hey Vitaliy/Ola,
The fixes for CVE-2010-0307 remove the TIF_ABI_PENDING bit from
arch-specific code. Since this #define no longer exists, our openvz
patch needs to be updated to not reference it.
It looks as though openvz only references to clear all arch-specific
flags, so I prepared the following fix. Please let me know if you see
any problem with it.
This applies after the following list of commits:
- 221af7f87 ("Split 'flush_old_exec' into two functions")
- 05d43ed8a ("x86: get rid of the insane TIF_ABI_PENDING bit")
- 7ab02af42 ("Fix 'flush_old_exec()/setup_new_exec()' split")
- 94f28da84 ("powerpc: TIF_ABI_PENDING bit removal")
