Thank you for the report, good catch!
Those are not wrong values, just have not been updated to the current values..
For example, with regard to mips (including mips64?), it was changed at v2.6.23:
$ git grep '^#define TIF_SIGPENDING' v2.6.22:include/asm-mips
v2.6.22:include/asm-mips:thread_info.h:#define TIF_SIGPENDING 2 /* signal pending */
$ git grep '^#define TIF_SIGPENDING' v2.6.23:include/asm-mips
v2.6.23:include/asm-mips:thread_info.h:#define TIF_SIGPENDING 1 /* signal pending */
As far as I've checked, those were changed respectively:
ARM 2 -> 0 at v2.6.23
MIPS 2 -> 1 at v2.6.23
MIPS64 2 -> 1 at v2.6.23
PPC 2 -> 1 at v2.6.23
IA64 1 -> 0 at v2.6.23
PPC64 2 -> 1 at v2.6.23
S390 2 -> 1 at v3.16
S390X 2 -> 1 at v3.16
So how about something like this?
#define TIF_SIGPENDING (THIS_KERNEL_VERSION >= LINUX(2,6,23) ? 0 : 2)
Thanks,
