2007-07-11PCI: hotplug: acpiphp: remove hot plug parameter write to PCI host bridgeGary Hade
acpiphp is writing hot plug parameters to the PCI host bridge PCI config space. This patch removes the incorrect operation.

2007-07-11PCI: hotplug: acpiphp: fix slot poweroff problem on systems without _PS3Gary Hade
On systems where the optional _PS3 ACPI object is not implemented acpiphp fails to power off the slot. This is happening because the current code does not attempt to remove power using the _EJ0 ACPI object. This patch restores the _EJ0 evaluation attempt which was apparently inadvertently removed from the power-off sequence when the _EJ0 evaluation code was relocated from power_off_slot() to acpiphp_eject_slot().

2007-07-11PCI: Change all drivers to use pci_device->revisionAuke Kok
Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance. Compile tested with make all{yes,mod}config on x86_64 and i386.

The Via VT3351 APIC does not play well with MSI and unleashes a flood of APIC errors when MSI is used to deliver interrupts. The problem was recently exposed when the atl1 network device driver, which enables MSI by default, stimulated APIC errors on an Asus M2V mainboard, which employs the Via VT3351.

2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).

2007-05-11Fix assertion failure with MSI on sparc64David Miller
Today's find is a triggered assertion in msi_free_irqs() when the system doesn't support MSI, in which case arch_setup_msi_irqs() always returns an error. The problem is that when this happens we branch into msi_free_irqs(), to which you added the following assertion loop: list_for_each_entry(entry, &dev->msi_list, list) BUG_ON(irq_has_action(entry->irq)); Well, if arch_setup_msi_irqs() fails, entry->irq will be zero and although that's never assigned to any normal devices we use that IRQ number for the timer interrupt on sparc64 so this assertion triggers. Better to test for zero before doing the irq_has_action() assertion thing. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-05-02PCI: rpaphp: Remove semaphoresLinas Vepstas
Remove the semaphores from the get routine. These do not appear to be protecting anything that I can make out, and they also do not seem to be required by the hotplug driver.

2007-05-02PCI: rpaphp: Ensure more pcibios_add/pcibios_remove symmetryLinas Vepstas
Calls to pcibios_add should be symmetric with calls to pcibios_remove. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Cc: John Rose <johnrose@austin.ibm.com> Signed-off-by: Kristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-05-02PCI: rpaphp: Use pcibios_remove_pci_devices() symmetricallyLinas Vepstas
At first blush, the disable_slot() routine does not look at all like its symmetric with the enable_slot() routine; as it seems to call a very different set of routines. However, this is easily fixed: pcibios_remove_pci_devices() does the right thing.

2007-05-02PCI: rpaphp: Document is_php_dn()Linas Vepstas
Fix up the documentation: the rpaphp_add_slot() does not actually handle embedded slots: in fact, it ignores them. Fix the flow of control in the routine that checks for embedded slots.

2007-05-02PCI: rpaphp: Document find_php_slot()Linas Vepstas
Document some of the interaction between dlpar and hotplug. viz, the a dlpar remove of a htoplug slot uses hotplug to remove it.

2007-05-02PCI: rpaphp: Rename rpaphp_register_pci_slot() to rpaphp_enable_slot()Linas Vepstas
Rename rpaphp_register_pci_slot() because its easy to confuse with rpaphp_register_slot() even though it does something completely different. Rename it to rpaphp_enable_slot() because its almost identical to enbale_slot().

2007-05-02PCI: rpaphp: refactor tail call to rpaphp_register_slot()Linas Vepstas
Eliminate the tail call to rpaphp_register_slot() by placing it in the caller. This will help later dis-entanglement.

2007-05-02PCI: rpaphp: remove rpaphp_set_attention_status()Linas Vepstas
The rpaphp_set_attention_status() routine seems to be a wrapper around a single rtas call. Abolish it.
