[RFC] cacheflush.2: Document different prototypes for different architectures
Hi Michael, Continuing with the changes in this thread: https://lore.kernel.org/linux-man/747d56e0-c102-ab40-add4-530a48a43...@gmx.de/T/#t I researched the architectures that have this syscall. I found some that clearly provide the syscall, and some that seem to have something, but I didn't find a definition in the kernel (i.e., ARM, MicroBlaze (glibc only)?)
