2008-05-21sparc64: Prevent stack backtrace false positives on trap frames.David S. Miller

2008-05-21sparc64: Fix stack tracing through trap frames.David S. Miller
The offset to the pt_regs area was wrong, so we weren't looking at the right location for the magic cookie. A trap frame is composed of a "struct sparc_stackf" then a "struct pt_regs", the code was using "struct reg_window" instead of "struct sparc_stackf". Signed-off-by: David S. Miller <davem@davemloft.net>
2008-05-21sparc64: Fix kernel thread stack termination.David S. Miller
Because of the silly way I set up the initial stack for new kernel threads, there is a loop at the top of the stack. To fix this, properly add another stack frame that is copied from the parent and terminate it in the child by setting the frame pointer in that frame to zero. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-05-20sparc64: Add global register dumping facility.David S. Miller
When a cpu really is stuck in the kernel, it can be often impossible to figure out which cpu is stuck where. The worst case is when the stuck cpu has interrupts disabled. Therefore, implement a global cpu state capture that uses SMP message interrupts which are not disabled by the normal IRQ enable/disable APIs of the kernel. As long as we can get a sysrq 'y' to the kernel, we can get a dump. Even if the console interrupt cpu is wedged, we can trigger it from userspace using /proc/sysrq-trigger The output is made compact so that this facility is more useful on high cpu count systems, which is where this facility will likely find itself the most useful :) Signed-off-by: David S.

2008-05-19[POWERPC] 4xx: Workaround for CHIP_11 ErrataJosh Boyer
The PowerPC 440EP, 440GR, 440EPx, and 440GRx chips have an issue that causes the PLB3-to-PLB4 bridge to wait indefinitely for transaction requests that cross the end-of-memory-range boundary. Since the DDR controller only returns the valid portion of a read request, the bridge will prevent other PLB masters from completing their transactions. This implements the recommended workaround for this errata for chips that use older versions of firmware that do not already handle it. The last 4KiB of memory are hidden from the kernel to prevent the problem transactions from occurring.

2008-05-19sh: Fix up restorer in debug_trap exception return path.Paul Mundt
There are a few different types of debug trap exceptions, though now that they are all going through a special jump table, the restorer needs to be unified as well. Presently this is falling through the ret_from_fork path, which more or less does the right thing on SH-3/4 whilst being completely unsuitable on MMU-less targets. Ultimately what we want here is a branch through the platform's restore_all directly, without worrying about the retval being clobbered. We can accomplish that through a branch to __restore_all directly, so switch it so we come back from the jump table and branch to the restorer. This fixes up a recursion in the nommu WARN_ON() path, as well as some other userspace nastiness where said recursion caused serious stack corruption. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
