Rusty Russell 9ef7ad2296 Enable partitions for lguest block device
The lguest block device only requests one minor, which means
partitions don't work (eg "root=/dev/lgba1").

Let's follow the crowd and ask for 16.

Kumar Gala b66510cb99 [POWERPC] Fix interrupt routing and setup of ULI M1575 on FSL boards
The interrupt routing in the device trees for the ULI M1575 was
inproperly using the interrupt line field as pci function.  Fixed
up the device tree's to actual conform for to specification and
changed the interrupt mapping code so it just uses a static mapping
setup as follows:

PIRQA - IRQ9
PIRQB - IRQ10
PIRQC - IRQ11
PIRQD - IRQ12
USB 1.1 OCHI (1c.0) - IRQ12
USB 1.1 OCHI (1c.1) - IRQ9
USB 1.1 OCHI (1c.2) - IRQ10
USB 1.1 ECHI (1c.3) - IRQ11
LAN (1b.0) - IRQ6
AC97 (1d.0) - IRQ6
Modem (1d.1) - IRQ6
HD Audio (1d.2) - IRQ6
SATA (1f.1) - IRQ5
SMB (1e.1) - IRQ7
PMU (1e.2) - IRQ7
PATA (1f.0) - IRQ14/15

Took the oppurtunity to refactor the code into a single file so we
don't have to duplicate these fixes on the two current boards in the
tree and several forth coming boards that will also need the code.

Fixed RTC support that requires a dummy memory read on the P2P bridge
to unlock the RTC and setup the default of the RTC alarm registers to
match with a basic x86 style CMOS RTC.

Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure
the PCI IO space has been setup properly before we start poking ISA
registers at random locations.

David S. Miller 405849610f [MATH-EMU]: Fix underflow exception reporting.
The underflow exception cases were wrong.

This is one weird area of ieee1754 handling in that the underflow
behavior changes based upon whether underflow is enabled in the trap
enable mask of the FPU control register.  As a specific case the Sparc
V9 manual gives us the following description:

--------------------
If UFM = 0:     Underflow occurs if a nonzero result is tiny and a
                loss of accuracy occurs.  Tininess may be detected
                before or after rounding.  Loss of accuracy may be
                either a denormalization loss or an inexact result.

If UFM = 1:     Underflow occurs if a nonzero result is tiny.
                Tininess may be detected before or after rounding.
--------------------

What this amounts to in the packing case is if we go subnormal,
we set underflow if any of the following are true:

1) rounding sets inexact
2) we ended up rounding back up to normal (this is the case where
   we set the exponent to 1 and set the fraction to zero), this
   should set inexact too
3) underflow is set in FPU control register trap-enable mask

The initially discovered example was "DBL_MIN / 16.0" which
incorrectly generated an underflow.  It should not, unless underflow
is set in the trap-enable mask of the FPU csr.

Another example, "0x0.0000000000001p-1022 / 16.0", should signal both
inexact and underflow.  The cpu implementations and ieee1754
literature is very clear about this.  This is case #2 above.

However, if underflow is set in the trap enable mask, only underflow
should be set and reported as a trap.  That is handled properly by the
prioritization logic in

arch/sparc{,64}/math-emu/math.c:record_exception().

Based upon a report and test case from Jakub Jelinek.

Andrew Burgess e8c59c0cf9 [IA64] Failure to grow RBS
There is a bug in the ia64_do_page_fault code that can cause a failure
to grow the register backing store, or any mapping that is marked as
VM_GROWSUP if the mapping is the highest mapped area of memory.

When the address accessed is below the first mapping the previous mapping
is returned as NULL, and this case is handled.  However, when the address
accessed is above the highest mapping the vma returned is NULL, this
case is not handled correctly, and it fails to spot that this access
might require an existing mapping to grow upwards.

The core cpufreq code doesn't appear to understand returning -EAGAIN
for the get() function of the cpufreq_driver.  If PAL_GET_PSTATE returns
-1, such as when running on Xen, scaling_cur_freq is happy to return
4294967285 kHz (ie. (unsigned)-11).  The other drivers appear to return
0 for a failure, and doing so gives me the max frequency from
scaling_cur_frequency and "<unknown>" from cpuinfo_cur_frequency.  I
believe that's the desired behavior.

Haavard Skinnemoen cca67164bb [AVR32] Define mmiowb()
Add empty definition of mmiowb() since some drivers need it. Uncached
writes are strongly ordered on AVR32. They may be delayed if the
dcache is busy doing a writeback, but AFAICT that's not what this
macro is supposed to deal with, at least on UP systems.

We might have to revisit this definition when a SMP-capable AVR32 CPU
comes along, depending on how the busses and cache coherency stuff
end up being implemented.

Haavard Skinnemoen 6f834197a7 [AVR32] Fix bogus pte_page() definition
The current definition of pte_page() masks out valid bits from the
physical address, causing vmalloc_to_page() to misbehave. This may
lead to everything from mmap() silently accessing the wrong data to
"invalid pte" errors dumped by the kernel.

Also remove the now-unused definition of PTE_PHYS_MASK.

Thanks to Matteo Vit for discovering this bug.

Haavard Skinnemoen e7f3bac95e [AVR32] Simplify pte_alloc_one{,_kernel}
There's really no need to retry an allocation with __GFP_REPEAT set.
Also, use get_zeroed_page() and __GFP_ZERO to eliminate the extra call
to clear_page() afterwards.

Haavard Skinnemoen 54bb69e250 [AVR32] Wire up i2c-gpio on the ATNGW100 board
The NGW100 has a board controller which is hooked up to the TWI lines
on AP7000. Since the TWI driver isn't in mainline, use the i2c-gpio
driver in the mean time.

David Brownell ad93ab0a6e [AVR32] leds-gpio for stk1000
Add GPIO led support: J2 to either block of LEDs on the STK1000.

This uses the new LEDS_GPIO driver, and sets up a heartbeat trigger by
default ... either bright (!!) amber, or a more interesting purple.

Adjust libata to ignore errors after spinup

This patch is to ignore errors from the spinup attempt if the drive is

Sergei Shtylyov 80b8987c8f pata_hpt{37x|3x2n}: fix clock reporting (take 2)
Fix several inconsistencies in these drivers WRT reporting the clocks:

- when using DPLL mode, 'pata_hpt37x' driver reported the DPLL frequency as the
  PCI clock -- make it properly report both clocks and add the same ability to
  the 'pata_hpt3x2n' driver;

- both drivers sometimes use "pata_hpt3*:" and sometimes "hpt3*:" in the
  messages -- make them use only the former one;

- the message about failed DPLL stablizatios deserves KERN_ERR and a bang. :-)
