Pull arm64 fixes from Will Deacon:
 "I'm safely chained back up to my desk, so please pull these arm64
  fixes for -rc1 that address some issues that cropped up during the
  merge window:

   - Prevent KASLR from mapping the top page of the virtual address
     space

   - Fix device-tree probing of SDEI driver

   - Fix incorrect register offset definition in Hisilicon DDRC PMU
     driver

   - Fix compilation issue with older binutils not liking unsigned
     immediates

   - Fix uapi headers so that libc can provide its own sigcontext
     definition

   - Fix handling of private compat syscalls

   - Hook up compat io_pgetevents() syscall for 32-bit tasks

   - Cleanup to arm64 Makefile (including now to avoid silly conflicts)"
