Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

sh: Replace DEBUG_STACKOVERFLOW with STACK_DEBUG. STACK_DEBUG ties in to mcount in order to do function-granular stack overflow checks as opposed to lazily checking from IRQ context. As the default is nohz, the frequency of overflow checking is too irregular to catch much useful information, and so the mcount approach employed by sparc64 is adopted instead. This kills off the old check entirely from the do_IRQ() path and now adopts CONFIG_MCOUNT instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

sh: Add support for 4K stacks. This enables support for 4K stacks on SH. Currently this depends on DEBUG_KERNEL, but likely all boards will switch to this as the default in the future. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

sh: Disable 4kB stacks when using PAGE_SIZE_64KB. This combination triggers a divide by zero in kernel/fork.c when calculating the initial max_threads value: max_threads = mempages / (8 * THREAD_SIZE / PAGE_SIZE); Simply disable 4K stacks on 64kB PAGE_SIZE to work around this, as it's not a terribly useful combination to begin with.

sh: Decouple 4k and soft/hardirq stacks. While using separate IRQ stacks can cut down on stack consumption, many users can also use 4k stacks directly without the additional need of separate stacks for soft and hardirqs. With this split, we support the same rationale for 4KSTACKS as m68knommu, with the IRQSTACKS abstraction as per ppc64. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

sh: Flag IRQSTACKS as BROKEN for now. There still seems to be some stack corruption to sort out here, so flag this as BROKEN until this issue is sorted out. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

sh: Conditionalize the code dumper on CONFIG_DUMP_CODE. We don't really want this enabled by default, but it is still quite useful for debugging. So, make it conditional and leave it off by default. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

sh: dwarf unwinder support. This is a first cut at a generic DWARF unwinder for the kernel. It's still lacking DWARF64 support and the DWARF expression support hasn't been tested very well but it is generating proper stacktraces on SH for WARN_ON() and NULL dereferences.

sh: dwarf unwinder depends on SHcompact. Presently there's no SHmedia support plugged in for the dwarf unwinder. While it's trivial to provide an SHmedia version of dwarf_read_arch_reg(), the general sh64 case is more complicated in that the TLB miss handler uses a locked down set of registers for optimization (including the frame pointer) which we need for the unwind table generation. While freeing up the frame pointer for use in the TLB miss handler is reasonably straightforward, it's still more trouble than it's worth, so we simply restrict the unwinder to 32-bit for now.

sh: Enable skipping of bss on debug platforms for sh32 also. This enables the same functionality that sh64 has for sh32. When running on simulated hardware or via remote memory via the debug interface, memory is gauranteed to be zero on boot already, and skipping the zeroing of BSS has measurable boot time benefits.

sh: Decouple mcount from ftrace. This adds a general CONFIG_MCOUNT in order to permit mcount generation without ftrace support. This is primarily for allowing platforms to enable aggressive stack overflow checking without having to enable ftrace support. Based on the sparc64 implementation.
