This kernel gives a build failure on ppc64le:

 arch/powerpc/kernel/prom.c:170:25: error: 'PPC_FEATURE2_HTM_NOSC_COMP' undeclared here (not in a function)
   PPC_FEATURE2_HTM_COMP|PPC_FEATURE2_HTM_NOSC_COMP, 22, 0, 0},
                         ^

It's due to the commit f49eb503f0f9ab66874a81992b14249a1c59b6ad
    powerpc: Update TM user feature bits in scan_features()

FYI, the macro referred there is defined in the upstream commit
b4b56f9ecab40f3b4ef53e130c9f6663be491894
    powerpc/tm: Abort syscalls in active transactions

Please revert the relevant commit, or fix it properly.


thanks,

Takashi
