[v2,01/12] termios: Define TIOCSER_TEMT with __USE_MISC (BZ#17783)
Commit Message
This patch defines TIOCSER_TEMT on all architectures using the __USE_MISC
guards similar to BZ#17782 fix. Latest Linux UAPI defines TIOCSER_TEMT
with the same value for all architectures, so it is safe to use the value
as default for all ABIs.
Checked on x86_64linux-gnu and build against sparc64-linux-gnu and
powerpc64le-linux-gnu.
* sysdeps/unix/sysv/linux/bits/termios.h [__USE_MISC] (TIOCSER_TEMT):
Define.
* sysdeps/unix/sysv/linux/powerpc/bits/termios.h [__USE_MISC]
(TIOCSER_TEMT): Likewise.
* sysdeps/unix/sysv/linux/sparc/bits/termios.h [__USE_MISC]
(TEOCSER_TEMT): Likewise.
