2010-10-21microblaze: Report if only one timer is usedMichal Simek
Kernel needs two timers because of clocksource and clockevent. It is better to show warning message directly on early console if available. If it isn't available kernel log buffer contains it. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-10-21microblaze: Clear return value in pt_regsMichal Simek
Signal code uses r3 value which saved in restore_sigcontext to rt_sigframe but it require to be zeroed. If is not zero rt_sigframe contains wrong values. Signed-off-by: Michal Simek <monstr@monstr.eu>

2010-10-15ubd: fix incorrect sector handling during request restartTejun Heo
Commit f81f2f7c (ubd: drop unnecessary rq->sector manipulation) dropped request->sector manipulation in preparation for global request handling cleanup; unfortunately, it incorrectly assumed that the updated sector wasn't being used. ubd tries to issue as many requests as possible to io_thread. When issuing fails due to memory pressure or other reasons, the device is put on the restart list and issuing stops. On IO completion, devices on the restart list are scanned and IO issuing is restarted. ubd issues IOs sg-by-sg and issuing can be stopped in the middle of a request, so each device on the restart queue needs to remember where to restart in its current request. ubd needs to keep track of the issue position itself because, * blk_rq_pos(req) is now updated by the block layer to keep track of _completion_ position. * Multiple io_req's for the current request may be in flight, so it's difficult to tell where blk_rq_pos(req) currently is. Add ubd->rq_pos to keep track of the issue position and use it to correctly restart io_req issue.

2010-10-14Don't dump task struct in a.out core-dumpsLinus Torvalds
akiphie points out that a.out core-dumps have that odd task struct dumping that was never used and was never really a good idea (it goes back into the mists of history, probably the original core-dumping code). Just remove it. Also do the access_ok() check on dump_write(). It probably doesn't matter (since normal filesystems all seem to do it anyway), but he points out that it's normally done by the VFS layer, so ... [ I suspect that we should possibly do "vfs_write()" instead of calling ->write directly. That also does the whole fsnotify and write statistics thing, which may or may not be a good idea. ] And just to be anal, do this all for the x86-64 32-bit a.out emulation code too, even though it's not enabled (and won't currently even compile) Reported-by: akiphie <akiphie@lavabit.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2010-10-12ARM: 6440/1: ep93xx: DMA: fix channel_disableMika Westerberg
When channel_disable() is called, it disables per channel interrupts and waits until channels state becomes STATE_STALL, and then disables the channel. Now, if the DMA transfer is disabled while the channel is in STATE_NEXT we will not wait anything and disable the channel immediately. This seems to cause weird data corruption for example in audio transfers. Fix is to wait while we are in STATE_NEXT or STATE_ON and only then disable the channel.

2010-10-11x86, AMD, MCE thresholding: Fix the MCi_MISCj iteration orderBorislav Petkov
This fixes possible cases of not collecting valid error info in the MCE error thresholding groups on F10h hardware. The current code contains a subtle problem of checking only the Valid bit of MSR0000_0413 (which is MC4_MISC0 - DRAM thresholding group) in its first iteration and breaking out if the bit is cleared. But (!), this MSR contains an offset value, BlkPtr[31:24], which points to the remaining MSRs in this thresholding group which might contain valid information too. But if we bail out only after we checked the valid bit in the first MSR and not the block pointer too, we miss that other information. The thing is, MC4_MISC0[BlkPtr] is not predicated on MCi_STATUS[MiscV] or MC4_MISC0[Valid] and should be checked prior to iterating over the MCI_MISCj thresholding group, irrespective of the MC4_MISC0[Valid] setting.

HWCAP_TLS is needed if support for earlier ARMv6 is compiled into the same kernel. Without HWCAP_TLS flags the userspace won't work unless nosmp is specified: Kernel panic - not syncing: Attempted to kill init!

2010-10-08ARM: 6436/1: AT91: Fix power-saving in idle-mode on 926T processorsAnders Larsen
According to Atmel, their 926T processors (AT91 post RM9200) requires 'Wait for Interrupt' mode be entered right after disabling the processor clock in order to minimise current consumption when idle, so do both provided we're not running on a 920T (an RM9200). Furthermore, get rid of the #ifndef CONFIG_DEBUG_KERNEL, since arch_idle() can be turned off completely with the kernel parameter 'nohlt'.
