This is an implementation of a suggestion made by Chris Torek: -------------------- Something else I noticed in passing: the EX and EX_LD/EX_ST macros scattered throughout the various .S files make a fair bit of .fixup code, all of which does the same thing. At the cost of one symbol in copy_in_user.S, you could just have one common two-instruction retl-and-mov-1 fixup that they all share. -------------------- The following is with a defconfig build: text data bss dec hex filename 3972767 344024 584449 4901240 4ac978 vmlinux.orig 39688877 344024 584449 4897360 4aba50 vmlinux Signed-off-by:

The removed version with the loop registers saved on the stack was originally intended to workaround the missing toolchain support for LoopReg Clobbers. Since our toolchain now supports these there is no point in keeping this workaround. And since we don't touch LoopRegs anymore we're no longer subject for ANOMALY_05000312. Signed-off-by:

use a do...while loop rather than a for loop to get slightly better optimization and to avoid gcc "may be used uninitialized" warnings ... we know that the [id]cplb_nr_bounds variables will never be 0, so this is OK Signed-off-by:

when requesting a GPIO for the first time, the POLAR setting is not set to a sane state. this can lead to indeterminate behavior that cannot be resolved without an explicit write to the Blackfin port POLAR register. when requesting a GPIO for the first time via gpio_request(), the POLAR setting for the GPIO in question should be set to sane state. this should occur if the GPIO has not been allocated in any other way. some examples: - when doing something like "request_irq(); gpio_request();" on the same GPIO, the POLAR setting should not be reset. - when doing "gpio_request(); gpio_request();" on the same GPIO, the POLAR setting should be reset only the first time and not the second.
