2009-01-07ACPI/PCI: PCI extended config _OSC support called when root bridge addedAndrew Patterson4-2/+31
The _OSC capability OSC_EXT_PCI_CONFIG_SUPPORT is set when the root bridge is added with pci_acpi_osc_support() if we can access PCI extended config space. This adds the function pci_ext_cfg_avail which returns true if we can access PCI extended config space (offset greater than 0xff). It currently only returns false if arch=x86 and raw_pci_ext_ops is not set (which might happen if pci=nommcfg is set on the kernel command-line).

2009-01-07ACPI/PCI: call _OSC support during root bridge discoveryAndrew Patterson3-5/+29
Add pci_acpi_osc_support() and call it when a PCI bridge is added. This allows us to avoid having every individual PCI root bridge driver call _OSC support for every root bridge in their probe functions, a significant savings in boot time.

2009-01-07PCI: Add legacy_io/mem to all bussesBenjamin Herrenschmidt1-0/+4
Currently, only PHBs get the legacy_* files, which makes it tricky for userland to get access to the legacy space. This commit exposes them in every bus, since even child buses may forward legacy cycles if configured properly.

2009-01-07PCI: struct device - replace bus_id with dev_name(), dev_set_name()Kay Sievers6-8/+8
This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id.

2009-01-07PCI hotplug: pciehp: remove unnecessary wait after turning power offKenji Kaneshige1-14/+12
The pciehp driver waits for 1000 msec after turning power off to make sure the power has been completely removed. But this 1000 msec wait is not needed if a slot doesn't implement power control because software cannot control the power. Power will be automatically removed at adapter removal time on such a slot Tested-by: "Phil Endecott" <phil_pibbu_endecott@chezphil.org> Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2009-01-07Fix up 64-bit byte swaps for most 32-bit architecturesLinus Torvalds1-1/+1
The __SWAB_64_THRU_32__ case of a 64-bit byte swap was depending on the no-longer-existant ___swab32() method (three underscores). We got rid of some of the worst indirection and complexity, and now it should just use the 32-bit swab function that was defined right above it.

2009-01-07byteorder: only use linux/swab.hHarvey Harrison6-388/+27
The first step to make swab.h a regular header that will include an asm/swab.h with arch overrides. Avoid the gratuitous differences introduced in the new linux/swab.h by naming the ___constant_swabXX bits and __fswabXX bits exactly as found in the old implementation in byteorder/swab[b].h Use this new swab.h in byteorder/[big|little]_endian.h and remove the two old swab headers. Although the inclusion of asm/byteorder.h looks strange in linux/swab.h, this will allow each arch to move the actual arch overrides for the swab bits in an asm file and then the includes can be cleaned up without requiring a flag day for all arches at once. Keep providing __fswabXX in case some userspace was using them directly, but the revised __swabXX should be used instead in any new code and will always do constant folding not dependent on the optimization level, which means the __constant versions can be phased out in-kernel. Arches that use the old-style arch macros will lose their optimized versions until they move to the new style, but at least they will still compile. Many arches have already moved and the patches to move the remaining arches are trivial.

This avoids a BUG_ON in the enter_vt path due to objects being in the GTT when we shouldn't have ever let them be (as we're not supposed to touch the device during that time). This was triggered by a change in the 2D driver to use the GTT mapping of objects after pinning them to improve software fallback performance.

2009-01-07parport: ieee1284: use del_timer_sync() in parport_wait_event()Michael Buesch1-1/+1
Use del_timer_sync() instead of del_timer() to make sure the timer won't be running when we return from parport_wait_event(), because this would crash due to destruction of timer_list. This is untested and just based on a code review. Just think about the following sequence of events: - add_timer() - down_interruptible() is interrupted by a signal. - we enter the timer callback handler on another CPU. - del_timer(), but the timer callback is still running. - eturn from parport_wait_even, which destroys the automatic variable "timer" while the callback is running on another CPU.
