driver core: warn about duplicate driver names on the same bus

2008-04-30T23:52:47+00:00

Currently an attempt to register multiple
drivers with the same name causes the
stack trace with some cryptic error message.
The attached patch adds the necessary check
and the clear error message.

mm: Add NR_WRITEBACK_TEMP counter

2008-04-30T15:29:50+00:00

Fuse will use temporary buffers to write back dirty data from memory mappings
(normal writes are done synchronously).  This is needed, because there cannot
be any guarantee about the time in which a write will complete.

By using temporary buffers, from the MM's point if view the page is written
back immediately.  If the writeout was due to memory pressure, this
effectively migrates data from a full zone to a less full zone.

This patch adds a new counter (NR_WRITEBACK_TEMP) for the number of pages used
as temporary buffers.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86-bigbox-pci

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86-bigbox-pci:
  x86: add pci=check_enable_amd_mmconf and dmi check
  x86: work around io allocation overlap of HT links
  acpi: get boot_cpu_id as early for k8_scan_nodes
  x86_64: don't need set default res if only have one root bus
  x86: double check the multi root bus with fam10h mmconf
  x86: multi pci root bus with different io resource range, on 64-bit
  x86: use bus conf in NB conf fun1 to get bus range on, on 64-bit
  x86: get mp_bus_to_node early
  x86 pci: remove checking type for mmconfig probe
  x86: remove unneeded check in mmconf reject
  driver core: try parent numa_node at first before using default
  x86: seperate mmconf for fam10h out from setup_64.c
  x86: if acpi=off, force setting the mmconf for fam10h
  x86_64: check MSR to get MMCONFIG for AMD Family 10h
  x86_64: check and enable MMCONFIG for AMD Family 10h
  x86_64: set cfg_size for AMD Family 10h in case MMCONFIG
  x86: mmconf enable mcfg early
  x86: clear pci_mmcfg_virt when mmcfg get rejected
  x86: validate against acpi motherboard resources

Fixed up fairly trivial conflicts in arch/x86/pci/{init.c,pci.h} due to
OLPC support manually.

firmware loader: printk when requesting firmware

2008-04-29T15:06:05+00:00

Before requesting firmware, printk a message saying what we're requesting. This
makes it easier to see what's going on, and provides an explanation for the
huge silent delay that one would otherwise get after accidentally building
ipw2200 as a non-module.

driver core: try parent numa_node at first before using default

2008-04-26T21:41:04+00:00

in the device_add, we try to use use parent numa_node.
need to make sure pci root bus's bridge device numa_node is set.
then we could use device->numa_node direclty for all device.
and don't need to call pcibus_to_node().

bus_remove_device: be more careful about incomplete initialization

2008-04-23T00:40:36+00:00

Prevent bus_remove_device() from crashing if dev->knode_bus has not been
initialized before it's called.

This can happen if the device_add() ended up breaking out early due to
an error, for example.
