2010-05-28ssb: fix NULL ptr deref when pcihost_wrapper is usedChristoph Fritz2-3/+7
Ethernet driver b44 does register ssb by it's pcihost_wrapper and doesn't set ssb_chipcommon. A check on this value introduced with commit d53cdbb94a52a920d5420ed64d986c3523a56743 and ea2db495f92ad2cf3301623e60cb95b4062bc484 triggers: BUG: unable to handle kernel NULL pointer dereference at 00000010 IP: [<c1266c36>] ssb_is_sprom_available+0x16/0x30 Signed-off-by: Christoph Fritz <[email protected]> Signed-off-by: John W.

2010-05-28drm/i915: Reject bind_to_gtt() early if object > apertureChris Wilson1-0/+8
If the object is bigger than the entire aperture, reject it early before evicting everything in a vain attempt to find space. v2: Use E2BIG as suggested by Owain G. Ainsworth. Signed-off-by: Chris Wilson <[email protected]> Cc: [email protected] Signed-off-by: Eric Anholt <[email protected]>

2010-05-28drm/i915: Remove spurious warning "Failure to install fence"Chris Wilson1-6/+11
This particular warning is harmless as we emit during the normal pinning process where the batch buffer requires more fences than is available without eviction. Only if we fail to evict enough fences does this become a problem, so include the requested number of fences in the ultimate *error* message. v2: Remember to compile test even trial patches to remove warnings.

2010-05-28drm/i915: Rebind bo if currently bound with incorrect alignment.Chris Wilson1-0/+11
Whilst pinning the buffer, check that that its current alignment matches the requested alignment. If it does not, rebind. This should clear up any final render errors whilst resuming, for reference: Bug 27070 - [i915] Page table errors with empty ringbuffer https://bugs.freedesktop.org/show_bug.cgi?id=27070 Bug 15502 - render error detected, EIR: 0x00000010 https://bugzilla.kernel.org/show_bug.cgi?id=15502 Bug 13844 - i915 error: "render error detected" https://bugzilla.kernel.org/show_bug.cgi?id=13844 Signed-off-by: Chris Wilson <[email protected]> Cc: [email protected] Signed-off-by: Eric Anholt <[email protected]>

2010-05-28drm/i915: Only print "nothing to do" debug message as required.Chris Wilson1-2/+3
If the FBC is already disabled, then we do not even attempt to disable FBC and so there is no point emitting a debug statement at that point, having already emitted one saying why we are disabling FBC. Signed-off-by: Chris Wilson <[email protected]> Signed-off-by: Eric Anholt <[email protected]>

2010-05-28ath9k: Fix bug in the way "bf_tx_aborted" of struct ath_buf is usedVasanthakumar Thiagarajan1-1/+3
This bug was introduced by the following commit Author: Vasanthakumar Thiagarajan <[email protected]> Date: Thu Apr 15 17:38:46 2010 -0400 ath9k: Remove ATH9K_TX_SW_ABORTED and introduce a bool for this purpose Wrong buffer is checked for bf_tx_aborted field in ath_tx_num_badfrms(), this may result in a rate scaling with wrong feedback (number of unacked frames in this case). It is the last one in the chain of buffers for an aggregate frame that should be checked. Also it misses the initialization of this field in the buffer, this may lead to a situation where we stop the sw retransmission of failed subframes associated to this buffer.

gets minix get_dir_page() in sync with its analogs; back in 2007 Nick has switched read_cache_page() and friends to sync behaviour (i.e. they wait for the page to get unlocked, check if it's uptodate and if it isn't return ERR_PTR(-EIO) instead) and removed the duplicate logics from the callers.

The wrong size was being calculated for vfinfo. In one case, it was over- calculating using nlmsg_total_size on attrs, in another case, it was under-calculating by assuming ifla_vf_* structs are packed together, but each struct is it's own attr w/ hdr (and padding).
