Subject: [PATCH] arm64: Fix compilation error while accessing MPIDR_HWID_BITMASK from .S files
Date:   Mon, 19 Feb 2018 12:09:54 +0530

Since commit e1a50de37860b3a93a9d643b09638db5aff47650 (arm64: cputype:
Silence Sparse warnings), compilation of arm64 architecture is broken
with the following error messages:

  AR      arch/arm64/kernel/built-in.o
  arch/arm64/kernel/head.S: Assembler messages:
  arch/arm64/kernel/head.S:677: Error: found 'L', expected: ')'
  arch/arm64/kernel/head.S:677: Error: found 'L', expected: ')'
  arch/arm64/kernel/head.S:677: Error: found 'L', expected: ')'
  arch/arm64/kernel/head.S:677: Error: junk at end of line, first
  unrecognized character is `L'
  arch/arm64/kernel/head.S:677: Error: unexpected characters following
  instruction at operand 2 -- `movz x1,:abs_g1_s:0xff00ffffffUL'
  arch/arm64/kernel/head.S:677: Error: unexpected characters following
  instruction at operand 2 -- `movk x1,:abs_g0_nc:0xff00ffffffUL'

This patch fixes the same by using the UL() macro correctly for
assigning the MPIDR_HWID_BITMASK macro value.
