[PATCH 0/3] Better transaction abort reports

[David Sterba <dsterba@suse.cz>]

Hi,

patch #1 moves the WARN at transaction abort time to the callsite (via macro).
That way we get the exact location of the error and not the common location.
This is supposed to help debugging and screening report, but the change comes
at some cost and increases the resulting asm code.

I vote for better error reports, the .text grows all the time anyway. Patch #2
adds some compiler hints so the error blocks are likely to be put out of the
hot paths.
