This refreshes the line numbers, removes any fuzz (which would make any future forward ports easier) and standardizes the patch/file headers (which makes them easier to read). Signed-off-by: Alexey Neyman <stilor@att.net>

Subject: [PATCH] gold: Place .note.gnu.property section before other note
|
|
sections
|
|
|
|
Place the .note.gnu.property section before all other note sections to
|
|
avoid being placed between other note sections with different alignments.
|
|
|
|
PR gold/28494
|
|
* layout.cc (Layout::create_note): Set order to ORDER_PROPERTY_NOTE
|
|
for the .note.gnu.property section.
|
|
* layout.h (Output_section_order): Add ORDER_PROPERTY_NOTE.
|
|
|
|
(cherry picked from commit f85dcfc3af9cf7c2859241253f1d37b1133abea2)
