Subject: [PATCH] Revert "MIPS: Provide correct siginfo_t.si_stime"
This reverts commit 8cb48fe169dd682b6c29a3b7ef18333e4f577890.
UAPI headers cannot use "uapi/" in their paths by design -- when they're
installed, they do not have the uapi/ prefix. Otherwise doing so breaks
userland badly:
$ printf '#include <stddef.h>\n#include <linux/signal.h>\n' > test.c
$ mips64-unknown-linux-gnu-gcc -c test.c
In file included from
/usr/mips64-unknown-linux-gnu/usr/include/linux/signal.h:5:0,
from test.c:2:
/usr/mips64-unknown-linux-gnu/usr/include/asm/siginfo.h:31:38: fatal error:
uapi/asm-generic/siginfo.h: No such file or directory
compilation terminated.
