This and the following patches aim to optimize the code dealing with page tables and TLB operations. Each patch reduces the time it takes to gzip a 16 MB file slightly, but I expect things like fork() and mmap() will improve somewhat more. This patch deals with the low-level TLB operations: * Remove unused _TLBEHI_I define * Use gcc builtins instead of inline assembly * Remove a few unnecessary pipeline flushes and nops * Introduce NR_TLB_ENTRIES define and use it instead of hardcoding it to 32 a few places throughout the code. * Use sysreg bitops instead of hardcoded shifts and masks * Make a few needlessly global functions static Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com> |
