* [PATCH] acpi_shutdown: Only prepare for power off on power_offEric W. Biederman2005-08-27
| | | | | | | | | | | | | When acpi_sleep_prepare was moved into a shutdown method we started calling it for all shutdowns. It appears this triggers some systems to power off on reboot. Avoid this by only calling acpi_sleep_prepare if we are going to power off the system. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* | Revert ACPI interrupt resume changesLinus Torvalds2005-08-01
| | | | | | | | | | | | | | | | | | If there are devices that use interrupts over a suspend event, ACPI must restore the PCI interrupt links on resume. Anything else breaks any device that hasn't been converted to the new (dubious) PM rules. Drivers that need the irq free/re-aquire sequence can be done one by one independently of this one.

* | [PATCH] acpi: Don't call acpi_sleep_prepare from acpi_power_offEric W. Biederman2005-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that all of the code paths that call acpi_power_off have been modified to call either call kernel_power_off (which calls apci_sleep_prepare by way of acpi_shutdown) or to call acpi_sleep_prepare directly it is redundant to call acpi_sleep_prepare from acpi_power_off. So simplify the code and simply don't call acpi_sleep_prepare. In addition there is a little error handling done so if we can't register the acpi class we don't hook pm_power_off. I think I have done the right thing with the CONFIG_PM define but I'm not certain. Can this code even be compiled if CONFIG_PM is false? Signed-off-by: Eric W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | machine_power_off on i386 and x86_64 now switch to the boot cpu out of paranoia and because the MP Specification indicates it is a good idea on reboot, so for those architectures it is a noop. I can't see anything in the acpi spec that requires you to be on the boot cpu to power off the system, so this should not be an issue for ia64. In addition ia64 has the altix a massive multi-node system where switching to the boot cpu sounds insane as we may hot removed the boot cpu. Signed-off-by: Eric W.

This was the Index argument to the Index, Mid, and Match operators. The "strupr" function is now permanently local (acpi_ut_strupr), since this is not a POSIX-defined function and not present in most kernel-level C libraries. References to the C library strupr function have been removed from the headers. Completed the deployment of static functions/prototypes. All prototypes with the static attribute have been moved from the headers to the owning C file. ACPICA 20050329 from Bob Moore An error is now generated if an attempt is made to create a Buffer Field of length zero (A CreateField with a length operand of zero.) The interpreter now issues a warning whenever executable code at the module level is detected during ACPI table load. This will give some idea of the prevalence of this type of code. Implemented support for references to named objects (other than control methods) within package objects. Enhanced package object output for the debug object. Package objects are now completely dumped, showing all elements. Enhanced miscellaneous object output for the debug object. Any object can now be written to the debug object (for example, a device object can be written, and the type of the object will be displayed.) The "static" qualifier has been added to all local functions across the core subsystem. The number of "long" lines (> 80 chars) within the source has been significantly reduced, by about 1/3. Cleaned up all header files to ensure that all CA/iASL functions are prototyped (even static functions) and the formatting is consistent. Two new header files have been added, acopcode.h and acnames.h. Removed several obsolete functions that were no longer used. Signed-off-by: Len Brown <len.brown@intel.com>
