1f80a67da2 microblaze: Fix pte_update function
Do not disable irq in asm but use irq macros.
Systems with MSR=0 couldn't use pte_update function
because msrclr was hardcoded.

658b368da1 microblaze: Fix asm/pgtable.h
Function ptep_test_and_clear_young have had wrong the first argument.
It is also necessary to add __HAVE macros for ptep_test_and_clear_young and
ptep_get_and_clear functions.

ece0e2b640 mm: remove pte_*map_nested()
Since we no longer need to provide KM_type, the whole pte_*map_nested()
API is now redundant, remove it.

f1525765fb microblaze: Fix consistent code
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.

a6475c1322 microblaze: Enable PCI, missing files
There are two parts of changes. The first is just enable
PCI in Makefiles and in Kconfig. The second is the rest of
missing files. I didn't want to add it with previous patch
because that patch is too big.

Current Microblaze toolchain has problem with weak symbols
that's why is necessary to apply this changes to be possible
to compile pci support.
Xilinx knows about this problem.

f14d6f7c31 microblaze: Add _PAGE_FILE macros to pgtable.h
We need to define _PAGE_FILE macro and change pte
functions. Microblaze use the same MMU as PowerPC
that's why we define _PAGE_FILE in the same style.
This change fixed remap_file_pages01 LTP test.

0c60155e14 microblaze: add a dummy pgprot_noncached
Some device drivers call this, so add a macro
that pretends to do this. Since there is no
MMU support, it won't actually result in an
uncached mapping, though.
