Add the xstate regset support which helps extend the kernel ptrace and the
core-dump interfaces to support AVX state etc.
This regset interface is designed to support all the future state that gets
supported using xsave/xrstor infrastructure.
Looking at the memory layout saved by "xsave", one can't say which state
is represented in the memory layout. This is because if a particular state is
in init state, in the xsave hdr it can be represented by bit '0'. And hence
we can't really say by the xsave header wether a state is in init state or
the state is not saved in the memory layout.
And hence the xsave memory layout available through this regset
interface uses SW usable bytes [464..511] to convey what state is represented
in the memory layout.
First 8 bytes of the sw_usable_bytes[464..467] will be set to OS enabled xstate
mask(which is same as the 64bit mask returned by the xgetbv's xCR0).
The note NT_X86_XSTATE represents the extended state information in the
core file, using the above mentioned memory layout.

Simplify setup_node_mem: don't use bootmem from other node, instead
just find_e820_area in early_node_mem.
This keeps the boundary between early_res and boot mem more clear, and
lets us only call early_res_to_bootmem() one time instead of for all
nodes.

We have almost the same code for mtrr cleanup and amd_bus checkup, and
this code will also be used in replacing bootmem with early_res,
so try to move them together and reuse it from different parts.
Also rename update_range to subtract_range as that is what the

Keep chip_data in create_irq_nr and destroy_irq.
When two drivers are setting up MSI-X at the same time via
pci_enable_msix() there is a race. See this dmesg excerpt:
[ 85.170610] ixgbe 0000:02:00.1: irq 97 for MSI/MSI-X
[ 85.170611] alloc irq_desc for 99 on node -1

[ 85.170626] alloc irq_desc for 101 on node -1
[ 85.170628] igb 0000:08:00.1: irq 100 for MSI/MSI-X

[ 85.170639] alloc irq_2_iommu on node -1
[ 85.170646] BUG: unable to handle kernel NULL pointer dereference
at 0000000000000088
As you can see igb and ixgbe are both alternating on create_irq_nr()
via pci_enable_msix() in their probe function.
ixgbe: While looping through irq_desc_ptrs[] via create_irq_nr() ixgbe
choses irq_desc_ptrs[102] and exits the loop, drops vector_lock and
calls dynamic_irq_init. Then it sets irq_desc_ptrs[102]->chip_data =
NULL via dynamic_irq_init().
igb: Grabs the vector_lock now and starts looping over irq_desc_ptrs[]
via create_irq_nr(). It gets to irq_desc_ptrs[102] and does this:
cfg_new = irq_desc_ptrs[102]->chip_data;
if (cfg_new->vector != 0)
continue;
This hits the NULL deref.
Another possible race exists via pci_disable_msix() in a driver or in
the number of error paths that call free_msi_irqs():
destroy_irq()
dynamic_irq_cleanup() which sets desc->chip_data = NULL
...race window...
desc->chip_data = cfg;
Remove the save and restore code for cfg in create_irq_nr() and
destroy_irq() and take the desc->lock when checking the irq_cfg.

As reported by Maxime Bizon, the commit "MIPS: PowerTV: Fix support for
timer interrupts with > 64 external IRQs" have broken the r4k timer
since it didn't initialize the cp0_compare_irq_shift variable used in
c0_compare_int_pending() on the architectures whose cpu_has_mips_r2 is
false.
This patch fixes it via initializing the cp0_compare_irq_shift as the
cp0_compare_irq used in the old c0_compare_int_pending().

This patch fixes the power LED on DNS-323 revision A1, and adds timer
support for (hopefully) both A1 and B1 revisions.
Power LED on revision A1 is active low and also requires GPIO 4 to be
low to work.
Tested on my DNS-323 revision A1.
I have set the default trigger to timer as that replicates the
behaviour of the original firmware, userspace can change the trigger
at the end of the boot process providing a useful indication that
booting has completed.

This patch adds NOR FLASH MTD support to the Katmai (440SPe) dts file.
For this the OPB ranges address is mapped differently (base 0x00000000
-> 0xe0000000). This results in the address being identical to the lower
32bit of its physical address. This is needed for the MTD mapping to work
correctly, since U-Boot will insert the physical addresses of the EBC
chip selects into the EBC ranges property. This is the way its done in
most other 4xx dts files as well.
Additionally with a small whitespace cleanup.
