Traffic (tcp) doesnot start on a vlan interface when gro is enabled. Even the tcp handshake was not taking place. This is because, the eth_type_trans call before the netif_receive_skb in napi_gro_finish() resets the skb->dev to napi->dev from the previously set vlan netdev interface. This causes the ip_route_input to drop the incoming packet considering it as a packet coming from a martian source. I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7. With this fix, the traffic starts and the test runs fine on both vlan and non-vlan interfaces. CC: Herbert Xu <herbert@gondor.apana.org.au> CC: Patrick McHardy <kaber@trash.net> Signed-off-by:

The netif_wake_queue() is called correctly (i.e. only on !txfull condition) from txdone routine. So Unconditional call to the netif_wake_queue() here is wrong. This might cause calling of start_xmit routine on txfull state and trigger BUG_ON. This bug does not happen when NAPI disabled. After txdone there must be at least one free tx slot. But with NAPI, this is not true anymore and the BUG_ON can hits on heavy load. In this driver NAPI was enabled on 2.6.33-rc1 so this is regression from 2.6.32 kernel. Reported-by:

803bf5ec ("fs/exec.c: restrict initial stack space expansion to rlimit") attempts to limit the initial stack to 20*PAGE_SIZE. Unfortunately, in attempting ensure the stack is not reduced in size, we ended up not changing the stack at all. This size reduction check is not necessary as the expand_stack call does this already. This caused a regression in UML resulting in most guest processes being killed. Signed-off-by:

This is retry of reverted 859ddf09 ("idr: fix a critical misallocation bug") which contained two bugs. * pa[idp->layers] should be cleared even if it's not used by sub_alloc() because it's used by mark idr_mark_full(). * The original condition check also assigned pa[l] to p which the new code didn't do thus leaving p pointing at the wrong layer. Both problems have been fixed and the idr code has received good amount testing using userland testing setup where simple bitmap allocator is run parallel to verify the result of idr allocation. The bug this patch fixes is caused by sub_alloc() optimization path bypassing out-of-room condition check and restarting allocation loop with starting value higher than maximum allowed value.

This commit changes nouveau to construct PTEs which look very much like the ones the binary driver creates.

ACPI deep C-state entry had a long standing bug/missing feature, wherein we were sending resched IPIs when an idle CPU is in mwait based deep C-state. Only mwait based C1 was using the write to the monitored address to wake up mwait'ing CPU. This patch changes the code to retain TS_POLLING bit if we are entering an mwait based deep C-state. The patch has been verified to reduce the number of resched IPIs in general and also improves the performance/power on workloads with low system utilization (i.e., when mwait based deep C-states are being used). Fixes "netperf ~50% regression with 2.6.33-rc1, bisect to 1b9508f6 " http://marc.info/?l=linux-kernel&m=126441481427331&w=4 Reported-by:

Commit 84b79f8d (drm/i915: Fix crash while aborting hibernation) attempted to fix a regression introduced by commit cbda12d7 (drm/i915: implement new pm ops for i915), but it went too far trying to split the freeze/suspend and resume/thaw parts of the code. As a result, it introduced another regression, which only is visible on some systems. Fix the problem by merging i915_drm_suspend() with i915_drm_freeze() and moving some code from i915_resume() into i915_drm_thaw(), so that intel_opregion_free() and intel_opregion_init() are also executed in the freeze and thaw code paths, respectively.
