Commit 9ee51f01eee8 (tty: serial/samsung: make register definitions
global) removed the S3C2410_PA_UARTX defines that the newly merged
s3c2416 dt support still expected.
So update mach-s3c2416-dt.c to use the S3C24XX_PA_UART constant until
we have support for the common clock framework the the s3c2416-dt.

Since uart_base can be set dynamically in arch_detect_cpu(), there is no
need to have a copy of all code locally, just to override UART base
address.
This patch removes any duplicate code in uncompress.h variant of s5p64x0
and implements proper arch_detect_cpu() function to initialize UART with
SoC-specific parameters.
While at it, replace hard-coded register address with macro.

For mach-exynos, uart_base is a pointer and the value is calculated
in the machine folder. For other machines, uart_base is defined as
a macro in platform directory. For symmetry, the uart_base macro
definition is removed and the uart_base calculation is moved to
specific machine folders.
This would help us consolidating uncompress subroutine for s5p64x0.

Currently, pcibios_resource_to_bus() and pcibios_bus_to_resource()

So we remove pci_window in pci_controller and embed hostbridge resource

Joshua reported: Commit cd7b304dfaf1 (x86, range: fix missing merge
during add range) broke mtrr cleanup on his setup in 3.9.5.
corresponding commit in upstream is fbe06b7bae7c.
The reason is add_range_with_merge could generate blank spot.
We could avoid that by searching new expanded start/end, that
new range should include all connected ranges in range array.
At last add the new expanded start/end to the range array.
Also move up left array so do not add new blank slot in the
range array.
-v2: move left array to avoid enhance add_range()
-v3: include fix from Joshua about memmove declaring when
DYN_DEBUG is used.

Joshua reported: Commit cd7b304dfaf1 (x86, range: fix missing merge
during add range) broke mtrr cleanup on his setup in 3.9.5.
corresponding commit in upstream is fbe06b7bae7c.
*BAD*gran_size: 64K chunk_size: 16M num_reg: 6 lose cover RAM: -0G
https://bugzilla.kernel.org/show_bug.cgi?id=59491
So it rejects new var mtrr layout.
It turns out we have some problem with initial mtrr range retrieval.
The current sequence is:
x86_get_mtrr_mem_range
==> bunchs of add_range_with_merge
==> bunchs of subract_range
==> clean_sort_range
add_range_with_merge for [0,1M)
sort_range()
add_range_with_merge could have blank slots, so we can not just
sort only, that will have final result have extra blank slot in head.
So move that calling add_range_with_merge for [0,1M), with that we
could avoid extra clean_sort_range calling.

This patch adds selection of CONFIG_SPARSE_IRQ for ARCH_EXYNOS, since it
is required by multiplatform and allows to remove the legacy mach/irqs.h
header.
To make this possible, a dummy IRQ_EINT_BIT macro is added to pm-core.h
header to allow plat-samsung/pm.c compile. This macro is irrelevant for
Exynos and will be removed after reworking Samsung pm code for
multiplatform compatibility.

umount is in process.

umount /cgroup
And this:
modprobe cfq-iosched

RTC support for EXYNOS5250.
