SGI UV's uv_tlb.c driver has become rather hard to read, with overly large functions, non-standard coding style and (way) too long variable, constant and function names and non-obvious code flow sequences. This patch improves the readability and maintainability of the driver significantly, by doing the following strict code cleanups with no side effects: - Split long functions into shorter logical functions. - Shortened some variable and structure member names. - Added special functions for reads and writes of MMR regs with very long names. - Added the 'tunables' table to shortened tunables_write(). - Added the 'stat_description' table to shorten uv_ptc_proc_write(). - Pass fewer 'stat' arguments where it can be derived from the 'bcp' argument. - Function definitions consistent on one line, and inline in few (short) cases. - Moved some small structures and an atomic inline function to the header file. - Moved some local variables to the blocks where they are used. - Updated the copyright date. - Shortened uv_write_global_mmr64() etc. using some aliasing; no line breaks. Renamed many uv_.. functions that are not exported. - Aligned structure fields. [ note that not all structures are aligned the same way though; I'd like to keep the extensive commenting in some of them. ] - Shortened some long structure names. - Standard pass/fail exit from init_per_cpu() - Vertical alignment for mass initializations. - More separation between blocks of code. Tested on a 16-processor Altix UV. Signed-off-by:
