The cris implementation of sys_pipe only differs from the generic one
by taking the BKL before calling do_pipe which isn't not nessecary.
Just kill the cris implementation and use the generic one.

Semaphores are no longer performance-critical, so a generic C
implementation is better for maintainability, debuggability and
extensibility. Thanks to Peter Zijlstra for fixing the lockdep
warning. Thanks to Harvey Harrison for pointing out that the
unlikely() was unnecessary.

- Collect extern declarations at top of file.
- Change raw_printk to printk, use oops_in_progress instead.
- Fix formatting and whitespace.
- Allow the watchdog to be disabled during oops.
This patchset adds a flags variable to reserve_bootmem() and uses the
BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions
between crashkernel area and already used memory.
This patch:
Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE.
If that flag is set, the function returns with -EBUSY if the memory already
has been reserved in the past. This is to avoid conflicts.
Because that code runs before SMP initialisation, there's no race condition
inside reserve_bootmem_core().

- Remove debug print.
- Change #if to #ifdef to avoid compile time warning if CONFIG_PROFILING
isn't set.
- Number of parameters to profile_tick has changed, drop the regs parameter.

Corrects compile errors and the following:
- Remove oldset parameter from do_signal and do_notify_resume.
- Modified to fit new consolidated IRQ handling code.
- Reverse check order between external nmi and watchdog nmi to avoid false
watchdog oops in case of a glitch on the nmi pin.
- Return from an pin-generated NMI the same way as for other interrupts.
- Moved blocking of ethernet rx/tx irq from ethernet interrupt handler to
low-level asm interrupt handlers. Fixed in the multiple interrupt
handler also.
- Add space for thread local storage in thread_info struct.
- Add NO_DMA to Kconfig, and include arch specific Kconfig using arch
independent path. Include subsystem Kconfigs for pcmcia, usb, i2c,
rtc and pci.

All asm/ipc.h files do only #include <asm-generic/ipc.h>.
This patch therefore removes all include/asm-*/ipc.h files and moves the
contents of include/asm-generic/ipc.h to include/linux/ipc.h.

Many struct file_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data. In addition it'll catch accidental writes at compile time to
these shared resources.
