ARM: 5759/1: Add register information of threads to coredump

2009-10-14T09:33:05+00:00

Defines ELF_CORE_COPY_TASK_REGS so that CPU register information
of every thread is included in coredump. Without this, only the faulting
thread is coredumped.

[ARM] idle: clean up pm_idle calling, obey hlt_counter

2009-06-22T21:34:55+00:00

pm_idle is used by infrastructure (eg, cpuidle) which expects architectures
to call it in a certain way.  Arrange for ARM to follow x86's lead on this
and call pm_idle() with interrupts already disabled.  However, we expect
pm_idle() to enable interrupts before it returns.

Also, OMAP wants to be able to disable hlt-ing, so allow hlt_counter to
prevent all calls to pm_idle.

[ARM] 5559/1: Limit the stack unwinding caused by a kthread exit

2009-06-19T15:44:23+00:00

When a kthread function returns, it branches to do_exit(). However, the
unwinding information isn't valid anymore and any stack trace caused by
do_exit() may be incorrect. This patch adds a kernel_thread_exit()
function and annotated with '.cantunwind' so that the unwinder stops
when reaching it.

Add core support for ARMv6/v7 big-endian

2009-05-30T13:00:18+00:00

Starting with ARMv6, the CPUs support the BE-8 variant of big-endian
(byte-invariant). This patch adds the core support:

- setting of the BE-8 mode via the CPSR.E register for both kernel and
  user threads
- big-endian page table walking
- REV used to rotate instructions read from memory during fault
  processing as they are still little-endian format
- Kconfig and Makefile support for BE-8. The --be8 option must be passed
  to the final linking stage to convert the instructions to
  little-endian

[ARM] pass reboot command line to arch_reset()

2009-03-19T16:20:24+00:00

OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

[ARM] 5382/1: unwind: Reorganise the stacktrace support

2009-02-12T13:21:17+00:00

This patch changes the walk_stacktrace and its callers for easier
integration of stack unwinding. The arch/arm/kernel/stacktrace.h file is
also moved to arch/arm/include/asm/stacktrace.h.

[ARM] remove pc_pointer()

2008-09-06T09:35:51+00:00

pc_pointer() was a function to mask the PC for 26-bit ARMs, which
we no longer support.  Remove it.
