Commit 21855ff5 intel_pstate: Set turbo VID for BayTrail introduced
setting the turbo VID which is required to prevent a machine check on
some Baytrail SKUs under heavy graphics based workloads. The
docmumentation update that brought the requirement to light also
changed the bit mask used for enumerating P state and VID values from
0x7f to 0x3f.
This change returns the mask value to 0x7f.
Tested with the Intel NUC DN2820FYK,
BIOS version FYBYT10H.86A.0034.2014.0513.1413 with v3.16-rc1 and
v3.14.8 kernel versions.

From: Dirk Brandewie <dirk.j.brandewie@intel.com>
If turbo is disabled in the BIOS bit 38 should be set in
MSR_IA32_MISC_ENABLE register per section 14.3.2.1 of the SDM Vol 3
document 325384-050US Feb 2014. If this bit is set do *not* attempt
to disable trubo via the MSR_IA32_PERF_CTL register. On some systems
trying to disable turbo via MSR_IA32_PERF_CTL will cause subsequent
writes to MSR_IA32_PERF_CTL not take affect, in fact reading
MSR_IA32_PERF_CTL will not show the IDA/Turbo DISENGAGE bit(32) as
set. A write of bit 32 to zero returns to normal operation.
Also deal with the case where the processor does not support
turbo and the BIOS does not report the fact in MSR_IA32_MISC_ENABLE
but does report the max and turbo P states as the same value.

ata: Fix the dma state machine lockup for the IDENTIFY DEVICE PIO mode command.
This patch fixes the dma state machine lockup due to the processing
of IDENTIFY DEVICE PIO mode command. The X-Gene AHCI controller
has an errata in which it cannot clear the BSY bit after
receiving the PIO setup FIS and results the dma state machine to go
into the CMFatalErrorUpdate state resulting in the dma state
machine lockup. This patch also removes the dma restart workaround
from the read_id function as the read_id function is only called by
libata layer for ATA_INTERNAL commands. But for somecases eg:
PORT MULTIPLIER and udev, the framework will enumerate using SCSI
commands and it will not call read_id function.
