Cover letter [PATCH 00/10] arm64: Replace TLB invalidation preprocessor macros with C functions
Hi all,
I cooked this series following a complaint from Linus back in March about our range-based TLB invalidation macro after we fixed an over-invalidation bug thanks to incorrect handling of its arguments:
https://lore.kernel.org/all/CAHk-=wgiX0q0WCL+SFwVCYtG7JR3=2Rshse-5J3AO2Y4AgT7Jw@mail.gmail.com/
Once I started trying to rework the range macro into a C function, I spotted a few other opportunities for cleanup and so I've ended up with this series.
Testing and feedback welcome.
Cheers,
Will
