Bug Description

Some builds don't honour the ALIGNED(SIZE) hint on stress_icache_func which means the mprotect on the page fail because the address of the function is not page aligned. We need to round down to the start of the page so that mprotects do not fail.

  * Actually include the patches for the following fixes (previous upload didn't
    have them).
  - stress-opcode: unmap the shared region to avoid clobbering it (LP: #1632989)
  - stress-icache: ensure we mprotect on page aligned boundary (LP: #1632991)
