Revision 05d43ed8a89c159ff641d472f970e3f1baa66318 authored by H. Peter Anvin on 29 January 2010, 06:14:43 UTC, committed by Linus Torvalds on 29 January 2010, 16:22:01 UTC 
x86: get rid of the insane TIF_ABI_PENDING bit
 
Now that the previous commit made it possible to do the personality
setting at the point of no return, we do just that for ELF binaries.
And suddenly all the reasons for that insane TIF_ABI_PENDING bit go
away, and we can just make SET_PERSONALITY() just do the obvious thing
for a 32-bit compat process.

Everything becomes much more straightforward this way.
