[XTENSA] Add support for configurable registers and coprocessors
The Xtensa architecture allows to define custom instructions and registers. Registers that are bound to a coprocessor are only accessible if the corresponding enable bit is set, which allows to implement a 'lazy' context switch mechanism. Other registers needs to be saved and restore at the time of the context switch or during interrupt handling.
This patch adds support for these additional states:
- save and restore registers that are used by the compiler upon interrupt entry and exit. - context switch additional registers unbound to any coprocessor - 'lazy' context switch of registers bound to a coprocessor - ptrace interface to provide access to additional registers - update configuration files in include/asm-xtensa/variant-fsf

[XTENSA] Clean up elf-gregset.
Remove additional registers from the ELF gregset structure that are only used by the kernel or are not required or invalid in user-space. The ar registers are always aligned to a windowbase value of 0, and the WB register is always assumed to be 0. Increase the size of the structure to 128 entries. This will provide enough space in future.

[PATCH] Change panic_on_oops message to "Fatal exception"
Previously the message was "Fatal exception: panic_on_oops", as introduced in a recent patch whith removed a somewhat dangerous call to ssleep() in the panic_on_oops path. However, Paul Mackerras suggested that this was somewhat confusing, leadind people to believe that it was panic_on_oops that was the root cause of the fatal exception. On his suggestion, this patch changes the message to simply "Fatal exception". A suitable oops message should already have been displayed.

[PATCH] panic_on_oops: remove ssleep()
This patch is part of an effort to unify the panic_on_oops behaviour across all architectures that implement it.
It was pointed out to me by Andi Kleen that if an oops has occured in interrupt context, then calling sleep() in the oops path will only cause a panic, and that it would be really better for it not to be in the path at all.
This patch removes the ssleep() call and reworks the console message accordinly. I have a slght concern that the resulting console message is too long, feedback welcome.
For powerpc it also unifies the 32bit and 64bit behaviour.
Fror x86_64, this patch only updates the console message, as ssleep() is already not present.

xtensa: add show_stack_loglvl() Currently, the log-level of show_stack() depends on a platform realization. It creates situations where the headers are printed with lower log level or higher than the stacktrace (depending on a platform or user). Furthermore, it forces the logic decision from user to an architecture side. In result, some users as sysrq/kdb/etc are doing tricks with temporary rising console_loglevel while printing their messages. And in result it not only may print unwanted messages from other CPUs, but also omit printing at all in the unlucky case where the printk() was deferred. Introducing log-level parameter and KERN_UNSUPPRESSED [1] seems an easier approach than introducing more printk buffers. Also, it will consolidate printings with headers.

xtensa: add support for call0 ABI in userspace Provide a Kconfig choice to select whether only the default ABI, only call0 ABI or both are supported. The default for XEA2 is windowed, but it may change for XEA3. Call0 only runs userspace with PS.WOE disabled. Supporting both windowed and call0 ABIs is tricky, as there's no indication in the ELF binaries which ABI they use. So it is done by probing: each process is started with PS.WOE disabled, but the handler of an illegal instruction exception taken with PS.WOE retries faulting instruction after enabling PS.WOE. It must happen before any signal is delivered to the process, otherwise it may be delivered incorrectly. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

signal: Remove the task parameter from force_sig_fault As synchronous exceptions really only make sense against the current task (otherwise how are you synchronous) remove the task parameter from from force_sig_fault to make it explicit that is what is going on. The two known exceptions that deliver a synchronous exception to a stopped ptraced task have already been changed to force_sig_fault_to_task. The callers have been changed with the following emacs regular expression (with obvious variations on the architectures that take more arguments) to avoid typos: force_sig_fault[(]\([^,]+\)[,]\([^,]+\)[,]\([^,]+\)[,]\W+current[)] -> force_sig_fault(\1,\2,\3) Signed-off-by: "Eric W.
