sparc32 does not support fixmaps - so do not pretend so by having the fixmap.h file. Move relevant parts to vaddrs.h.

2012-07-26posix_types.h: Cleanup stale __NFDBITS and related definitionsJosh Boyer7-32/+12
Recently, glibc made a change to suppress sign-conversion warnings in FD_SET (glibc commit ceb9e56b3d1). This uncovered an issue with the kernel's definition of __NFDBITS if applications #include <linux/types.h> after including <sys/select.h>. A build failure would be seen when passing the -Werror=sign-compare and -D_FORTIFY_SOURCE=2 flags to gcc. It was suggested that the kernel should either match the glibc definition of __NFDBITS or remove that entirely. The current in-kernel uses of __NFDBITS can be replaced with BITS_PER_LONG, and there are no uses of the related __FDELT and __FDMASK defines. Given that, we'll continue the cleanup that was started with commit 8b3d1cda4f5f ("posix_types: Remove fd_set macros") and drop the remaining unused macros. Additionally, linux/time.h has similar macros defined that expand to nothing so we'll remove those at the same time.

2012-07-26bcma: fix invalid PMU chip control masksHauke Mehrtens1-4/+4
Commit b9562545ef0b ("bcma: complete workaround for BCMA43224 and BCM4313") introduced the wrong masks for setting the chip control registers - the "mask" parameter is inverse. It should be the mask of bits *not* changed, which is admittedly a bit non-intuitive. The incorrect mask not only causes the driver to not work correctly on the chips affected (eg the BCM43224 on the Macbook Air 4,2) but the state persists over a soft reset, causing the next boot to not necessarily see the device correctly.

2012-07-26nouveau: Fix alignment requirements on src and dst addressesMaarten Lankhorst3-10/+175
Linear copy works by adding the offset to the buffer address, which may end up not being 16-byte aligned.

Commit efc73f4b "net: Fix memory leak - vlan_info struct" adds deletion of VLAN 0 for devices with feature NETIF_F_HW_VLAN_FILTER. For driver qeth these are the layer 3 devices.
