 [<c0b9fbfe>] ? espserial_init+0x2be/0x6e0 [<c0b9fbfe>] espserial_init+0x2be/0x6e0 [<c0b877a3>] kernel_init+0x83/0x260 [<c0b9f940>] ? espserial_init+0x0/0x6e0 [<c010416a>] ? restore_nocheck_notrace+0x0/0xe [<c0b87720>] ? kernel_init+0x0/0x260 [<c0b87720>] ? kernel_init+0x0/0x260 [<c0104507>] kernel_thread_helper+0x7/0x10 ======================= kzalloc() is not the way to initialize spinlocks anymore.

2008-03-07sched: don't allow rt_runtime_us to be zero for groups having rt tasksDhaval Giani
This patch checks if we can set the rt_runtime_us to 0. If there is a realtime task in the group, we don't want to set the rt_runtime_us as 0 or bad things will happen.

2008-03-07sched: rt-group: fixup schedulability constraints calculationPeter Zijlstra
it was only possible to configure the rt-group scheduling parameters beyond the default value in a very small range. that's because div64_64() has a different calling convention than do_div() :/ fix a few untidies while we are here; sysctl_sched_rt_period may overflow due to that multiplication, so cast to u64 first.

2008-03-07sched: balance RT task resched only on runqueueSteven Rostedt
Sripathi Kodi reported a crash in the -rt kernel: https://bugzilla.redhat.com/show_bug.cgi?id=435674 this is due to a place that can reschedule a task without holding the tasks runqueue lock. This was caused by the RT balancing code that pulls RT tasks to the current run queue and will reschedule the current task. There's a slight chance that the pulling of the RT tasks will release the current runqueue's lock and retake it (in the double_lock_balance). During this time that the runqueue is released, the current task can migrate to another runqueue. In the prio_changed_rt code, after the pull, if the current task is of lesser priority than one of the RT tasks pulled, resched_task is called on the current task. If the current task had migrated in that small window, resched_task will be called without holding the runqueue lock for the runqueue that the task is on. This race condition also exists in the mainline kernel and this patch adds a check to make sure the task hasn't migrated before calling resched_task.

2008-03-07x86-boot: don't request VBE2 informationPeter Korsgaard
The new x86 setup code (4fd06960f120) broke booting on an old P3/500MHz with an onboard Voodoo3 of mine. After debugging it, it turned out to be caused by the fact that the vesa probing now asks for VBE2 data. Disassembing the video BIOS shows that it overflows the vesa_general_info structure when VBE2 data is requested because the source addresses for the information strings which get strcpy'ed to the buffer lie outside the 32K BIOS code (and hence contain long sequences of 0xff's).

convert_fxsr_to_user() in 2.6.24's i387_32.c did this, and convert_to_fxsr() also does the inverse, so I assume it's an oversight that it is no longer being done. [ mingo@elte.hu: we encode it this way because there's no space for the 'FPU Last Instruction Opcode' (->fop) field in the legacy user_i387_ia32_struct that PTRACE_GETFPREGS/PTRACE_SETFPREGS uses. it's probably pure legacy - i'd be surprised if any user-space relied on the FPU Last Opcode in any way.

2008-03-07x86: clear DF before calling signal handlerAurelien Jarno
The Linux kernel currently does not clear the direction flag before calling a signal handler, whereas the x86/x86-64 ABI requires that. Linux had this behavior/bug forever, but this becomes a real problem with gcc version 4.3, which assumes that the direction flag is correctly cleared at the entry of a function. This patches changes the setup_frame() functions to clear the direction before entering the signal handler.

