This is a rewrite of Andi Kleen's bloat-o-meter with sorting and reporting of gainers/decliners. Sample output: add/remove: 0/8 grow/shrink: 2/0 up/down: 88/-4424 (-4336) function old new delta __copy_to_user_ll 59 103 +44 __copy_from_user_ll 59 103 +44 fill_note 32 - -32 maydump 58 - -58 dump_seek 67 - -67 writenote 180 - -180 elf_dump_thread_status 274 - -274 fill_psinfo 308 - -308 fill_prstatus 466 - -466 elf_core_dump 3039 - -3039 The summary line says: no functions added, 8 removed two functions grew, none shrunk we gained 88 bytes and lost 4424 (or -4336 net) This work was sponsored in part by CE Linux Forum Signed-off-by:

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 bce61dd4 ("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). Signed-off-by:

Jan Blunck authored
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." Signed-off-by: -

Earlier fix removed unused phase, but that changed the values for other phases. Since these are exposed to userspace through ppdev, it is safer not to change them. Restore the unused phase value. Signed-off-by:

- remove unnecessary -ENOMEM assignments - return correct value when buf_check_size for second time in a buffer - handle failures when create_workqueue and kthread_create are called - use kzalloc instead of kmalloc/memset 0 - v9fs_str_copy and v9fs_str_compare were buggy, were used only in one place, correct the logic and move it to the place it is used.

v9fs_create doesn't manage correctly the fids when it is called to create a directory.. The fid created by the create 9P call (newfid) and the one created by walking to already created file (wfidno) are not used consistently. This patch cleans up the usage of newfid and wfidno. Signed-off-by:

Eric Van Hensbergen authored
If a 9pfs server crashes, v9fs_fd_close() is called. Subsequently, in cleaning up by performing a umount() on the FS that was provided by this server v9fs_fd_close() is called again, and uses the old, freed valus of trans->priv. This patch ensures that trans->priv can be freed only once, otherwise this function bails early. Signed-off-by:

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.

Bjorn Helgaas authored
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.
