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"

* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
  ARM: 8475/1: SWP emulation: Restore original *data when failed
  ARM: 8471/1: need to save/restore arm register(r11) when it is corrupted
  ARM: fix uaccess_with_memcpy() with SW_DOMAIN_PAN
  ARM: report proper DACR value in oops dumps
  ARM: 8464/1: Update all mm structures with section adjustments
  ARM: 8465/1: mm: keep reserved ASIDs in sync with mm after multiple rollovers
