Merge branch 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King:
"Further ARM fixes:
- Anson Huang noticed that we were corrupting a register we shouldn't
be during suspend on some CPUs.
- Shengjiu Wang spotted a bug in the 'swp' instruction emulation.
- Will Deacon fixed a bug in the ASID allocator.
- Laura Abbott fixed the kernel permission protection to apply to all
threads running in the system.
- I've fixed two bugs with the domain access control register
handling, one to do with printing an appropriate value at oops
time, and the other to further fix the uaccess_with_memcpy code"
