| | | | | | | | | | | | | | | | | | | | Patch d49c4288 (tip/x86/mpparse) introduced some changes in calling subsys_init calls if CONFIG_X86_NUMAQ option is set.

* x86/pci: removing subsys_initcall ordering dependenciesRobert Richter2008-07-099-21/+36
| | | | | | | | | | | | | | | | | | | | So far subsys_initcalls has been executed in this order depending on the object order in the Makefile: arch/x86/pci/visws.c:subsys_initcall(pcibios_init); arch/x86/pci/numa.c:subsys_initcall(pci_numa_init); arch/x86/pci/acpi.c:subsys_initcall(pci_acpi_init); arch/x86/pci/legacy.c:subsys_initcall(pci_legacy_init); arch/x86/pci/irq.c:subsys_initcall(pcibios_irq_init); arch/x86/pci/common.c:subsys_initcall(pcibios_init); This patch removes the ordering dependency. There is now only one subsys_initcall function that contains subsystem initialization code with a defined order.

There is a code flaw in the bfsort whitelist, where there are redundant entries for the same two HP systems, DL385 G2 and DL585 G2. This patch replaces those redundant entries with the correct ones. The correct entries are for large-volume systems, the DL360 and DL380. ----------------------------------------------------------------------- commit ec69f0374c3b0ad7ea991b0e9ac00377acfe5b1a Author: Tony Camuso <tony.camuso@hp.com> Date: Wed May 14 07:09:28 2008 -0400 Replace Redundant Whitelist Entries with the Correct Ones The ProLiant DL585 G2 and the DL585 G2 are entered reundantly in the dmi_system_id table. What should have been there are the DL360 and DL380.

Amazingly I have a 2.6.23.8 kernel that somehow works fine ... I'll never understand why.

* | | | PCI/x86: fix up PCI stuff so that PCI_GOANY supports OLPCAndres Salomon2008-06-053-4/+6
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, one would have to specifically choose CONFIG_OLPC and CONFIG_PCI_GOOLPC in order to enable PCI_OLPC. That doesn't really work for distro kernels, so this patch allows one to choose CONFIG_OLPC and CONFIG_PCI_GOANY in order to build in OLPC support in a generic kernel (as requested by Robert Millan). This also moves GOOLPC before GOANY in the menuconfig list. Finally, make pci_access_init return early if we detect OLPC hardware. There's no need to continue probing stuff, and pci_pcbios_init specifically trashes our settings (we didn't run into that before because PCI_GOANY wasn't supported).

* / x86/PCI: X86_PAT & mprotectVenki Pallipadi2008-05-131-3/+1
|/ | | | | | | | | | | | | | | | Some versions of X used the mprotect workaround to change caching type from UC to WB, so that it can then use mtrr to program WC for that region [1]. Change the mmap of pci space through /sys or /proc interfaces from UC to UC_MINUS. With this change, X will not need to use mprotect workaround to get WC type since the MTRR mapping type will be honored. The bug in mprotect that clobbers PAT bits is fixed in a follow on patch. So, this X workaround will stop working as well.
