2011-12-20drm/radeon: Add radeon_test_syncing function v2Christian König
Tests syncing between all rings by using semaphores and fences. v2: use radeon_testing as a bit flag rather than on/off switch this allow to test for one thing at a time (bo_move or semaphore test). It kind of break the usage if user wheren't using 1 for bo move test but as it's a test feature i believe it's ok.

2011-12-20sctp: Do not account for sizeof(struct sk_buff) in estimated rwndThomas Graf
When checking whether a DATA chunk fits into the estimated rwnd a full sizeof(struct sk_buff) is added to the needed chunk size. This quickly exhausts the available rwnd space and leads to packets being sent which are much below the PMTU limit. This can lead to much worse performance. The reason for this behaviour was to avoid putting too much memory pressure on the receiver. The concept is not completely irational because a Linux receiver does in fact clone an skb for each DATA chunk delivered. However, Linux also reserves half the available socket buffer space for data structures therefore usage of it is already accounted for. When proposing to change this the last time it was noted that this behaviour was introduced to solve a performance issue caused by rwnd overusage in combination with small DATA chunks. Trying to reproduce this I found that with the sk_buff overhead removed, the performance would improve significantly unless socket buffer limits are increased. The following numbers have been gathered using a patched iperf supporting SCTP over a live 1 Gbit ethernet network. The -l option was used to limit DATA chunk sizes. The numbers listed are based on the average of 3 test runs each. Default values have been used for sk_(r|w)mem.

2011-12-20mlx4_en: FIX: Setting default_qpn before using itYevgeny Petrilin
When UDP RSS is enabled, we use same QPN for TCP and UDP ranges The bug is that the default_qpn was used base UDP qpn before it was set.

2011-12-20binary_sysctl(): fix memory leakMichel Lespinasse
binary_sysctl() calls sysctl_getname() which allocates from names_cache slab usin __getname() The matching function to free the name is __putname(), and not putname() which should be used only to match getname() allocations. This is because when auditing is enabled, putname() calls audit_putname *instead* (not in addition) to __putname(). Then, if a syscall is in progress, audit_putname does not release the name - instead, it expects the name to get released when the syscall completes, but that will happen only if audit_getname() was called previously, i.e. if the name was allocated with getname() rather than the naked __getname(). So, __getname() followed by putname() ends up leaking memory.
