Subject: [PATCH 0/2] ACPI: Early _PDC tweaks
Date: Wed, 20 Jan 2010 00:06:25 -0700 [thread overview]
Message-ID: <20100120070403.19777.31978.stgit@bob.kio> (raw)
As requested by Len, a few more improvements in how we handle the
early _PDC path.
Allow platforms not listed in the DMI table to opt-in for early _PDC
with a kernel command line param.
If we do evaluate _PDC early, remember that fact and do not evaluate
it a second time when the ACPI processor driver loads.

ACPI: processor: add kernel command line support for early _PDC eval
ACPI: processor: only evaluate _PDC once per processor
