Works for me:
$ git pull
Already up-to-date.
$ git log --oneline -1
ec44445 target-arm: Set Invalid flag for NaN in float-to-int conversions
$ wget -O perfcounters.patch http://patchwork.ozlabs.org/patch/92423/mbox/
$ git am perfcounters.patch
Applying: target-arm: Minimal implementation of performance counters
$

Looking at your .rej file it seems to have lost the hardcoded tab
characters[*] that are in the patch; I suspect something in your mailer
is turning them back into spaces. Try downloading the patch from
patchwork instead.

[*] the tab-indents are in the existing code, the patch is removing
them for the lines it touches
