arm: plat-orion: fix address decoding when > 4GB is used
During the system initialization, the orion_setup_cpu_mbus_target()
function reads the SDRAM address decoding registers to find out how
many chip-selects of SDRAM have been enabled, and builds a small array
with one entry per chip-select. This array is then used by device
drivers (XOR, Ethernet, etc.) to configure their own address decoding
windows to the SDRAM.
However, devices can only access the first 32 bits of the physical
memory. Even though LPAE is not supported for now, some Marvell boards
are now showing up with 8 GB of RAM, configured using two SDRAM
address decoding windows: the first covering the first 4 GB, the
second covering the last 4 GB. The array built by
orion_setup_cpu_mbus_target() has therefore two entries, and device
drivers try to set up two address decoding windows to the
SDRAM. However, in the device registers for the address decoding, the
base address is only 32 bits, so those two windows overlap each other,
and the devices do not work at all.
This patch makes sure that the array built by
orion_setup_cpu_mbus_target() only contains the SDRAM decoding windows
that correspond to the first 4 GB of the memory. To do that, it
ignores the SDRAM decoding windows for which the 4 low-order bits are
not zero (the 4 low-order bits of the base register are used to store
bits 32:35 of the base address, so they actually indicate whether the
base address is above 4 GB).
This patch allows the newly introduced armada-xp-gp board to properly
operate when it is mounted with more than 4 GB of RAM. Without that,
all devices doing DMA (for example XOR and Ethernet) do not work at
all.

When DT support for kirkwood was first introduced, there was no clock

Unfortunately, on kirkwood, with minimal config or all module configs,
clock-frequency breaks booting because of_serial doesn't consume the
gate_clk when clock-frequency is defined.
The end result on kirkwood is that runit gets gated, and then the boot
fails when the kernel tries to write to the serial port.
Fix the issue by removing the clock-frequency parameter from all
kirkwood dts files.

issues or other problems.
scrub does not yet correct errors on raid5/6 either.
Josef has another pass at fsync performance. The big change here is
to combine waiting for metadata with waiting for data, which is a big
latency win. It is also step one toward using atomics from the
hardware during a commit.
Mark Fasheh has a new way to use btrfs send/receive to send only the

arch/metag/include/asm/irqflags.h:86: error: implicit declaration of function 'preempt_enable_no_resched'
However <linux/preempt.h> cannot be easily included from
<asm/irqflags.h> as it can cause circular include dependencies in the
!SMP case, and potentially in the SMP case in the future. Therefore move
the SMP implementation of arch_local_irq_enable() into traps.c and use
an inline version of get_trigger_mask() which is also defined in traps.c
for SMP.
This adds an extra layer of function call / stack push when
preempt_disable needs to call other functions, however in the
non-preemptive SMP case it should be about as fast, as it was already
calling the get_trigger_mask() function which is now used inline.

genksyms: fix metag symbol prefix on crc symbols
Meta uses symbol prefixes, so add "metag" to the list of architectures
to set the mod_prefix to "_" for. This fixes __crc_* symbols to add the
extra underscore to match _CRC_SYMBOL macro in <linux/export.h> and so
that modpost finds them.

Convert hugetlb_get_unmapped_area_new_pmd() to use vm_unmapped_area()

removed after other architectures have already been converted:

metag: make TXPRIVEXT bits explicit
Define PRIV_BITS using explicit constants from <asm/metag_regs.h> rather
than with a hard coded value. This also adds a couple of missing
definitions for the TXPRIVEXT priv bits for protecting writes to TXTIMER
and the trace registers.

metag: Add JTAG Debug Adapter (DA) support
Add basic JTAG Debug Adapter (DA) support so that drivers which
communicate with the DA can detect whether one is actually present
(otherwise the target will halt indefinitely).
This allows the metag_da TTY driver and imgdafs filesystem driver to be
built, updates defconfigs, and sets up the metag_da console early if
it's configured in.
