Re: [PATCH 7/7] Expand directly for single bit test

Hi, Andrew Thanks for this series of patches to improve do_store_flag. Unfortunately this specific patch in the series has caused a bootstrap failure on powerpc-aix. I bisected this failure to this specific patch. Note that I am building as 32 bit, so this could be a specific issue about bit
