pm_idle is used by infrastructure (eg, cpuidle) which expects architectures to call it in a certain way. Arrange for ARM to follow x86's lead on this and call pm_idle() with interrupts already disabled. However, we expect pm_idle() to enable interrupts before it returns. Also, OMAP wants to be able to disable hlt-ing, so allow hlt_counter to prevent all calls to pm_idle. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

This allows the callers to now pass down the full set of FAULT_FLAG_xyz flags to handle_mm_fault(). All callers have been (mechanically) converted to the new calling convention, there's almost certainly room for architectures to clean up their code and then add FAULT_FLAG_RETRY when that support is added.

Correspondence with the TI OMAP hardware team indicates that SDRC_DLLA_CTRL.FIXEDDELAY should be initialized to 0x0f. This number was apparently derived from process validation. This is only used when the SDRC DLL is unlocked (e.g., SDRC clock frequency less than 83MHz). Signed-off-by: NPaul Walmsley <paul@pwsan.com>

Program the SDRC_MR_0 register as well during SDRC clock changes. This register allows selection of the memory CAS latency. Some SDRAM chips, such as the Qimonda HYB18M512160AF6, have a lower CAS latency at lower clock rates. Signed-off-by: NPaul Walmsley <paul@pwsan.com>

When changing the SDRAM clock from 166MHz to 83MHz via the CORE DPLL M2 divider, add a short delay before returning to SDRAM to allow the SDRC time to stabilize. Without this delay, the system is prone to random panics upon re-entering SDRAM. This time delay varies based on MPU frequency. At 500MHz MPU frequency at room temperature, 64 loops seems to work okay; so add another 32 loops for environmental and process variation. Signed-off-by: NPaul Walmsley <paul@pwsan.com>

On the OMAP3, initialize SDRC timings when the kernel boots. This ensures that the kernel is running with known, optimized SDRC timings, rather than whatever was configured by the bootloader. Signed-off-by: NPaul Walmsley <paul@pwsan.com>

When a kthread function returns, it branches to do_exit(). However, the unwinding information isn't valid anymore and any stack trace caused by do_exit() may be incorrect. This patch adds a kernel_thread_exit() function and annotated with '.cantunwind' so that the unwinder stops when reaching it.
