bcmdhd: Reduce rx_wakelock
pyramid: Add sysfs switch for basic color control

 The sysfs switch allows switching between the old color configuration
 and the new one. Sysfs switch is located at
 /sys/module/mdp/parameters/mdp_gamma_cooler_colors. The cooler color
 profile is disabled by default. The sysfs switch can be written to
 on-the-go; turn the screen off and on to apply the new color profile.

tracing/syscalls: Fix perf syscall tracing when syscall_nr == -1

syscall_get_nr can return -1 in the case that the task is not executing
a system call.

This patch fixes perf_syscall_{enter,exit} to check that the syscall
number is valid before using it as an index into a bitmap.