2008-03-06slab: NUMA slab allocator migration bugfixJoe Korty
NUMA slab allocator cpu migration bugfix The NUMA slab allocator (specifically, cache_alloc_refill) is not refreshing its local copies of what cpu and what numa node it is on, when it drops and reacquires the irq block that it inherited from its caller. As a result those values become invalid if an attempt to migrate the process to another numa node occured while the irq block had been dropped. The solution is to make cache_alloc_refill reload these variables whenever it drops and reacquires the irq block. The error is very difficult to hit. When it does occur, one gets the following oops + stack traceback bits in check_spinlock_acquired: kernel BUG at mm/slab.c:2417 cache_alloc_refill+0xe6 kmem_cache_alloc+0xd0 ...

2008-03-06slub: Do not cross cacheline boundaries for very small objectsNick Piggin
SLUB should pack even small objects nicely into cachelines if that is what has been asked for. Use the same algorithm as SLAB for this. The effect of this patch for a system with a cacheline size of 64 bytes is that the 24 byte sized slab caches will now put exactly 2 objects into a cacheline instead of 3 with some overlap into the next cacheline. This reduces the object density in a 4k slab from 170 to 128 objects (same as SLAB). Signed-off-by: Nick Piggin <npiggin@suse.de> Signed-off-by: Christoph Lameter <clameter@sgi.com>

2008-03-06[IA64] update efi region debugging to use MB, GB and TB as well as KBSimon Horman
When EFI_DEBUG is defined to a non-zero value in arch/ia64/kernel/efi.c, the efi memory regions are displayed. This patch enhances the display code in a few ways: 1. Use TB, GB and MB as well as KB as units. Although this introduces rounding errors (KB doesn't as size is always a multiple of 4Kb), it does make things a lot more readable. Also as the range is also shown, it is possible to note the exact size if it is important. In my experience, the size field is mostly useful for getting a general idea of the size of a region. On the rx2620 that I use, there actually is an 8TB region (though not backed by physical memory, and 8TB really is a lot more readable than 8589934592KB. 2. pad the size field with leading spaces to further improve readability ... ...

2008-03-06Really unexport asm/page.hDavid Woodhouse
Commit ed7b1889da256977574663689b598d88950bbd23 removed page.h from include/asm-generic/Kbuild so that it shouldn't get exported. However, it was redundantly listed in asm-mn10300/Kbuild and asm-x86/Kbuild too. Remove those as well, so it really stops being exported on those architectures. Also remove the redundant listing of ptrace.h and termios.h from mn10300.

2008-03-06[ARM] 4850/1: include generic pgtable.h for !CONFIG_MMU caseGreg Ungerer
The nonmmu version of pgtable.h needs to include asm-generic/pgtable.h as well. It needs to pick up empty definitions of things like arch_enter_lazy_cpu_mode() to compile cleanly. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-03-06[ARM] 4849/1: move ATAGS asm definitionsGreg Ungerer
Move the definitions of ATAG_CORE and ATAG_CORE_SIZE in head.S to head-common.S. There is no use of these in head.S itself, but they are used in head-common.S. When building for the !CONFIG_MMU case these were not defined when compiling head-nommu.S (which includes head-common.S).

2008-03-06[ARM] 4848/1: at91: remove false lockdep warningsDavid Brownell
Remove false lockdep warnings about lock recursion when declaring IRQs as being wake-capable, by marking putting GPIO irq_desc locks into their own class.

The DNS-323, Kurobox-Pro / Linkstation-Pro, QNAP TS-109/TS-209 and some other orion-based systems have several bogus memory entries in the tag table, which causes the system to crash at startup.

2008-03-06[CRYPTO] xcbc: Fix crash with IPsecJoy Latten
When using aes-xcbc-mac for authentication in IPsec, the kernel crashes. It seems this algorithm doesn't account for the space IPsec may make in scatterlist for authtag. Thus when crypto_xcbc_digest_update2() gets called, nbytes may be less than sg[i].length. Since nbytes is an unsigned number, it wraps at the end of the loop allowing us to go back into loop and causing crash in memcpy. I used update function in digest.c to model this fix. Please let me know if it looks ok. Signed-off-by: Joy Latten <latten@austin.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
