This patch fix consistent code which had problems with consistent_free
function.
I am not sure if we need to call flush_tlb_all after it but it keeps
tlbs synced.
I added noMMU and MMU version together.
Uncached shadow feature is not tested.

Current implementation doesn't handle dcache_line_length
correctly that's why is better to use generic memcpy.
Cache optimized function could be good way howto improve
performance but must be based on benchmarking not blind
function like this.

As explained in commit 1c0fe6e3bd, we want to call the architecture independent
oom killer when getting an unexplained OOM from handle_mm_fault, rather than
simply killing current.

Remove section mismatch - based on ppc aproach.
WARNING: vmlinux.o(.text+0x64834): Section mismatch in reference
from the function __pte_alloc_kernel() to the function .init.text:early_get_page()
The function __pte_alloc_kernel() references
the function __init early_get_page().
This is often because __pte_alloc_kernel lacks a __init
annotation or the annotation of early_get_page is wrong.

bus->resource[] refs
This change should be part of 89a74ecccd1f78e51faf6287e5c0e93a92ac096e
Origin description:
PCI: add pci_bus_for_each_resource(), remove direct bus->resource[] refs
No functional change; this converts loops that iterate from 0 to
PCI_BUS_NUM_RESOURCES through pci_bus resource[] table to use the
pci_bus_for_each_resource() iterator instead.
This doesn't change the way resources are stored; it merely removes
dependencies on the fact that they're in a table.

When we compare the devices DMA mask to the amount of memory we need to
make sure we treat the DMA mask as an address boundary. For example if
the DMA_MASK(32) and we have 4G of memory we'd incorrectly set the dma
ops to swiotlb. We need to add one to the dma mask when we convert it.

But asm/io.h was only included indirectly - and on some configs

This patch fixes the preempt leak in the cpuidle path invoked from
cpu-hotplug. The fix is suggested by Russell King and is based
on x86 idea of calling init_idle() on the idle task when it's
re-used which also resets the preempt count amongst other things

The -mfix-loongson2f-jump option provided by latest CVS binutils have fixed
the out-of-order issue of Loongson-2F described in chapter 15 of the
Loongson2F User Manual [1, 2], but introduced some problems.
The option changes all of the jump target to "addr & 0xcfffffff" through the
at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is
wrong. Avoids the problem via telling the assembler to not use the $at
register.

With the "Fixups of Loongson2F" patch [1] having been applied to binutils
for binutils 2.20.1 we now can use it's time to enable the options provided
by the patch to compile the kernel.
Without these fixups, the system may hang if the erratum is triggered.
For more information on these fixups please refer to the following

As documented in the Loongson 2F User Manual [2, 3], the old Loongson2F
series (2F01 / 2F02) have the NOP & JUMP issues which requires workarounds
in the kernel and binutils. This issue has been rectified in Loongson 2F
series 2F03 so no workarounds needed.
Now that the workarounds [1] adding the the -mfix-loongson2f-nop and
-mfix-loongson2f-jump options have been comitted to the binutils the CVS
repository), we can add the workarounds in the kernel.
The workarounds have no significant side effect on the system but may
decrease performance so we control them through a a new
CPU_LOONGSON2F_WORKAROUNDS config option allowing the users to only enable
it as necessary.

"MIPS: Calculate proper ebase value for 64-bit kernels"
9af43ea080dd5d6c7b34f38261780e5dd43537bc (lmo) rsp.
f6be75d03c8870be91e6e2a195648ece04b6bb16 (kernel.org) broke some 64-bit
MIPS systems.
Before this we were using XKPHYS/cached as ebase and computed the uncached
xphsys/unchached address for that area. After that commit ebase became a
32-bit compat address and convert does not work anymore. We now should use
CKSEG1 for this. CKSEG1ADDR does just that in 32-bit and 64-bit.
