2011-12-18x86: Convert per-cpu counter icr_read_retry_count into a member of irq_statFernando Luis Vazquez Cao
LAPIC related statistics are grouped inside the per-cpu structure irq_stat, so there is no need for icr_read_retry_count to be a standalone per-cpu variable. This patch moves icr_read_retry_count to where it belongs.

gcc noticed (when using -Wempty-body) that our use of lock_cmos() and unlock_cmos() in arch/x86/include/asm/mach_traps.h is potentially problematic : arch/x86/include/asm/mach_traps.h:32:15: warning: suggest braces around empty body in an ¡else¢ statement [-Wempty-body] arch/x86/include/asm/mach_traps.h:40:16: warning: suggest braces around empty body in an ¡else¢ statement [-Wempty-body] Let's just use the standard 'do {} while (0)' solution.

2011-12-16ARM: OMAP2+: hwmod: Add a new flag to handle hwmods left enabled at initRajendra Nayak
An hwmod with a 'HWMOD_INIT_NO_IDLE' flag set, is left in enabled state by the hwmod framework post the initial setup. Once a real user of the device (a driver) tries to enable it at a later point, the hwmod framework throws a WARN() about the device being already in enabled state. Fix this by introducing a new internal flag '_HWMOD_SKIP_ENABLE' to identify such devices/hwmods. When the device/hwmod is requested to be enabled (the first time) by its driver/user, nothing except the mux-enable is needed. The mux data is board specific and is unavailable during initial enable() of the device, done by the framework as part of setup(). A good example of a such a device is an UART used as debug console. The UART module needs to be kept enabled through the boot, until the UART driver takes control of it, for debug prints to appear on the console.

2011-12-16ARM: OMAP: hwmod: add support for selecting mpu_irq for each wakeup padTero Kristo
By default all registered pads will trigger mpu_irqs[0]. Now there is an API for selecting used mpu_irq on pad basis, which can be used to trigger different irq handlers for different pads in the same hwmod. Each pad that requires its interrupt to be re-routed this way must have a separate call to omap_hwmod_pad_route_irq(hwmod, pad, irq).
