2009-03-27ACPICA: New: I/O port protectionBob Moore

2009-03-27ACPICA: Fix AcpiWalkNamespace race condition with table unloadBob Moore
Added a reader/writer locking mechanism to allow multiple concurrent namespace walks (readers), but a dynamic table unload will have exclusive access to the namespace. This fixes a problem where a table unload could delete the portion of the namespace that is currently being examined by a walk. Adds a new file, utlock.c that implements the reader/writer lock mechanism.

2009-03-26ACPICA: Split out PM1 status registers from the FADTBob Moore
Add new globals for the PM1 status registers (A/B), similar to the way the PM1 enable registers are handled. Instead of overloading the FADT Event Register blocks. This makes the code clearer and less prone to error. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-03-26ACPICA: Allow OS override of all ACPI tablesBob Moore
Previously, the table override mechanism was implemented for the DSDT only. Now, any table in the RSDT/XSDT can be replaced by the host OS. (including the DSDT).
