Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/egtvedt/linux-avr32
Pull AVR32 fixes from Hans-Christian Egtvedt. Fix build warnings and use the Kbuild infrastructure for generic headers rather than doing it by hand. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/egtvedt/linux-avr32: avr32: cast syscall_return to silence compiler warning avr32: fix clockevents kernel warning avr32: use Kbuild infrastructure to handle the asm-generic headers
