-
-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.

-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.
