linux-alpha, linux-arch, linux-arm-kernel, linux-fsdevel, linux-m68k, linux-mips, linux-mm, linux-riscv, linux-sh, linux-um, lkml, sparclinux
Subsystem:
generic include/asm header files, mmu gather and tlb invalidation, the rest, user-mode linux (uml), x86 architecture (32-bit and 64-bit) · Maintainers:
Arnd Bergmann, Will Deacon, "Aneesh Kumar K.V", Andrew Morton, Nick Piggin, Peter Zijlstra, Linus Torvalds, Richard Weinberger, Anton Ivanov, Johannes Berg, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen
This seems to lead to some crazy include loops when using asm-generic/cacheflush.h on more architectures, so leave it to the arch header for now.
