Subject: linux: Add MMAP_ABOVE4G from Linux 6.6 to sys/mman.h
|
||
|
|
|
||
|
|
x86 added the flag (29f890d1050fc099f) for CET enabled.
|
||
|
|
|
||
|
|
Also update tst-mman-consts.py test.

(removed patch to keep alerting about kernel differences)

|

(adapted to missing __USE_MISC conditional upstream)
