[PATCH v7 0/4] Properly align all PT_LOAD segments with tests

[H.J. Lu]

Changes from v6:

1. Rebase.
2. Add tests for other p_align cases.

Linker may set p_align of a PT_LOAD segment larger than p_align of the
first PT_LOAD segment to satisfy a section alignment.  We should align
the first PT_LOAD segment to the maximum p_align of all PT_LOAD segments.

H.J. Lu (4):
  elf: Properly align all PT_LOAD segments [BZ #28676]
  elf: Add a test for PT_LOAD segments with mixed p_align [BZ #28676]
  elf: Add a test for PT_LOAD segments with p_align == 1 [BZ #28688]
  elf: Add a test for PT_LOAD segments with invalid p_align [BZ #28688]
