2012-07-30drivers/rtc/rtc-r9701.c: check that r9701_set_datetime() succeededAndrew Morton
When the driver detects that the clock time is invalid, it attempts to write a sane time into the hardware. We curently assume that everything is OK if those writes succeeded. But it is better to re-read the time from the hardware to ensure that the new settings got there OK.

2012-07-30drivers/rtc/rtc-r9701.c: avoid second call to rtc_valid_tm()Devendra Naga
r9701_get_datetime() calls rtc_valid_tm() and returns the value returned by rtc_valid_tm(), which can be used in the `if', so calling rtc_valid_tm() a second time is not required.

2012-07-30rtc: pl031: fix up IRQ flagsMattias Wallin
The pl031 interrupt is shared between the timer part and the clockwatch part of the same HW block on the ux500, so mark it IRQF_SHARED on this variant. This patch also adds the IRQF_NO_SUSPEND flag to the rtc irq on all variants as we don't want this pretty important IRQ to be disabled in suspend.

firmware_map_add_hotplug() There are two ways to create /sys/firmware/memmap/X sysfs: - firmware_map_add_early When the system starts, it is calledd from e820_reserve_resources() - firmware_map_add_hotplug When the memory is hot plugged, it is called from add_memory() But these functions are called without unifying value of end argument as below: - end argument of firmware_map_add_early() : start + size - 1 - end argument of firmware_map_add_hogplug() : start + size The patch unifies them to "start + size". Even if applying the patch, /sys/firmware/memmap/X/end file content does not change.

2012-07-30pcdp: use early_ioremap/early_iounmap to access pcdp tableGreg Pearson
efi_setup_pcdp_console() is called during boot to parse the HCDP/PCDP EFI system table and setup an early console for printk output. The routine uses ioremap/iounmap to setup access to the HCDP/PCDP table information. The call to ioremap is happening early in the boot process which leads to a panic on x86_64 systems: panic+0x01ca do_exit+0x043c oops_end+0x00a7 no_context+0x0119 __bad_area_nosemaphore+0x0138 bad_area_nosemaphore+0x000e do_page_fault+0x0321 page_fault+0x0020 reserve_memtype+0x02a1 __ioremap_caller+0x0123 ioremap_nocache+0x0012 efi_setup_pcdp_console+0x002b setup_arch+0x03a9 start_kernel+0x00d4 x86_64_start_reservations+0x012c x86_64_start_kernel+0x00fe This replaces the calls to ioremap/iounmap in efi_setup_pcdp_console() with calls to early_ioremap/early_iounmap which can be called during early boot. This patch was tested on an x86_64 prototype system which uses the HCDP/PCDP table for early console setup.

2012-07-30[media] Avoid sysfs oops when an rc_dev's raw device is absentDouglas Bagnall
For some reason, when the lirc daemon learns that a usb remote control has been unplugged, it wants to read the sysfs attributes of the disappearing device. This is useful for uncovering transient inconsistencies, but less so for keeping the system running when such inconsistencies exist. Under some circumstances (like every time I unplug my dvb stick from my laptop), lirc catches an rc_dev whose raw event handler has been removed (presumably by ir_raw_event_unregister), and proceeds to interrogate the raw protocols supported by the NULL pointer. This patch avoids the NULL dereference, and ignores the issue of how this state of affairs came about in the first place. Version 2 incorporates changes recommended by Mauro Carvalho Chehab (-ENODEV instead of -EINVAL, and a signed-off-by).

It is possible that video_put() releases video_device struct, provoking a panic when debug printk wants to get video_device node name. Signed-off-by: Ezequiel Garcia <elezegarcia@gmail.com> Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-07-30[media] vivi: fix a few format-related compliance issuesHans Verkuil
This patch will always set the field to INTERLACED (this fixes a bug were a driver should never return FIELD_ANY), and will default to YUYV pixelformat if an unknown pixelformat was specified. This way S/TRY_FMT will always return a valid format struct. Regards, Hans Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-07-31md/raid5: For odirect-write performance, do not set STRIPE_PREREAD_ACTIVE.majianpeng
'sync' writes set both REQ_SYNC and REQ_NOIDLE. O_DIRECT writes set REQ_SYNC but not REQ_NOIDLE. We currently assume that a REQ_SYNC request will not be followed by more requests and so set STRIPE_PREREAD_ACTIVE to expedite the request. This is appropriate for sync requests, but not for O_DIRECT requests. So make the setting of STRIPE_PREREAD_ACTIVE conditional on REQ_NOIDLE rather than REQ_SYNC. This is consistent with the documented meaning of REQ_NOIDLE: __REQ_NOIDLE, /* don't anticipate more IO after this one */ Signed-off-by: Jianpeng Ma <majianpeng@gmail.com> Signed-off-by: NeilBrown <neilb@suse.de>
2012-07-31md/raid1: don't abort a resync on the first badblock.NeilBrown
If a resync of a RAID1 array with 2 devices finds a known bad block one device it will neither read from, or write to, that device for this block offset. So there will be one read_target (The other device) and zero write targets. This condition causes md/raid1 to abort the resync assuming that it has finished - without known bad blocks this would be true. When there are no write targets because of the presence of bad blocks we should only skip over the area covered by the bad block. RAID10 already gets this right, raid1 doesn't. Or didn't. As this can cause a 'sync' to abort early and appear to have succeeded it could lead to some data corruption, so it suitable for -stable.
