2017-10-04drm: fix typo in drm_gem_get_pages() commentJordan Crouse
I spent an embarrassingly long time looking for drm_gem_init_object() before I realized I was actually looking for drm_gem_object_init(). Fix the typo to keep other poor developers from suffering the same fate.

But, that change fixes a typo in a user visible API that was just added in this merge window, so if we fix it now, we can fix it. If we don't, the typo is in the API forever.

2017-09-27scsi: aacraid: Add a small delay after IOP resetGuilherme G. Piccoli
Commit 0e9973ed3382 ("scsi: aacraid: Add periodic checks to see IOP reset status") changed the way driver checks if a reset succeeded. Now, after an IOP reset, aacraid immediately start polling a register to verify the reset is complete. This behavior cause regressions on the reset path in PowerPC (at least). Since the delay after the IOP reset was removed by the aforementioned patch, the fact driver just starts to read a register instantly after the reset was issued (by writing in another register) "corrupts" the reset procedure, which ends up failing all the time. The issue highly impacted kdump on PowerPC, since on kdump path we proactively issue a reset in adapter (through the reset_devices kernel parameter). This patch (re-)adds a delay right after IOP reset is issued. Empirically we measured that 3 seconds is enough, but for safety reasons we delay for 5s (and since it was 30s before, 5s is still a small amount). For reference, without this patch we observe the following messages on kdump kernel boot process: [ 76.294] aacraid 0003:01:00.0: IOP reset failed [ 76.294] aacraid 0003:01:00.0: ARC Reset attempt failed [ 86.524] aacraid 0003:01:00.0: adapter kernel panic'd ff.

2017-09-27ACPI / APEI: clear error status before acknowledging the errorTyler Baicar
Currently we acknowledge errors before clearing the error status. This could cause a new error to be populated by firmware in-between the error acknowledgment and the error status clearing which would cause the second error's status to be cleared without being handled. So, clear the error status before acknowledging the errors. Also, make sure to acknowledge the error if the error status read fails.
