* [PATCH] fix workqueue oops during cpu offlineNathan Lynch2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | Use first_cpu(cpu_possible_map) for the single-thread workqueue case. We used to hardcode 0, but that broke on systems where !cpu_possible(0) when workqueue_struct->cpu_workqueue_struct was changed from a static array to alloc_percpu. Commit id bce61dd49d6ba7799be2de17c772e4c701558f14 ("Fix hardcoded cpu=0 in workqueue for per_cpu_ptr() calls") fixed that for Ben's funky sparc64 system, but it regressed my Power5. Offlining cpu 0 oopses upon the next call to queue_work for a single-thread workqueue, because now we try to manipulate per_cpu_ptr(wq->cpu_wq, 1), which is uninitialized. So we need to establish an unchanging "slot" for single-thread workqueues which will have a valid percpu allocation. Since alloc_percpu keys off of cpu_possible_map, which must not change after initialization, make this slot == first_cpu(cpu_possible_map).

| | | | | | | | | | | | | | | | | | | | | | | | | Since version 4.1 the gcc is warning about ignored attributes. This patch is using the equivalent attribute on the struct instead of on each of the structure or union members. GCC Manual: "Specifying Attributes of Types packed This attribute, attached to struct or union type definition, specifies that each member of the structure or union is placed to minimize the memory required. When attached to an enum definition, it indicates that the smallest integral type should be used. Specifying this attribute for struct and union types is equivalent to specifying the packed attribute on each of the structure or union members."

| | | | | | | | | | | | | | | | | Reorder members of the kiocb structure to make sync kiocb setup faster. By setting the elements sequentially, the write combining buffers on the CPU are able to combine the writes into a single burst, which results in fewer cache cycles being consumed, freeing them up for other code. This results in a 10-20KB/s[*] increase on the bw_unix part of LMbench on my test system. * The improvement varies based on what other patches are in the system, as there are a number of bottlenecks, so this number is not absolutely accurate.

* [PATCH] /dev/mem: validate mmap requestsBjorn Helgaas2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a hook so architectures can validate /dev/mem mmap requests. This is analogous to validation we already perform in the read/write paths. The identity mapping scheme used on ia64 requires that each 16MB or 64MB granule be accessed with exactly one attribute (write-back or uncacheable). This avoids "attribute aliasing", which can cause a machine check. Sample problem scenario: - Machine supports VGA, so it has uncacheable (UC) MMIO at 640K-768K - efi_memmap_init() discards any write-back (WB) memory in the first granule - Application (e.g., "hwinfo") mmaps /dev/mem, offset 0 - hwinfo receives UC mapping (the default, since memmap says "no WB here") - Machine check abort (on chipsets that don't support UC access to WB memory, e.g., sx1000) In the scenario above, the only choices are - Use WB for hwinfo mmap. Can't do this because it causes attribute aliasing with the UC mapping for the VGA MMIO space. - Use UC for hwinfo mmap. Can't do this because the chipset may not support UC for that region. - Disallow the hwinfo mmap with -EINVAL. That's what this patch does.

* [PATCH] Abandon gcc-2.95.xAndrew Morton2006-01-08
| | | | | | | | | | | | | | There's one scsi driver which doesn't compile due to weird __VA_ARGS__ tricks and the rather useful scsi/sd.c is currently getting an ICE. None of the new SAS code compiles, due to extensive use of anonymous unions. The V4L guys are very good at exploiting the gcc-2.95.x macro expansion bug (_why_ does each driver need to implement its own debug macros?) and various people keep on sneaking in anonymous unions, which are rather nice. Plus anonymous unions are rather useful. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] block/stat.txtAndy Isaacson2006-01-08
| | | | | | | | | | | | | | I couldn't find any docs explaining the contents of /sys/block/<dev>/stat, so I wrote up the following. I'm not completely sure it's accurate - Jens, could you give a yea or nay on this? In particular, the counts of read/write IOs and read/write sectors are incremented in different places - it looks like they both increment as the request is being finished, but I'm not completely sure of that.

* [PATCH] setpgid: should not accept ptraced childsOleg Nesterov2006-01-08
| | | | | | | | | | | | | sys_setpgid() allows to change ->pgrp of ptraced childs. 'man setpgid' does not tell anything about that, so I consider this behaviour is a bug.
