2011-03-29x86, mtrr, pat: Fix one cpu getting out of sync during resumeSuresh Siddha
On laptops with core i5/i7, there were reports that after resume graphics workloads were performing poorly on a specific AP, while the other cpu's were ok. This was observed on a 32bit kernel specifically. Debug showed that the PAT init was not happening on that AP during resume and hence it contributing to the poor workload performance on that cpu. On this system, resume flow looked like this: 1. BP starts the resume sequence and we reinit BP's MTRR's/PAT early on using mtrr_bp_restore() 2. Resume sequence brings all AP's online 3. Resume sequence now kicks off the MTRR reinit on all the AP's. 4. For some reason, between point 2 and 3, we moved from BP to one of the AP's. My guess is that printk() during resume sequence is contributing to this. We don't see similar behavior with the 64bit kernel but there is no guarantee that at this point the remaining resume sequence (after AP's bringup) has to happen on BP. 5. set_mtrr() was assuming that we are still on BP and skipped the MTRR/PAT init on that cpu (because of 1 above) 6. But we were on an AP and this led to not reprogramming PAT on this cpu leading to bad performance. Fix this by doing unconditional mtrr_if->set_all() in set_mtrr() during MTRR/PAT init. This might be unnecessary if we are still running on BP. But it is of no harm and will guarantee that after resume, all the cpu's will be in sync with respect to the MTRR/PAT registers.

2011-03-29x86, microcode: Unregister syscore_ops after microcode unloadedXiaotian Feng
Currently, microcode doesn't unregister syscore_ops after it's unloaded. So if we modprobe then rmmod microcode, the stale microcode syscore_ops info will stay on syscore_ops_list. Later when we're trying to reboot/halt/shutdown the machine, kernel will panic on syscore_shutdown(). With the patch applied, I can reboot/halt/shutdown my machine successfully.

2011-03-28Relax si_code check in rt_sigqueueinfo and rt_tgsigqueueinfoRoland Dreier
Commit da48524eb206 ("Prevent rt_sigqueueinfo and rt_tgsigqueueinfo from spoofing the signal code") made the check on si_code too strict. There are several legitimate places where glibc wants to queue a negative si_code different from SI_QUEUE: - This was first noticed with glibc's aio implementation, which wants to queue a signal with si_code SI_ASYNCIO; the current kernel causes glibc's tst-aio4 test to fail because rt_sigqueueinfo() fails with EPERM. - Further examination of the glibc source shows that getaddrinfo_a() wants to use SI_ASYNCNL (which the kernel does not even define). The timer_create() fallback code wants to queue signals with SI_TIMER. As suggested by Oleg Nesterov <oleg@redhat.com>, loosen the check to forbid only the problematic SI_TKILL case.

2011-03-28arm: Ns9xxx: Remove private irq flow handlerThomas Gleixner
handle_prio_irq is almost identical with handle_fasteoi_irq. The subtle differences are 1) The handler checks for IRQ_DISABLED after the device handler has been called. In case it's set it masks the interrupt. 2) When the handler sees IRQ_DISABLED on entry it masks the interupt in the same way as handle_fastoei_irq, but does not set the IRQ_PENDING flag. 3) Instead of gracefully handling a recursive interrupt it crashes the kernel. #1 is just relevant when a device handler calls disable_irq_nosync() and it does not matter whether we mask the interrupt right away or not. We handle lazy masking for disable_irq anyway, so there is no real reason to have this extra mask in place. #2 will prevent the resend of a pending interrupt, which can result in lost interrupts for edge type interrupts. For level type interrupts the resend is a noop in the generic code. According to the datasheet all interrupts are level type, so marking them as such will result in the exact same behaviour as the private handle_prio_irq implementation. #3 is just stupid. Crashing the kernel instead of handling a problem gracefully is just wrong. With the current semantics- all handlers run with interrupts disabled - this is even more wrong. Rename ack to eoi, remove the unused mask_ack, switch to handle_fasteoi_irq and remove the private function.

2011-03-28drbd: fix up merge errorLinus Torvalds
In commit 95a0f10cddbf ("drbd: store in-core bitmap little endian, regardless of architecture") drbd had made the sane choice to use little-endian bitmap functions everywhere. However, it used the horrible old functions names from <asm-generic/bitops/le.h>, that were never really meant to be exported. In the meantime, things got cleaned up, and in commit c4945b9ed472 ("asm-generic: rename generic little-endian bitops functions") we renamed the LE bitops to something sane, exactly so that they could be used in random code without people gouging their eyes out when seeing the crazy jumble of letters that were the old internal names. As a result the drbd thing merged cleanly (commit 8d49a77568d1: "Merge branch 'for-2.6.39/drivers' of git://git.kernel.dk/linux-2.6-block"), since there was no data conflict - but the end result obviously doesn't actually compile.

Acer WMI hotkey event's result include current device status, just need sync the status to killswitch after acer-wmi driver receive hotkey event but not always poll device status. This is good for performance. But, if use EC raw mode, Acer BIOS will not emit wmi event and leave EC to control device status. So, still startup polling job when doesn't detect WMI event GUID or user choice to use ec_raw_mode. Tested on Acer TravelMate 8572 notebook.

2011-03-28acer-wmi: does not set persistence state by rfkill_init_sw_stateLee, Chun-Yi
Acer BIOS keeps devices state when system reboot, but reset to default device states (Wlan on, Bluetooth off, wwan on) if system cold boot. That means BIOS's initial state is not always real persistence. So, removed rfkill_init_sw_state because it sets initial state to persistence then replicate to other new killswitch when rfkill-input enabled. After removed it, acer-wmi set initial soft-block state after rfkill register, and doesn't allow set_block until rfkill initial finished.

In the earlier check we assumed that "obj" could be NULL. I looked at some of the other places that call evaluate_object() and they check for NULL as well. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>

dmi_check_system() walks the table running matching functions until someone returns non zero or we hit the end. This patch makes dmi_check_cb to return 1 so dmi_check_system() return immediately when a match is found. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>

I found the commit 80183a4b "compal-laptop/fujitsu-laptop/msi-laptop: make dmi_check_cb to return 1 instead of 0" has wrong patch merge. The original patch change the return value for dmi_check_cb(): https://lkml.org/lkml/2010/7/2/88 But commit 80183a4b changed the return value for set_backlight_level.
