Pull sparc fixes from David Miller:
 "Couple of small bug fixes:

   1) strlcpy in ldom_reboot() is still not quite right, use sprintf
      instead from Kees Cook.

   2) Generic hugetlb interface pte checks should use the widest return
      type, otherwise high bits can get chopped off.

   3) Fix build with PCI MSI enabled on 32-bit sparc"

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
  sparc: fix MSI build failure on Sparc32
  sparc: remove deprecated IRQF_DISABLED
  mm: Fix generic hugetlb pte check return type.
  sparc: fix ldom_reboot buffer overflow harder
