For some reason, the LDLAT extra reg definition for snb_ep showed up as duplicate in the snb table. This patch moves the definition of LDLAT back into the snb_ep table. Thanks to Don Zickus for tracking this one down.

I stupidly missed that boot_init_stack_canary() must be inlined from a function which never returns, but I put that call into arch_cpu_idle_prepare() which of course returns. I pondered to play tricks with arch_cpu_idle_prepare() first, but then I noticed, that the other archs which have implemented the stackprotector (ARM and SH) do not initialize the canary for the non-boot cpus. So I decided to move the boot_init_stack_canary() call into cpu_startup_entry() ifdeffed with an CONFIG_X86 for now. This #ifdef is just a temporary measure as I don't want to inflict the boot_init_stack_canary() call on ARM and SH that late in the cycle. I'll queue a patch for 3.11 which removes the #ifdef if the ARM/SH maintainers have no objection.

So it will find the lower bits of pmd set and the pmd_bad check throws error. Infact the current code will never take the free_hugepd_range call at all because it will clear the pmd if it find a hugepd pointer. Fix this by clearing bad pmd only if it is not a hugepd pointer.

Moreover, without this patch, when the "ticker" timer triggers timer_cs_read via tick_periodic it reads the value of the usual timer it can get an wrapped timer value without timer_cs_internal_counter having been updated leading to the clock going backwards. This effectively hangs one cpu that gets stuck in update_wall_time with an offset slightly smaller than 0xffffffffffffffff.

This finally fixes the kernel panic when running cat /proc/kpageflags /proc/kpagecount. Theoretically this patch now limits the number of physical memory ranges to 127 instead of 254, but currently we have MAX_PHYSMEM_RANGES hardcoded to 8 which is sufficient for all existing parisc machines.

In machine_shutdown(), replace the call to smp_send_stop() with a call to disable_nonboot_cpus(). This completely disables all but one CPU, thus satisfying the requirement that only a single CPU be active for kexec. Adjust Kconfig dependencies for this change. In machine_halt()/power_off()/restart(), call smp_send_stop() directly, rather than via machine_shutdown(); these functions don't need to completely de-activate all CPUs using hotplug, but rather just quiesce them. Remove smp_kill_cpus(), and its call from smp_send_stop(). smp_kill_cpus() was indirectly calling smp_ops.cpu_kill() without calling smp_ops.cpu_die() on the target CPUs first. At least some implementations of smp_ops had issues with this; it caused cpu_kill() to hang on Tegra, for example. Since smp_send_stop() is only used for shutdown, halt, and power-off, there is no need to attempt any kind of CPU hotplug here. Adjust Kconfig to reflect that machine_shutdown() (and hence kexec) relies upon disable_nonboot_cpus(). However, this alone doesn't guarantee that hotplug will work, or even that hotplug is implemented for a particular piece of HW that a multi-platform zImage runs on. Hence, add error-checking to machine_kexec() to determine whether it did work.

Otherwise, flush the kernel cache lines directly.

Fixes the AM33xx UART2. Also fixes some CCF-related breakage on OMAP36xx/37xx, affecting DSS at the very least. Basic test logs for this branch are here: http://www.pwsan.com/omap/testlogs/fixes_b_v3.10-rc/20130606093449/

However, looking at cclock3xxx_data.c, all concerned clock have parent defined as clk_divider. Fix the function to use clk_divider. Tested with 3.9 on dm3730.

This patch fixes this by making the UART2 hwmod structure to a new structure that lists the EDMA channels to be used by the UART2.

The PWM capability property is missing from the node definitions of couple of timers. Add ti,timer-pwm attribute for timer 5, 6, 8 and 11.

However these only fixed legacy boot and not DT boot. For DT boot, the default mux values need to be set properly in DT. Special thanks to Nishanth Menon for the review and catching some major flaws in earlier versions. Tested on OMAP4430/Panda and OMAP4460/Panda-ES.

Turns out we still need to idle iva2 as otherwise iva2_pwrdm will stay on and block deeper idle states. It seems that the only part of the reset that may not be needed is the setting of the iva2 boot mode to idle. But as that register seems to be there and is harmless if no iva2 is on the SoC, it's probably safest to do the complete reset. Acked-by: Mark A.
