Due to 'powerpc/tm: Disable IRQ in tm_recheckpoint' which uses the above define
without defining it. TEXASR_FS is defined with commit e4e381215 (KVM: PPC: Book3S
HV: Add transactional memory support) upstream.
Argh, bugger.
The below should fix both trees. It's just the #define from upstream
e4e38121507a27d2ccc4b28d9e7fc4818a12c44c (we don't want the rest of that patch
in stable as it's not a fix).
It would probably be better to merge it into the other patch, as it is really
part of the back-port (and bisect would be broken otherwise for the affected
images).
