| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some host controllers (such as SH7786) have overlapping regions that are fixed in hardware.

| * | | sh: Make the atomic functions safe for irqsoff tracingMatt Fleming2009-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The irqsoff tracer uses the atomic_* functions internally, but the implementations of those functions in arch/sh/include/asm/atomic-irq.h disable irqs to achieve atomicity. A continuous loop ensues where we disable interrupts, trace the interrupt disabling, call atomic_* functions, disable interrupts, trace the interrupt disabling, etc.. The simplest solution to all this is to just convert uses of local_irq_save()/local_irq_restore() the raw_* equivalents because the raw_* equivalents don't call trace_hardirqs_on()/trace_hardirqs_off().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Presently the earlytimer probe handles the clockevents driver, which requires that the clockevents driver be registered first. This bumps it up by 1 to include the clocksource device, which can be safely ignored if it doesn't exist, as we will simply error out on that path and defer to the jiffies clocksource.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These were handled through late_time_init due to kmalloc() and friends not being available earlier on previously. Now with slab caches being available much earlier, this is no longer necessary, and we can move the initialization up to an earlier point. One of the benefits with this is that printk times are available a bit earlier! Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | * | | sh: Fix dynamic ftrace's NOP action.Matt Fleming2009-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ftrace on sh handles nop'ing out trace function calls differently than other architectures. Instead of inserting NOP instructions in place of the call to the function tracer we branch over the call instructions and continue executing the main body of the function. This patch fixes a bug in the implementation of ftrace_modify_code() where we check that the old value of the code we're about to replace is an expected one. In the ftrace_make_call() code path ftrace_modify_code() was comparing the old instruction value with NOP instructions. The compare was failing because we never actually insert NOP instructions. It makes sense to just get rid of the NOP instructions in ftrace_nop and compare the old code with the address of the function body if we're expecting ftrace to have nop'd out the function trace call.

Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h, controlled by __WITH_KM_FENCE from each arch's kmap_types.h file. Would be nice to be able to add custom KM_types per arch, but I don't yet see a nice, clean way to do that. Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and 68k(tonyb). Note: avr32 should be able to remove KM_PTE2 (since it's not used) and then just use the generic kmap_types.h file. Get avr32 maintainer approval.

We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.
