2008-03-07gigaset: fix Oops on module unload regressionTilman Schmidt
The card state mutex was only initialized when a device was connected, but used during unload unconditionally, leading to an Oops if a driver was loaded and unloaded again without ever connecting a device. Fix this by initializing the mutex as soon as the structure is allocated. Also add a missing mutex unlock revealed in the same execution path. This fixes a possible Oops in 2.6.25-rc that was introduced by commit e468c04894f36045cf93d1384183a461014b6840 ("Gigaset: permit module unload"). Thanks to Roland Kletzing for reporting this problem.

randconfig testing found a bootup lockup in drivers/char/esp.c because of a spinlock that wasn't correctly initialized.

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.

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 ... ...

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.

2008-03-06[XFS] fix inode leak in xfs_iget_core()David Chinner
If the radix_tree_preload() fails, we need to destroy the inode we just read in before trying again. This could leak xfs_vnode structures when there is memory pressure. Noticed by Christoph Hellwig.

wakeups Idle state is not being detected properly by the xfsaild push code. The current idle state is detected by an empty list which may never happen with mostly idle filesystem or one using lazy superblock counters. A single dirty item in the list that exists beyond the push target can result repeated looping attempting to push up to the target because it fails to check if the push target has been acheived or not. Fix by considering a dirty list with everything past the target as an idle state and set the timeout appropriately.

2008-03-06fb: pvr2fb: Fix up remaining section mismatch.Paul Mundt
Building with CONFIG_DEBUG_SECTION_MISMATCH=y reports: CC drivers/video/pvr2fb.o LD drivers/video/built-in.o WARNING: drivers/video/built-in.o(.text+0xb9b0): Section mismatch in reference from the function pvr2fb_check_var() to the variable .devinit.data:pvr2_fix The function pvr2fb_check_var() references the variable __devinitdata pvr2_fix. This is often because pvr2fb_check_var lacks a __devinitdata annotation or the annotation of pvr2_fix is wrong. This is obviously crap as no such reference exists, but it's a bit closer to reality from older versions which blamed the PCI table. The real problem was a reference to pvr2_var.vmode from pvr2fb_check_var(), as pvr2_var is flagged as __devinitdata (pvr2_fix is also, so at least that part is right). pvr2_var.vmode is just a fancy way of saying FB_VMODE_NONINTERLACED, so we just reference that explicitly instead.
