Subject: Remove __ASSUME_GETCPU_SYSCALL.
X-Git-Tag: glibc-2.26~543
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1278ed2c645cc31fc5a71febf309bbec9a9d9f90;p=thirdparty%2Fglibc.git

Remove __ASSUME_GETCPU_SYSCALL.

This patch removes the definition of __ASSUME_GETCPU_SYSCALL.  In fact
this macro is unused, probably since:

    Consolidate sched_getcpu

so it could have been removed even without the move to 3.2 as minimum
kernel version on x86_64.

Tested for x86_64.
