Have you diffed the affected files between this patch and
csl-arm-branch?  If not, please do that.  The patch is certainly not OK
as is; for instance I see the ABI fix for WCHAR_TYPE is missing. 
Searching ChangeLog.csl-arm for "linux", I see about four other
relevant patches.

Fixing the missing space Joseph pointed out on csl-arm-branch would be
nice if you've got a chance.

You didn't mention if you'd run the testsuite on this.  If so, you
might want to also try running the compat testsuite against a
csl-arm-branch compiler.

IMO we want to get rid of H_W_I from that interface, but I'm not sure
how to do it without slowing down 32-bit HWI targets...
