i apologize for the mistake.
Of the 15 architectures that were subjected to setup_irq() cleanup,
i had done build & boot test only on ARM & x86_64, at the minimum i
should have informed you upfront in the previous mail (in v2 & v1 it was
mentioned in cover letter). i was trying to rely on kbuild test robot
for help in building other arch's. Seems it is randomly selecting
patches, since some of the issues were present in v2 & v1 as well and
no error report were recieved on v1 & v2 MIPS patch.
kbuild test robot had provided the way to create mips cross compiler
as well as the config. The build error has been fixed that were
spotted by you as well kbuild test robot, also there were a few more
issues including other build error. v4 that resolves all these
has been sent.
All the files that has been modified has been verifed to generate
object files w/o error or warnings. w/ the test robot provided config,
not all changes in my patch were being compiled, so i had to manually
select each machines one at a time to verify every change. Also i
couldn't build 3 machines (msp71xx, loongson64 & bcm63xx) even w/o my
changes. Those i had to find out defconfig's that can make those
changes build, then they also could be verified.
Sorry for the trouble, please let me know if further issues.
For your reference, diff between v4 & v3 below,
Regards
afzal
