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.

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.

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.

d44a65f7bb pata_hpt37x: actually clock HPT374 with 50 MHz DPLL (take 2)
The DPLL tuning code always set up it for 66 MHz due to wrong UltraDMA mask
including mode 5 used to check for the necessity of 66 MHz clocking -- this
caused 66 MHz clock to be used for HPT374 chip that does not tolerate it.
While fixing this, also remove PLL mode from the TODO list -- I don't think
it's still a relevant item.

be456b77ff pata_artop: fix UDMA5 for AEC6280[R] and UDMA6 for AEC6880[R]
Maximum supported UDMA mode for AEC6280[R] is UDMA5 (not UDMA4)
and for AEC6880[R] it is UDMA6 (not UDMA5):

* Fix the problem by adding missing struct ata_port_info to artop_init_one().

* Use the right naming (s/626/628/).

* Bump driver version.

Fixes IDE->libata regression, problem was never present in IDE aec62xx driver.

2de69124e8 [POWERPC] ps3: Fix no storage devices found
Fix probing of PS3 storage devices: in the success case, we should set
`error' to zero, not `result'.

Without this patch no storage devices are found.

55a910a81d [POWERPC] Fix for assembler -g
ppc64 does the unusual thing of using #include on a compiler-generated
assembly file (lparmap.s) from an assembly source file (head_64.S).
This runs afoul of my recent patch to pass -gdwarf2 to the assembler
under CONFIG_DEBUG_INFO.  This patch avoids the problem by disabling
DWARF generation (-g0) when producing lparmap.s.

aa1cf632bd [POWERPC] Fix small race in 44x tlbie function
The 440 family of processors don't have a tlbie instruction.  So, we
implement TLB invalidates by explicitly searching the TLB with tlbsx.,
then clobbering the relevant entry, if any.  Unfortunately the PID for
the search needs to be stored in the MMUCR register, which is also
used by the TLB miss handler.  Interrupts were enabled in _tlbie(), so
an interrupt between loading the MMUCR and the tlbsx could cause
incorrect search results, and thus a failure to invalide TLB entries
which needed to be invalidated.

This fixes the problem in both arch/ppc and arch/powerpc by inhibiting
interrupts (even critical and debug interrupts) across the relevant
instructions.
