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:

include/asm-m32r/elf.h: Add relocations R_M32R_GOTOFF_HI_ULO, R_M32R_GOTOFF_HI_SLO, and R_M32R_GOTOFF_LO. These relocations are required to implement GOTOFF support for m32r. 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:

Some machines are spending minutes of CPU time during suspend in stupid O(n^2) algorithm. This patch replaces it with O(n) algorithm, making swsusp usable to some people. Signed-off-by:

This adds statics at few places and fixes stale references to pmdisk. Signed-off-by:

swsusp contains few one-line helpers that only make reading/understanding code more difficult. Also warn the user when something goes wrong, instead of waking machine with corrupt data. Signed-off-by:

At few points we still reference to swsusp as "pmdisk"... it might confuse someone not knowing full history. 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 *.

This removes some unneeded definitions and makes the naming used within the file more consistent. Also adds some macros to make it easier to see how the interrupt handler is structured. The assembled output is identical to the original. Signed-off-by:

- Updates to makefiles required by the other changes in this patchset. - Also add some entries to the linker scripts.

Add SLIT (inter node distance) information to sysfs. [This is Jack's patch that he submitted on l-k. I'm submitting it for him because I need it for my x86-64 followon SLIT patch. Hope I don't stomp onto his toes with that one. If you already merged it please ignore] From: Jack Steiner Here is an update patch to externalize the SLIT information. I think I have encorporated all the comments that were posted previously) For example: # cd /sys/devices/system # find . ./node ./node/node5 ./node/node5/distance ./node/node5/numastat ./node/node5/meminfo ./node/node5/cpumap # cat ./node/node0/distance 10 20 64 42 42 22 # cat node/*/distance 10 20 64 42 42 22 20 10 42 22 64 84 64 42 10 20 22 42 42 22 20 10 42 62 42 64 22 42 10 20 22 84 42 62 20 10 Signed-off-by:Jack Steiner <steiner@sgi.com> Signed-off-by:
