However that didn't take into account the fact that __fls() already already had different semantics in the kernel. Let's move the __fls() code into fls() function directly, and redefine __fls() with the appropriate semantics. While at it, bring a generic __fls() definition for pre ARMv5 too.

One of the things it does is to make READ_IMPLIES_EXEC be set in ->personality if we are running on a CPU that doesn't support the XN ("Execute Never") page table bit or if we are running a binary that needs an executable stack. This exposed a latent bug in ARM's asm/processor.h due to which we'll end up placing the stack at a very low address, where it will bump into the heap on any application that uses significant amount of stack or heap or both, causing many interesting crashes. Fix this by testing the ADDR_LIMIT_32BIT bit in ->personality instead of testing for equality against PER_LINUX_32BIT.

Gpios in PER domain aren't capable to generate wake-up if PER domain is in sleep state. For this iopad wake-up should be used and needed pad configuration should be done.

The calls addressed by this patch are the simple ones to get and set values ... for code that's in mainline, including the implementations of those calls. Except for the declarations and definitions of those calls, all of these changes were performed by a simple SED script. Plus, a few "if() set() else set()" branches were merged by hand.

Note that because gpio_direction_output() includes the initial value, this change isn't quite transparent. - For the call sites which defined an initial value either before or after setting the direction, that value was used. When that value was previously assigned afterwards, this could eliminate a brief output glitch ... and possibly change behavior. In a few cases (LCDs) several values were assigned together ... those were re-arranged to match the explicit sequence provided. - Some call sites didn't define such a value; so I chose an initial "off/reset" value that seemed to default to "off". In short, files touched by this patch might notice some small changes in startup behavior (with trivial fixes).

This is the usual case for dynamic tick-enabled kernels. Simulation data indicate that skipping the read that occurs as part of the write should save at least 300-320 ns for each GPTIMER1 timer reprogram. (This assumes L4-Wakeup is at 19MHz and GPTIMER write posting is enabled.) Skipping the write itself probably won't have much impact since it should be posted on the OCP interconnect. Tested on 2430SDP and 3430SDP.
