IB/ipath: Shadow the gpio_mask register

Once upon a time, GPIO interrupts were rare.  But then a chip bug in
the waldo series forced the use of a GPIO interrupt to signal packet
reception.  This greatly increased the frequency of GPIO interrupts
which have the gpio_mask bits set on the waldo chips.  Other bits in
the gpio_status register are used for I2C clock and data lines, these
bits are usually on.  An "unlikely" annotation leftover from the old
days was improperly applied to these bits, and an unnecessary chip
mmio read was being accessed in the interrupt fast path on waldo.

Remove the stagnant unlikely annotation in the interrupt handler and
keep a shadow copy of the gpio_mask register to avoid the slow mmio
read when testing for interruptable GPIO bits.

Daniel Drake [Wed, 2 May 2007 22:19:05 +0000 (23:19 +0100)]
[CPUFREQ] powernow-k7: fix MHz rounding issue with perflib

When the PST tables are broken, powernow-k7 uses ACPI's processor_perflib to
deduce the available frequency multipliers from the _PSS tables.

Upon frequency change, processor_perflib performs some verification on the
frequency (checks that it's within allowable bounds).

powernow-k7 deals with absolute frequencies in KHz, whereas perflib only
deals with MHz values. When performing the above verification, perflib
multiplies the MHz values by 1000 to obtain the KHz value.

We then end up with situations like the following:
 - powernow-k7 multiplies the multiplier by the FSB, and obtains a value
   such as 1266768 KHz
 - perflib belives the same state has frequency of 1266 MHz
 - acpi_processor_ppc_notifier calls cpufreq_verify_within_limits to verify
   that 1266768 is in the allowable range of 0 to 1266000 (i.e. 1266 * 1000)
 - it's not, so that frequency is rejected
 - the maximum CPU frequency is not reachable

This patch solves the problem by rounding up the MHz values stored in perflib's
tables. Additionally it corrects a broken URL.

It also fixes http://bugzilla.kernel.org/show_bug.cgi?id=8255 although this
case is a bit different: the frequencies in the _PSS tables are wildly wrong,
but we get better results if we force ACPI to respect the fsb * multiplier
calculations (even though it seems that the multiplier values aren't entirely
correct either).

The Motorola PrPMC280 and PrPMC2800 processor modules sit on an F101 or
PrPMC2800 baseboard, respectively.  There are several variants of each
type of processor module which can have different amounts of memory,
amounts of FLASH, cpu frequencies, and an mv64360 or an mv64362.

to determine the processor module variant.  From the variant, the
amount of memory, etc. is determined and the device tree is updated
accordingly.  If the variant cannot be determined (e.g., corrupted
VPD or a previously unknown variant), the property values already
in the device tree are used.

Also, the firmware for those platforms does not completely configure
