      pm2301_charger: Remove __dev* annotations · 92413a9b
      由 Lars-Peter Clausen 提交于 
      The removal of __devinit and friends seems to have overlapped with the
addition of the pm2301_charger driver. Currently the driver fails to build
with the following errors:

	drivers/power/pm2301_charger.c:843:22: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'pm2xxx_wall_charger_probe'
	drivers/power/pm2301_charger.c:1013:22: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'pm2xxx_wall_charger_remove'
	drivers/power/pm2301_charger.c:1049:11: error: 'pm2xxx_wall_charger_probe' undeclared here (not in a function)
	drivers/power/pm2301_charger.c:1050:2: error: implicit declaration of function '__devexit_p'
	drivers/power/pm2301_charger.c:1050:24: error: 'pm2xxx_wall_charger_remove' undeclared here (not in a function)

This patch removes the __dev* annotations, which fixes the build errors.

      mqueue: sys_mq_open: do not call mnt_drop_write() if read-only · 38d78e58
      由 Vladimir Davydov 提交于 
      mnt_drop_write() must be called only if mnt_want_write() succeeded,
otherwise the mnt_writers counter will diverge.

mnt_writers counters are used to check if remounting FS as read-only is
OK, so after an extra mnt_drop_write() call, it would be impossible to
remount mqueue FS as read-only.  Besides, on umount a warning would be
printed like this one:

      dma-debug: update DMA debug API to better handle multiple mappings of a buffer · 96e7d7a1
      由 Alexander Duyck 提交于 
      There were reports of the igb driver unmapping buffers without calling
dma_mapping_error.  On closer inspection issues were found in the DMA
debug API and how it handled multiple mappings of the same buffer.

The issue I found is the fact that the debug_dma_mapping_error would
only set the map_err_type to MAP_ERR_CHECKED in the case that the was
only one match for device and device address.  However in the case of
non-IOMMU, multiple addresses existed and as a result it was not setting
this field once a second mapping was instantiated.  I have resolved this
by changing the search so that it instead will now set MAP_ERR_CHECKED
on the first buffer that matches the device and DMA address that is
currently in the state MAP_ERR_NOT_CHECKED.

A secondary side effect of this patch is that in the case of multiple
buffers using the same address only the last mapping will have a valid
map_err_type.  The previous mappings will all end up with map_err_type
set to MAP_ERR_CHECKED because of the dma_mapping_error call in
debug_dma_map_page.  However this behavior may be preferable as it means
you will likely only see one real error per multi-mapped buffer, versus
the current behavior of multiple false errors mer multi-mapped buffer.

      dma-debug: fix locking bug in check_unmap() · 8d640a51
      由 Alexander Duyck 提交于 
      In check_unmap() it is possible to get into a dead-locked state if
dma_mapping_error is called.  The problem is that the bucket is locked in
check_unmap, and locked again by debug_dma_mapping_error which is called
by dma_mapping_error.  To resolve that we must release the lock on the
bucket before making the call to dma_mapping_error.
