m32r: define __fls

2009-01-03T05:46:54Z

Like fls, but can't be handed 0 and returns the bit number. Signed-off-by: Rusty Russell

forbid asm/bitops.h direct inclusion

2007-10-19T18:53:41Z

forbid asm/bitops.h direct inclusion Because of compile errors that may occur after bit changes if asm/bitops.h is included directly without e.g. linux/kernel.h which includes linux/bitops.h, forbid direct inclusion of asm/bitops.h.

bitops: introduce lock ops

2007-10-18T21:37:29Z

Introduce test_and_set_bit_lock / clear_bit_unlock bitops with lock semantics. Convert all architectures to use the generic implementation.

[PATCH] bitops: use non atomic operations for minix__bit() and ext2__bit()

2006-03-26T16:57:10Z

Bitmap functions for the minix filesystem and the ext2 filesystem except ext2_set_bit_atomic() and ext2_clear_bit_atomic() do not require the atomic guarantees. But these are defined by using atomic bit operations on several architectures. (cris, frv, h8300, ia64, m32r, m68k, m68knommu, mips, s390, sh, sh64, sparc, sparc64, v850, and xtensa) This patch switches to non atomic bit operation.

[PATCH] m32r: Make kernel headers for mutual exclusion

2005-01-03T13:04:08Z

Here is a patch to update kernel headers for mutual exclusion, atomic.h, bitops.h and semaphore.h of m32r. This patch is for making these headers publishable to userland. * include/asm-m32r/assembler.h (M32R_LOCK, M32R_UNLOCK): Define M32R_LOCK and M32R_UNLOCK macros. For SMP configuration, these macros are expanded to m32r's LOCK and UNLOCK instructions. While, for UP configuration, these are simply expanded to m32r's LD(load) and ST(store) instructions, respectively. * include/asm-m32r/atomic.h, include/asm-m32r/bitops.h, include/asm-m32r/semaphore.h: - Change macros from LOAD and STORE to M32R_LOCK and M32R_UNLOCK, respectively. It is because LOAD and STORE are too generic words. - Change inline to __inline__. Retrieve __inline__ modifiers for functions which are placed outside of __KERNEL__ region in these headers, because those functions might be included and used from ISO C program in userland. Currently, it seems that these headers are allowed to be included from userland. Indeed, they are kernel stuff, but these headers provide useful definitions and functions even for userland applications, I think.

[PATCH] m32r: change to use temporary register variables

2004-10-03T02:17:47Z

I made a patch to upgrade some header files for m32r. - Change to use temporary register variables allocated by the compiler, instead of fiexd register varialbes. - Change __inline__ to inline. Signed-off-by: Hirokazu Takata Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
