Subject: sh: Update the alignment when 4K stacks are used.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=bdf4fa536ba5c6eff125f18231d54e227b1f3629;p=deliverable%2Flinux.git

sh: Update the alignment when 4K stacks are used.

Use the newly added .bss.page_aligned section for aligning the stacks
rather than THREAD_SIZE.
