2012-04-02tile: fix multiple build failures from system.h dismantlePaul Gortmaker
Commit bd119c69239322caafdb64517a806037d0d0c70a "Disintegrate asm/system.h for Tile" created the asm/switch_to.h file, but did not add an include of it to all its users. Also, commit b4816afa3986704d1404fc48e931da5135820472 "Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h" introduced the concept of asm/cmpxchg.h but the tile arch never got one. Fork the cmpxchg content out of the asm/atomic.h file to create one.

2012-04-02irq_work: fix compile failure on MIPS from system.h splitPaul Gortmaker
Builds of the MIPS platform ip32_defconfig fails as of commit 0195c00244dc ("Merge tag 'split-asm_system_h ...") because MIPS xchg() macro uses BUILD_BUG_ON and it was moved in commit b81947c646bf ("Disintegrate asm/system.h for MIPS"). The root cause is that the system.h split wasn't tested on a baseline with commit 6c03438edeb5 ("kernel.h: doesn't explicitly use bug.h, so don't include it.") Since this file uses BUG code in several other places besides the xchg call, simply make the inclusion explicit.

2012-04-02nouveau/bios: Fix tracking of BIOS image dataBenjamin Herrenschmidt
The code tries various methods for retreiving the BIOS data. However it doesn't clear the bios->data pointer between the iterations. In some cases, the shadow() method will fail and not update bios->data at all, which will cause us to "score" the old data and incorrectly attribute that score to the new method. This can cause double frees later when disposing of the unused data. Additionally, we were not freeing the data for methods that fail the score test (we only freed when a "best" is superseeded, not when the new method has a lower score than the exising "best"). Fix that as well. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2012-04-01ipv6: Fix RTM_GETROUTE's interpretation of RTA_IIF to be consistent with ipv4Shmulik Ladkani
In IPv4, if an RTA_IIF attribute is specified within an RTM_GETROUTE message, then a route is searched as if a packet was received on the specified 'iif' interface. However in IPv6, RTA_IIF is not interpreted in the same way: 'inet6_rtm_getroute()' always calls 'ip6_route_output()', regardless the RTA_IIF attribute. As a result, in IPv6 there's no way to use RTM_GETROUTE in order to look for a route as if a packet was received on a specific interface. Fix 'inet6_rtm_getroute()' so that RTA_IIF is interpreted as "lookup a route as if a packet was received on the specified interface", similar to IPv4's 'inet_rtm_getroute()' interpretation.
