* lib: percpu_counter_subPeter Zijlstra2007-10-174-3/+8
| | | | | | | | | | | | | | | | | | | Hugh spotted that some code does: percpu_counter_add(&counter, -unsignedlong) which, when the amount argument is of type s32, sort-of works thanks to two's-complement. However when we'd change the type to s64 this breaks on 32bit machines, because the promotion rules zero extend the unsigned number. Provide percpu_counter_sub() to hide the s64 cast. That is: percpu_counter_sub(&counter, foo) is equal to: percpu_counter_add(&counter, -(s64)foo); Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Hugh Dickins <hugh@veritas.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* nfs: remove congestion_end()Peter Zijlstra2007-10-173-17/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These patches aim to improve balance_dirty_pages() and directly address three issues: 1) inter device starvation 2) stacked device deadlocks 3) inter process starvation 1 and 2 are a direct result from removing the global dirty limit and using per device dirty limits. By giving each device its own dirty limit is will no longer starve another device, and the cyclic dependancy on the dirty limit is broken. In order to efficiently distribute the dirty limit across the independant devices a floating proportion is used, this will allocate a share of the total limit proportional to the device's recent activity. 3 is done by also scaling the dirty limit proportional to the current task's recent dirty rate. This patch: nfs: remove congestion_end(). It's redundant, clear_bdi_congested() already wakes the waiters.

* powerpc: add Altivec/VMX state to coredumpsMark Nelson2007-10-173-3/+34
| | | | | | | | | | | | | | | | | | | | Update dump_task_altivec() (which has so far never been put to use) so that it dumps the Altivec/VMX registers (VR[0] - VR[31], VSCR and VRSAVE) in the same format as the ptrace get_vrregs(), and add the appropriate glue typedef and #defines to make it work. A new note type of NT_PPC_VMX was chosen to be 0x100 (arbitrarily) because it allows the low range values to be used for more generic purposes and 0x100 seems an adequate starting point for PowerPC extensions.

* x86: replace NT_PRXFPREG with ELF_CORE_XFPREG_TYPE #defineMark Nelson2007-10-175-8/+11
| | | | | | | | | | | | | | | | | | | | | | | | Replace NT_PRXFPREG with ELF_CORE_XFPREG_TYPE in the coredump code which allows for more flexibility in the note type for the state of 'extended floating point' implementations in coredumps. New note types can now be added with an appropriate #define. This does #define ELF_CORE_XFPREG_TYPE to be NT_PRXFPREG in all current users so there's are no change in behaviour. This will let us use different note types on powerpc for the Altivec/VMX state that some PowerPC cpus have (G4, PPC970, POWER6) and for the SPE (signal processing extension) state that some embedded PowerPC cpus from Freescale have.

* partially fix up the lookup_one_noperm messChristoph Hellwig2007-10-173-26/+39
| | | | | | | | | | | | | | | | | | | | | | | Try to fix the mess created by sysfs braindamage. - refactor code internal to fs/namei.c a little to avoid too much duplication: o __lookup_hash_kern is renamed back to __lookup_hash o the old __lookup_hash goes away, permission checks moves to the two callers o useless inline qualifiers on above functions go away - lookup_one_len_kern loses it's last argument and is renamed to lookup_one_noperm to make it's useage a little more clear - added kerneldoc comments to describe lookup_one_len aswell as lookup_one_noperm and make it very clear that no one should use the latter ever.

This gives use a standardized output similar to the rest of the kernel, and eliminates the need to manually print out PCI bus id. * use DRV_NAME constant where appropriate * clean struct pci_driver indentation Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| | | | | | | | | | | | | | | | | | It has been obsoleted since 1 Nov 2004, is valid only when used together with "ide=nodma" kernel parameter (which makes no sense) and only for aec62xx, cmd64x, cs5220, generic, hpt366, sl82c105, tc86c001 and triflex host drivers.

| * ide: remove CONFIG_BLK_DEV_IDEDMA_FORCEDBartlomiej Zolnierkiewicz2007-10-162-51/+3
| | | | | | | | | | | | | | | | | | This code doesn't use pci_assign_resource() and ide_get_or_set_dma_base() uses pci_resource_start() to get DMA base address so it has no chance of working. Moreover this belongs to PCI quirks (in case somebody would like to fix it). Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
