"[CPUFREQ] cpumask: avoid playing with cpus_allowed in speedstep-ich.c"
changed the code to mistakenly pass the current cpu as the "processor"
argument of speedstep_get_frequency(), whereas it should be the type of
the processor.
Addresses http://bugzilla.kernel.org/show_bug.cgi?id=14340

notification message
Removing the SMT/HT check, since the Errata doesn't mention
Hyper-Threading.
Adding in a printk, so that the user knows why acpi-cpufreq refuses to
load. Also, once system is blacklisted, don't repeat checks to see if
blacklisted. This also causes the message to only be printed once,
rather than for each CPU.

There is a typo in the longhaul detection code so only Longhaul v1 or Longhaul v3
is selected. The Longhaul v2 is not selected even for CPUs which are capable of.
Tested on PCChips Giga Pro board. Frequency changes work and the Longhaul v2
detects that the board is not capable of changing CPU voltage.

Fix the freqsel value computation. Use n instead of (n+1)
The formula in the TRM uses a zero-based N, hence the (n+1); however

The current MTRR code treats WP as a form of UC. This really isn't

These values were only introduced during this release cycle, so it is

remove them.
parisc uses the values interchanged for no apparent reason, so remove

Since commit 0a544198 "timekeeping: Move NTP adjusted clock multiplier
to struct timekeeper" the clock multiplier of vsyscall is updated with
the unmodified clock multiplier of the clock source and not with the
NTP adjusted multiplier of the timekeeper.
This causes user space observerable time warps:
new CLOCK-warp maximum: 120 nsecs, 00000025c337c537 -> 00000025c337c4bf
Add a new argument "mult" to update_vsyscall() and hand in the
timekeeping internal NTP adjusted multiplier.

This kills bad_dma_address variable, the old mechanism to enable
IOMMU drivers to make dma_mapping_error() work in IOMMU's
specific way.
bad_dma_address variable was introduced to enable IOMMU drivers
to make dma_mapping_error() work in IOMMU's specific way.
However, it can't handle systems that use both swiotlb and HW
IOMMU. SO we introduced dma_map_ops->mapping_error to solve that
case.
Intel VT-d, GART, and swiotlb already use
dma_map_ops->mapping_error. Calgary, AMD IOMMU, and nommu use
zero for an error dma address. This adds DMA_ERROR_CODE and
converts them to use it (as SPARC and POWER does).

GART IOMMU is the only user of bad_dma_address variable.

->mapping_error() in struct dma_map_ops, to make
dma_mapping_error() work in IOMMU specific way.

It is possible for x86_64 systems to lack the NX bit either due to the
hardware lacking support or the BIOS having turned off the CPU capability,
so NX status should be reported. Additionally, anyone booting NX-capable
CPUs in 32bit mode without PAE will lack NX functionality, so this change
provides feedback for that case as well.

The 32- and 64-bit code used very different mechanisms for enabling
NX, but even the 32-bit code was enabling NX in head_32.S if it is
available. Furthermore, we had a bewildering collection of tests for
the available of NX.
This patch:
a) merges the 32-bit set_nx() and the 64-bit check_efer() function
into a single x86_configure_nx() function. EFER control is left
to the head code.
b) eliminates the nx_enabled variable entirely. Things that need to
test for NX enablement can verify __supported_pte_mask directly,
and cpu_has_nx gives the supported status of NX.

This will fix some small issues with the COH 901 331 RTC driver:
- Interrupt is disabled after alarm so that we don't fire
multiple interrupts.
- We return 0 from the coh901331_alarm_irq_enable() ridding
a compile warning.
- We alter the name in the U300 device registry to match that
of the driver so they sucessfully resolve.
