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. Signed-off-by:

- Use kmalloc for m32r stacks (cf. changeset 1.1046.533.10) - Update for CONFIG_DEBUG_STACK_USAGE This modification was taken from include/asm-i386/thread_info.h. Signed-off-by:

- Use THREAD_SIZE for __ASSEMBLY__ portion. - Update comments. - Fix a typo: user-thead --> user-thread. NOTE: Now there are two THREAD_SIZE definitions in the following patch, one is in C part and the other is in __ASSEMBLY__ part. I'm going to consolidate these THREAD_SIZE definitions. So, I have to change PAGE_SIZE definition of include/asm-m32r/page.h to be includable into asm portion... Signed-off-by:

This patch updates ptrace.c to support multithread debugging. So far, only one breakpoint's location was kept by kernel, however, in the multithreaded application's debug, it is required to kept multi-point breakpoint locations by kernel. In this implementation, maximum number of MAX_TRAPS(=10 (by default)) breakpoint's information will be kept in the "debug_trap" member of the thread_struct for each thread. * include/asm-m32r/processor.h: Modify debug_trap struct to keep multipoint breakpoint locations for multithread debugging. * arch/m32r/kernel/ptrace.c: - Update to support multithread debugging. - Remove unused functions, withdraw_debug_trap_for_signal() and embed_debug_trap_for_signal().

This patch updates include/asm-m32r/pgtable.h to add pgprot_noncached(). It is required to fix a problem of an userspace application, which mmaps io registers. This patch also modifies drivers/video/fbmem.c to support noncachable framebuffer access for m32r. In this routine, pgprot_writecombine() is used hopefully, even though the current m32r never does write-combining or write-coalescing... Please apply this. * include/asm-m32r/pgtable.h (pgprot_noncached, pgprot_writecombine): Newly added. * drivers/video/fbmem.c (fb_mmap): Add m32r support. Signed-off-by:

This moves refrigerator changes to sched.h, so that every file user of refrigerator does not have to include suspend.h, and makes refrigerator support easier by introducing try_to_freeze. Adapted from patch by Nigel Cunningham Signed-off-by:

arch/arm/common/sa1111.c: In function `sa1111_suspend': arch/arm/common/sa1111.c:816: warning: assignment from incompatible pointer type This is a rather annoying, and IMHO pointless warning. First question: what is the reasoning for using an array of unsigned bytes here? Are we expecting to power manage devices which only have byte wide registers? In reality, devices have half-word and word sized registers as well, which means that dev->power.saved_state actually points to device specific data (or even device driver specific data) for the device. As such, it makes far more sense for this to be a 'void *'. I'd rather not go around the ARM kernel tree adding pointless casts to 'u8 *' and back again because the wrong type for this was picked in the structure definition, so here's a patch which changes this to void *.
