2012-04-12drm/i915: clear fencing tracking state when retiring requestsDaniel Vetter
This fixes a resume regression introduced in commit 7dd4906586274f3945f2aeaaa5a33b451c3b4bba Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Mar 21 10:48:18 2012 +0000 drm/i915: Mark untiled BLT commands as fenced on gen2/3 which fixed fencing tracking for untiled blt commands. A side effect of that patch was that now also untiled objects have a non-zero obj->last_fenced_seqno to track when a fence can be set up after a pipelined tiling change. Unfortunately this was only cleared by the fence setup and teardown code, resulting in tons of untiled but inactive objects with non-zero last_fenced_seqno. Now after resume we completely reset the seqno tracking, both on the driver side (by setting dev_priv->next_seqno = 1) and on the hw side (by allocating a new hws page, which contains the seqnos). Hilarity and indefinite waits ensued from the stale seqnos in obj->last_fenced_seqno from before the suspend. The fix is to properly clear the fencing tracking state like we already do for the normal gpu rendering while moving objects off the active list. Reported-and-tested-by: "Rafael J.

2012-04-12irq_domain: Move irq_virq_count into NOMAP revmapGrant Likely
This patch replaces the old global setting of irq_virq_count that is only used by the NOMAP mapping and instead uses a revmap_data property so that the maximum NOMAP allocation can be set per NOMAP irq_domain. There is exactly one user of irq_virq_count in-tree right now: PS3. Also, irq_virq_count is only useful for the NOMAP mapping. So, instead of having a single global irq_virq_count values, this change drops it entirely and added a max_irq argument to irq_domain_add_nomap(). That makes it a property of an individual nomap irq domain instead of a global system settting.

2012-04-12md/bitmap: prevent bitmap_daemon_work running while initialising bitmapNeilBrown
If a bitmap is added while the array is active, it is possible for bitmap_daemon_work to run while the bitmap is being initialised. This is particularly a problem if bitmap_daemon_work sees bitmap->filemap as non-NULL before it has been filled in properly. So hold bitmap_info.mutex while filling in ->filemap to prevent problems.

If, in drivers/input/misc/da9052_onkey.c::da9052_onkey_probe(), the call to either kzalloc() or input_allocate_device() fails then we will return -ENOMEM from the function without freeing the other allocation that may have succeeded, thus we leak either the memory allocated for 'onkey' or the memory allocated for 'input_dev' if one succeeds and the other fails. Fix that by jumping to the 'err_free_mem' label at the end of the function that properly cleans up rather than returning directly.

2012-04-11x86: merge 32/64-bit versions of 'strncpy_from_user()' and speed it upLinus Torvalds
This merges the 32- and 64-bit versions of the x86 strncpy_from_user() by just rewriting it in C rather than the ancient inline asm versions that used lodsb/stosb and had been duplicated for (trivial) differences between the 32-bit and 64-bit versions. While doing that, it also speeds them up by doing the accesses a word at a time. Finally, the new routines also properly handle the case of hitting the end of the address space, which we have never done correctly before (fs/namei.c has a hack around it for that reason). Despite all these improvements, it actually removes more lines than it adds, due to the de-duplication. Also, we no longer export (or define) the legacy __strncpy_from_user() function (that was defined to not do the user permission checks), since it's not actually used anywhere, and the user address space checks are built in to the new code. Other architecture maintainers have been notified that the old hack in fs/namei.c will be going away in the 3.5 merge window, in case they copied the x86 approach of being a bit cavalier about the end of the address space.

keyctl_session_to_parent(task) sets ->replacement_session_keyring, it should be processed and cleared by key_replace_session_keyring(). However, this task can fork before it notices TIF_NOTIFY_RESUME and the new child gets the bogus ->replacement_session_keyring copied by dup_task_struct(). This is obviously wrong and, if nothing else, this leads to put_cred(already_freed_cred). change copy_creds() to clear this member.

In commit 4bbdd45a (irq_domain/powerpc: eliminate irq_map; use irq_alloc_desc() instead) code was added that ignores error returns from irq_alloc_desc_from() by (silently) casting the return value to unsigned. The negitive value error return now suddenly looks like a valid irq number. Commits cc79ca69 (irq_domain: Move irq_domain code from powerpc to kernel/irq) and 1bc04f2c (irq_domain: Add support for base irq and hwirq in legacy mappings) move this code to its current location in irqdomain.c The result of all of this is a null pointer dereference OOPS if one of the error cases is hit.

2012-04-11powerpc: Fix typo in runlatch codeBenjamin Herrenschmidt
Commit fe1952fc0afb9a2e4c79f103c08aef5d13db1873 "powerpc: Rework runlatch code" has a nasty typo where it uses "TLF_RUNLATCH" instead of "_TLF_RUNLATCH" (bit number instead of bit mask), causing some flags to be potentially lost such as _TLF_RESTORE_SIGMASK (Brown paper bag for me ! We should be able to make that break at compile time with a bit of magic, any volunteer ?) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2012-04-10drm/i915: properly compute dp dithering for user-created modesDaniel Vetter
We've only computed whether we need to fall back to 6bpc due to dp link bandwidth constrains in mode_valid, but not mode_fixup. Under various circumstances X likes to create new modes which then lack proper 6bpc flags (if required), resulting in mode_fixup failures and ultimately black screens. Chris Wilson pointed out that we still get things wrong for bpp > 24, but that should be fixed in another patch (and it'll be easier because this patch consolidates the logic). The likely culprit for this regression is commit 3d794f87238f74d80e78a7611c7fbde8a54c85c2 Author: Keith Packard <keithp@keithp.com> Date: Wed Jan 25 08:16:25 2012 -0800 drm/i915: Force explicit bpp selection for intel_dp_link_required v2: Fix indentation and tune down the too bold claim that this should fix the world.

2012-04-10GFS2: Allow caching of rindex glockBob Peterson
This patch allows caching of the rindex glock. We were previously setting the GL_NOCACHE bit when the glock was released. That forced the rindex inode to be invalidated, which caused us to re-read rindex at the next access. However, it caused the glock to be unnecessarily bounced around the cluster. This patch allows the glock to remain cached, but it still causes the rindex to be re-read once it has been written to by gfs2_grow. Ben and I have tested single-node gfs2_grow cases and I've tested clustered gfs2_grow cases on my four-node cluster.
