Subject: [PATCH v4 00/36] Hexagon: Add support for Qualcomm Hexagon architecture
This is the fourth version of the patchset to the Linux kernel to support
the Qualcomm Hexagon architecture. These patches have been organized like
previously in a somewhat logically grouped fashion.
A brief summary of changes from the last patchset:
* changes associated with removing pt_regs from user_context
* removal of arch-specific ptrace cases; use generic ptrace_request
* turn on CONFIG_ARCH_TRACEHOOKS
* removal of deprecated sigframe
* add magic values for libgcc signal stack unwinding
* add memory clobber to IO inlines
* use generic show_interrupts
* minor timer cleanup
* minor SMP IPI cleanup
* moved local_irq_enable in do_page_fault
These patches are available on Code Aurora:
https://www.codeaurora.org/patches/quic/hlk/hexagon-linux-20110916/
Once again, thanks to everyone for their feedback!
