2007-05-09Revert "ACPICA: fix AML mutex re-entrancy"Len Brown
This reverts commit c0d127b56937c3e72c2b1819161d2f6718eee877. These changes to AML locking were made to allow Notify handlers to be called on the stack and not deadlock. However, that scheme turns out to be flawed and was reverted by the previous commit, so this commit restores the locking to it previous design. Signed-off-by: Len Brown <len.brown@intel.com>
2007-05-09Revert "ACPICA: revert "acpi_serialize" changes"Len Brown
This reverts commit a8f4af6dc6600980885c594f52eecd60edd62013. Thus restoring ACPICA's new acpi_serialize code. This commit by itself may cause a regression, but it is reverted in this order so that subsequent reverts reverts under this one can be made without conflict.

2007-05-08PNPACPI sets pnpdev->dev.archdataDavid Brownell
Teach PNPACPI how to hook up its devices to their ACPI nodes, so that pnpdev->dev.archdata points to the parallel acpi device node. Previously this only worked for PCI, leaving a notable hole. Export "acpi_bus_type" so this can work. Remove some extraneous whitespace.

2007-05-02remove "struct subsystem" as it is no longer neededGreg Kroah-Hartman
We need to work on cleaning up the relationship between kobjects, ksets and ktypes. The removal of 'struct subsystem' is the first step of this, especially as it is not really needed at all. Thanks to Kay for fixing the bugs in this patch. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2007-03-19ACPI: IA64: fix %ll build warningsLen Brown
acpi_integer is 64-bits on all platforms, and so was defined as a u64. i386 and x86_64 define u64 as unsigned long long. ia64 defines u64 as long. While these are all 64-bits, the kernel build warns about formating a "long" with %ll: drivers/ata/libata-acpi.c:176: warning: long long unsigned int format, acpi_integer arg (arg 5) So skip using "u64" and define acpi_integer as "unsigned long long" to make gcc happy with %ll.

2007-02-16[PATCH] ACPI keep track of timer broadcastingThomas Gleixner
This is a preperatory patch for highres/dyntick: - replace the big #ifdef ARCH_APICTIMER_STOPS_ON_C3 hackery by functions - remove the double switch in the power verify function (in the worst case we switched ipi to apic and 20usec later apic to ipi) - keep track of the the state which stops local APIC timer Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Cc: Len Brown <len.brown@intel.com> Cc: <linux-acpi@vger.kernel.org> Cc: Andi Kleen <ak@suse.de> Cc: john stultz <johnstul@us.ibm.com> Cc: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-02-15ACPICA: fix AML mutex re-entrancyAlexey Starikovskiy
ACPI AML supports "serialized" methods which are protected by an implicit mutex. The mutex is re-entrant for that AML thread to allow recursion. However, Linux implements notify() by creating a new AML thread. So for systems where notify() re-enters a serialized method, deadlock results. The fix is to use the Linux thread_id as the key to allowing re-entrancy, not the AML thread pointer. http://bugzilla.kernel.org/show_bug.cgi?id=5534 Signed-off-by: Alexey Starikovskiy <alexey.y.starikovskiy@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
