The e200 core is a Book-E core (similar to e500) that has a unified L1 cache and is not cache coherent on the bus. The e200 core also adds a separate exception level for debug exceptions. Part of this patch helps to cleanup a few cases that are true for all Freescale Book-E parts, not just e500.

I8K: Change to use stock dmi infrastructure instead of homegrown parsing code. The driver now requires box's DMI data to match list of supported models so driver can be safely compiled-in by default without fear of it poking into random SMM BIOS code.

This patch adds support for Dynamic Tick Timer for ARM. Dynamic Tick is also known as VST (Variable Scheduling Timeouts). Dynamic Tick has been in use in the OMAP tree since last October. The patch is not intrusive, and does not do anything unless CONFIG_NO_IDLE_HZ is defined. This patch has the following fixed based on comments from RMK: - Time is updated before calling interrupt handlers. - Added new interrupt flag SA_TIMER to avoid duplicate timer interrupts - Moved struct dyn_tick_timer to time.h until we at some point probably have an arch independent dyn-tick.h - Cleaned up testing for DYN_TICK_ENABLED in irq.c I've cleaned up this patch to fix some remaining issues: - Call the timer tick handler with irqs disabled, as it would be from a normal interrupt - if we have a dyn_tick, we better implement all methods. - generic timer_dyn_reprogram() call, to be called before sleeping - added command line option - "dyntick=" to allow boot-time control of this feature -- rmk Signed-off-by: Tony Lindgren Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Patch from Lennert Buytenhek The later ixp2000 models don't need the PCI I/O workaround that we currently perform. Add a config option to disable the workaround, and panic on boot if a kernel without the workaround is booted on a buggy chip. As only pre-production ixp2000s need the workaround, the default is for it not to be configured in.

Patch from Lennert Buytenhek The ixp2000 gpio cleanup broke the ixdp2800 build as it moved some gpio-related functions from arch/platform.h to arch/gpio.h and the ixdp2x00 support code used those functions but didn't include the latter header file.

Patch from Catalin Marinas cpu_v6_set_pte() sets the kernel access rights to r/o for user pages (L_PTE_USER) when neither L_PTE_WRITE nor L_PTE_DIRTY are set.

Once the jprobe instrumented function returns, it executes a jprobe_break which is a break instruction with __IA64_JPROBE_BREAK value.

The current Kprobes when patching the original instruction with the break instruction tries to retain the original qualifying predicate(qp), however for cmp.crel.ctype where ctype == unc, which is a special instruction always needs to be executed irrespective of qp. Hence, if the instruction we are patching is of this type, then we should not copy the original qp to the break instruction, this is because we always want the break fault to happen so that we can emulate the instruction.

Fix a bug where a kprobe still fires when the instruction is predicated off. So given the p6=0, and we have an instruction like: (p6) move loc1=0 we should not be triggering the kprobe.

A cleanup of the ia64 kprobes implementation such that all of the bundle manipulation logic is concentrated in arch_prepare_kprobe(). With the current design for kprobes, the arch specific code only has a chance to return failure inside the arch_prepare_kprobe() function. This patch moves all of the work that was happening in arch_copy_kprobe() and most of the work that was happening in arch_arm_kprobe() into arch_prepare_kprobe(). By doing this we can add further robustness checks in arch_arm_kprobe() and refuse to insert kprobes that will cause problems.
