avr32: Clean up and optimize the TLB operations
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>
