2011-01-07fs: d_validate fixesNick Piggin
d_validate has been broken for a long time. kmem_ptr_validate does not guarantee that a pointer can be dereferenced if it can go away at any time. Even rcu_read_lock doesn't help, because the pointer might be queued in RCU callbacks but not executed yet. So the parent cannot be checked, nor the name hashed. The dentry pointer can not be touched until it can be verified under lock. Hashing simply cannot be used. Instead, verify the parent/child relationship by traversing parent's d_child list. It's slow, but only ncpfs and the destaged smbfs care about it, at this point. Signed-off-by: Nick Piggin <npiggin@kernel.dk>

2011-01-07drm/radeon/kms/ni: load default sclk/mclk/vddc at pm initAlex Deucher
The vbios only partially initializes the memory controller on NI, so now we need to load the MC ucode in the driver and set the default clocks once the ucode is loaded. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2011-01-07drm/radeon/kms: adjust default clock/vddc tracking for pm on DCE5Alex Deucher
NI chips no longer load the MC ucode in the asic_init sequence so the asic comes up in a basic mode with low engine/memory clocks and a voltage. Once the MC ucode is loaded by the driver the card can be programmed to it's proper default clocks and voltage. As such the default clocks in the firmware info table as the post clocks, not the default running clocks. Track the default post clocks and default running clocks separately to handle this.

2011-01-07drm: Update fbdev fb_fix_screeninfoJames Simmons
If you change the color depth via fbset or some other framebuffer aware userland application struct fb_fix_screeninfo is not updated to this new information. This patch fixes this issue. Also the function is changed to just pass in struct drm_framebuffer so in the future we could use more fields.

2011-01-07dma: shdma: don't register the global die notifier multiple timesGuennadi Liakhovetski
A recent patch has added a die notifier to the shdma driver, however, it registers a static die-notifier object in the probe routine, i.e., for each device instance. This is wrong and leads to a system lockup. This patch moves the die notifier registration to module init and exit routines respectively.
