[PATCH 09/24] arm64: rename functions that reference compat term
From: Yury Norov <hidden>
Date: 2018-05-16 08:21:34
Also in:
linux-arch, linux-arm-kernel, linux-doc, lkml
Subsystem:
arm pmu profiling and debugging, arm64 port (aarch64 architecture), performance events subsystem, ptrace support, the rest · Maintainers:
Will Deacon, Mark Rutland, Catalin Marinas, Peter Zijlstra, Ingo Molnar, Arnaldo Carvalho de Melo, Namhyung Kim, Oleg Nesterov, Linus Torvalds
The ILP32 for ARM64 patch series introduces another 'compat' mode for arm64. So to avoid confusing, aarch32-only functions renamed in according to it.
