Hello, As per the recent discussion, the folowing patch removes the TIF_NOTIFY_RESUME flag from all processor architectures. The flag was not used except on IA-64 for the perfmon subsystem. For IA-64, the patch replaces the flag with a new dedicated TIF flag. This provides an extra low-order bit for the TIF flags. I tested the kernel compiles on i386,x86_64,mips,ia64,powerpc. The patch is relative to 2.6.22-rc2 but applies smoothly to 2.6.22-rc2-git3. Changelog: - remove unused TIF_NOTIFY_RESUME flag for all processor architectures. The flag was not used excecpt on IA-64 where the patch replaces it with TIF_PERFMON_WORK. signed-off-by: stephane eranian <eranian@xxxxxxxxxx> diff -urNp
