Subject: mips: Consolidate INTERNAL_VSYSCALL_CALL
X-Git-Tag: changelog-ends-here~57
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=7c3eed786021ede69394fe371c9e7c8bd603f5a8;p=thirdparty%2Fglibc.git

mips: Consolidate INTERNAL_VSYSCALL_CALL

This patch consolidates the mips, mips64, and mips64-n32
INTERNAL_VSYSCALL_CALL on a single implementation.

No semantic changes. I checked against a build for mips-linux-gnu,
mips64-linux-gnu, and mips64-n32-linux-gnu.

	* sysdeps/unix/sysv/linux/mips/mips32/sysdep.h
	(INTERNAL_VSYSCALL_CALL): Remove.
	* sysdeps/unix/sysv/linux/mips/mips64/n32/sysdep.h
	(INTERNAL_VSYSCALL_CALL): Likewise.
	* sysdeps/unix/sysv/linux/mips/mips64/n64/sysdep.h
	(INTERNAL_VSYSCALL_CALL): Likewise.
	* sysdeps/unix/sysv/linux/mips/sysdep.h (INTERNAL_VSYSCALL_CALL):
	New macro.
