2012-12-20UAPI: Fix up empty files in arch/cris/David Howells
Fix up three empty files in arch/cris/ by sticking placeholder comments in there to prevent the patch program from deleting them. I decided not to delete the arch-v*/Kbuild files as it's possibly someone might want to use them for genhdr-y lines in the future, but they could be deleted and the pointer lines removed from asm/Kbuild. The uapi/arch-v*/Kbuild files ought to be uneffected by such a change. asm/swab.h didn't have anything outside of __KERNEL__ so nothing appeared in uapi/asm/swab.h. The latter, however, is exported by Kbuild.asm. This needs to be applied after the CRIS UAPI disintegration patch.

git://git.infradead.org/users/dhowells/linux-headers Pull preparatory patches for user API disintegration from David Howells: "The patches herein prepare for the extraction of the Userspace API bits from the various header files named in the Kbuild files. New subdirectories are created under either include/uapi/ or arch/x/include/uapi/ that correspond to the subdirectory containing that file under include/ or arch/x/include/. The new subdirs under the uapi/ directory are populated with Kbuild files that mostly do nothing at this time. Further patches will disintegrate the headers in each original directory and fill in the Kbuild files as they do it. These patches also: (1) fix up #inclusions of "foo.h" rather than <foo.h>. (2) Remove some redundant #includes from the DRM code. (3) Make the kernel build infrastructure handle Kbuild files both in the old places and the new UAPI place that both specify headers to be exported. (4) Fix some kernel tools that #include kernel headers during their build. I have compile tested this with allyesconfig against x86_64, allmodconfig against i386 and a scattering of additional defconfigs of other arches.

2010-10-07Fix IRQ flag handling namingDavid Howells
Fix the IRQ flag handling naming. In linux/irqflags.h under one configuration, it maps: local_irq_enable() -> raw_local_irq_enable() local_irq_disable() -> raw_local_irq_disable() local_irq_save() -> raw_local_irq_save() ... and under the other configuration, it maps: raw_local_irq_enable() -> local_irq_enable() raw_local_irq_disable() -> local_irq_disable() raw_local_irq_save() -> local_irq_save() ... This is quite confusing. There should be one set of names expected of the arch, and this should be wrapped to give another set of names that are expected by users of this facility. Change this to have the arch provide: flags = arch_local_save_flags() flags = arch_local_irq_save() arch_local_irq_restore(flags) arch_local_irq_disable() arch_local_irq_enable() arch_irqs_disabled_flags(flags) arch_irqs_disabled() arch_safe_halt() Then linux/irqflags.h wraps these to provide: raw_local_save_flags(flags) raw_local_irq_save(flags) raw_local_irq_restore(flags) raw_local_irq_disable() raw_local_irq_enable() raw_irqs_disabled_flags(flags) raw_irqs_disabled() raw_safe_halt() with type checking on the flags 'arguments', and then wraps those to provide: local_save_flags(flags) local_irq_save(flags) local_irq_restore(flags) local_irq_disable() local_irq_enable() irqs_disabled_flags(flags) irqs_disabled() safe_halt() with tracing included if enabled. The arch functions can now all be inline functions rather than some of them having to be macros.

2010-03-12cris arch-v32: use generic ptrace_resume codeChristoph Hellwig
Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT, PTRACE_KILL and PTRACE_SINGLESTEP. This implies defining arch_has_single_step in <asm/ptrace.h> and implementing the user_enable_single_step and user_disable_single_step functions, which also causes the breakpoint information to be cleared on fork, which could be considered a bug fix. Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which it previously wasn't which is consistent with all architectures using the modern ptrace code. The way breakpoints are disabled is entirely inconsistent currently, I tried to make some sense of it, but I suspect all of the content of ptrace_disable should be moved into user_disable_single_step, this defintively needs some revisting as the current patch changes behaviour in not quite designed ways.

2009-12-14locking: Convert raw_spinlock to arch_spinlockThomas Gleixner
The raw_spin* namespace was taken by lockdep for the architecture specific implementations. raw_spin_* would be the ideal name space for the spinlocks which are not converted to sleeping locks in preempt-rt. Linus suggested to convert the raw_ to arch_ locks and cleanup the name space instead of using an artifical name like core_spin, atomic_spin or whatever No functional change.

2009-06-08CRIS: assignment/is equal confusionRoel Kluin
Somehow, the assignments of rw->lock got written as comparisons. The effect probably was that the read-write spinlocks never locked. However, since the locks are only used in CONFIG_SMP and SMP CRIS is experimental, it has never been identified as a problem.
