The quirks module parameter is or'ed with the built-in quirks for the

The realtime clock provided by do_gettimeofday() is affected by time
jumps caused by NTP or DST. Furthermore, preliminary investigation
showed that SMP systems the realtime clock is based on the CPU TSC,
and those could get slightly out of sync, resulting in jitter in the
timestamps depending on which processor handles the USB interrupts.
Instead of the realtime clock, use a monotonic high resolution clock to
timestamp the buffer. As this could in theory introduce a regression
with some userspace applications expecting a realtime clock timestamp,
add a module parameter to switch back to the realtime clock.
Thanks to Paulo Assis for pointing out and investigating the issue.

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.

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.

803bf5ec25 ("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.

This is retry of reverted 859ddf0974
("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. For detailed
description, please read commit message of 859ddf09.
