Save some space on the timing tables by introducing the separate transfer mode
table in which the mode lookup is done to get the index into the timing table
itself. Get rid of the rest of the obsolete/duplicate tables and use one set
of tables for the whole HPT37x chip family like the HighPoint open-source
drivers do. Documnent the different timing register layout for the HPT36x
chip family (this is my guesswork based on the timing values).
Have been tested and works fine on HPT370/302/371N.

Fix/remove bad/unused timing tables: HPT370/A 66 MHz tables weren't really
needed (the chips are not UltraATA/133 capable and shouldn't support 66 MHz
PCI) and had many modes over- and underclocked, HPT372 33 MHz table was in
fact for 66 MHz and 50 MHz table missed UltraDMA mode 6, HPT374 33 MHz table
was really for 50 MHz... (Actually, HPT370/A 33 MHz tables also have issues.
e.g. HPT370 has PIO modes 0/1 overlocked.)
There's also no need in the separate HPT374 tables because HPT372 timings
should be the same (and those tables has UltraDMA mode 6 which HPT374 supports
depending on HPT374_ALLOW_ATA133_6 #define)...

Fix serious problems with the HPT372N clock turnaround code:
- the wrong ports were written to when called for the secondary channel;
- it didn't serialize access to the channels;
- turnaround shou;dn't be done on 66 MHz PCI;
- caching the clock mode per-channel caused it to get out of sync with the
actual register value.
Additionally, avoid calibrating PLL twice (for each channel) as the second try
results in a wrong PCI frequency and thus in the wrong timings.
Make the driver deal with HPT302N and HPT371N correctly -- the clocking and
(seemingly) a need for clock tunaround is the same as for HPT372N. HPT371/N
chips have only one, secondary channel, so avoid touching their "pure virtual"
primary channel, and disable it if the BIOS haven't done this already.
Also, while at it, disable UltraATA/133 for HPT372 by default -- 50 MHz DPLL
clock don't allow for this speed anyway. And remove the traces of the former
bad patch that wasn't even applicable to this version of driver.
Has been tested on HPT370/371N, unfortunately I don't have an instant access
to the other chips...

ib_flush_fmr_pool() stashes away the request generation number
properly, but then goes ahead and rereads it every time it tests
whether the flush generation number has caught up. This means that
there is a theoretical possibility of livelock, if the request
generation number keeps getting bumped and the flush generation number
never catches up. The fix is simple: use the request generation
number read at the beginning of the function.
Also, atomic_inc() followed by atomic_read() can be replaced with
atomic_int_return(). There's no real requirement for atomicity here
but we might as well shrink the code.

This driver adds support for the Apple Motion Sensor (AMS) as found in 2005
revisions of Apple PowerBooks and iBooks. It implements both the PMU and
I2C variants. The I2C driver and mouse emulation is based on code by
Stelian Pop, while the PMU driver has been developped by Michael Hanselmann.
HD parking support will be added later.
Various people contributed fixes to this driver, including
Aristeu Sergio Rozanski Filho and Jean Delvare.

Add support for the Fintek F71872F/FG Super-I/O chip. It is basically the
same as the Fintek F71805F/FG as far as hardware monitoring is concerned,
with two additional internal voltages monitored (VSB and battery), and 6
VID inputs (not yet supported.)
To make things a bit more confusing, two of the voltage input pins (in4
and in8) can be used for other functions. The driver reads the pin
configuration from the Super-I/O configuration space to decide whether
it must create interface files for these inputs or not.
Many thanks to Nikolay Derkach for testing the early iterations of this
code and reporting bugs.

This is a new hardware monitoring driver for the National Semiconductor
PC87427 Super-I/O chip. It only supports fan speed monitoring for now,
while the chip can do much more.
Thanks to Amir Habibi at Candelis for setting up a test system, and to
Michael Kress for testing several iterations of this driver.

This interface was useless as the LPC ISA-like interface is always
available, is faster, and is more reliable. This cuts the driver
size by some 20%.
This change is also required to later convert the it87 driver to a
platform driver, so that we can get rid of i2c-isa in a near future.

In "speed mode", the user specifies a target fan speed (in RPM) and the
chip automatically adjusts the PWM duty cycle (or DC output level) to
reach this target.

pwmN files are writable only in manual fan speed control mode.
In automatic fan speed control modes, they are read-only and

So far we were only extracting the fan skip bit from the
fan control registers, but we'll soon need more bits so
better store the whole register values.

While working on bidi support at struct request level
I have found that blk_queue_activity_fn is actually never used.
The only user is in ide-probe.c with this code:
/* enable led activity for disk drives only */
if (drive->media == ide_disk && hwif->led_act)
blk_queue_activity_fn(q, hwif->led_act, drive);
And led_act is never initialized anywhere.
(Looking back at older kernels it was used in the PPC arch, but was removed around 2.6.18)
Unless it is all for future use off course.

This adds alarm support for the RTC_ALM_SET, RTC_ALM_READ,
RTC_WKALM_SET and RTC_WKALM_RD operations to rtc-sh.
The only unusual part is the handling of the alarm interrupt. If you
clear the alarm flag (AF) while the time in the RTC still matches the
time in the alarm registers than AF is immediately re-set, and if the
alarm interrupt (AIE) is still enabled then it re-triggers. I was
originally getting around 20k+ interrupts generated during the second
when the RTC and alarm registers matches.
The solution I've used is to clear AIE when the alarm goes off and
then use the carry interrupt to re-enabled it. The carry interrupt
will check AF and re-enabled AIE if it's clear. If AF is not clear
it'll clear it and then the check will be repeated next carry
interrupt. This a bit in rtc structure that indicates that it's
waiting to have AIE re-enabled so it doesn't turn it on when it
wasn't enabled anyway.

The RMONCNT register, which holds the month in the RTC, takes a value
between 1 and 12 while the tm_mon field in the time structures takes
a value between 0 and 11. This wasn't being taken into account in
rtc-sh resulting in the month being out by one.
eg, on my board during boot the RTC is set to:
RTC is set to Thu Jul 01 09:00:00 1999
but "hwclock -r" immediately after logging in was showing:
Sun Aug 1 09:01:43 1999 0.000000 seconds
