Fix the usage of CONFIG_SERIAL_SAMSUNG_UARTS in several places
in the kernel where it had been missed. This finishes fixing a
long standing issue where S3C2443 and S3C64XX could not use the

SHWT value is used as address valid to -CSx assertion and -CSx to -DIOx
assertion setup time, and contrarywise, -DIOx to -CSx release and -CSx
release to address invalid hold time, so it actualy applies 4 times and
so constitutes -DIOx recovery time. Check requirement of the recovery
time and cycle time. Also check SHWT maximum value.

As it is, all instances of ->release() for files that have ->fasync()
need to remember to evict file from fasync lists; forgetting that
creates a hole and we actually have a bunch that *does* forget.
So let's keep our lives simple - let __fput() check FASYNC in
file->f_flags and call ->fasync() there if it's been set. And lose that
crap in ->release() instances - leaving it there is still valid, but we
don't have to bother anymore.

Impact: optimize/clean-up the IO mapping implementation of the i915 DRM driver
Switch the i915 device aperture mapping to the io-mapping interface, taking
advantage of the cleaner API to extend it across all of the mapping uses,
including both pwrite and relocation updates.
This dramatically improves performance on 64-bit kernels which were using
the same slow path as 32-bit non-HIGHMEM kernels prior to this patch.

libata currently imposes a UDMA5 max transfer rate and 200 sector max
transfer size for SATA devices that sit behind a pata-sata bridge. Lots
of devices have known good bridges that don't need this limit applied.
The MTRON SSD disks are such devices. Transfer rates are increased by
20-30% with the restriction removed.
So add a "blacklist" entry for the MTRON devices, with a flag indicating
that the bridge is known good.

5287 used to be treated as vt6420 but it didn't work. It's new family
of controllers called vt8251 which hosts four SATA ports as M/S of the
two ATA ports. This configuration is rather peculiar in that although
the M/S devices are on the same port, each have its own SCR (or
equivalent link status/control) registers which screws up the
port-link-device hierarchy assumed by libata. Another controller
which falls into this category is ata_piix w/ SIDPR access.
libata now has facility to deal with this class of controllers named
slave_link. A low level driver for such controllers can just call
ata_slave_link_init() on the respective ports and libata will handle
all the difficult parts like following up with single SRST after
hardresetting both ports.
This patch creates new controller class vt8251, implements slave_link
aware init sequence and config space based SCR access for it and moves
5287 to the new class.
This patch is based on Joseph Chan's larger patch which was created
before slave_link was implemented in libata.

In ata_tf_to_lba48(), when evaluating
(tf->hob_lbal & 0xff) << 24
the expression is promoted to signed int (since int can hold all values
of u8). However, if hob_lbal is 128 or more, then it is treated as a
negative signed value and sign-extended when promoted to u64 to | into
sectors, which leads to the MSB 32 bits of section getting set
incorrectly.
For example, Phillip O'Donnell <phillip.odonnell@gmail.com> reported
that a 1.5GB drive caused:
ata3.00: HPA detected: current 2930277168, native 18446744072344861488
where 2930277168 == 0xAEA87B30 and 18446744072344861488 == 0xffffffffaea87b30
which shows the problem when hob_lbal is 0xae.
Fix this by adding a cast to u64, just as is used by for hob_lbah and
hob_lbam in the function.

Currently, the numa_node of OF-devices will be overwritten during
device_register, which simply sets the node to -1. On cell machines,
this means that devices can't find their IOMMU, which is referenced
through the device's numa node.
Set the numa node for OF devices with no parent, and use the
lower-level device_initialize and device_add functions, so that the
node is preserved.
We can remove the call to set_dev_node in of_device_alloc, as it
will be overwritten during register.

The init_phy() function attaches to the PHY, then configures the
SerDes<->TBI link (in SGMII mode). The TBI is on the MDIO bus with the PHY
(sort of) and is accessed via the gianfar's MDIO registers, using the
functions gfar_local_mdio_read/write(), which don't do any locking.
The previously attached PHY will start a work-queue on a timer, and
probably an irq handler as well, which will talk to the PHY and thus use
the MDIO bus. This uses phy_read/write(), which have locking, but not
against the gfar_local_mdio versions.
The result is that PHY code will try to use the MDIO bus at the same time
as the SerDes setup code, corrupting the transfers.
Setting up the SerDes before attaching to the PHY will insure that there is
no race between the SerDes code and *our* PHY, but doesn't fix everything.
Typically the PHYs for all gianfar devices are on the same MDIO bus, which
is associated with the first gianfar device. This means that the first
gianfar's SerDes code could corrupt the MDIO transfers for a different
gianfar's PHY.
The lock used by phy_read/write() is contained in the mii_bus structure,
which is pointed to by the PHY. This is difficult to access from the
gianfar drivers, as there is no link between a gianfar device and the
mii_bus which shares the same MDIO registers. As far as the device layer
and drivers are concerned they are two unrelated devices (which happen to
share registers).
Generally all gianfar devices' PHYs will be on the bus associated with the
first gianfar. But this might not be the case, so simply locking the
gianfar's PHY's mii bus might not lock the mii bus that the SerDes setup
code is going to use.
We solve this by having the code that creates the gianfar platform device
look in the device tree for an mdio device that shares the gianfar's
registers. If one is found the ID of its platform device is saved in the
gianfar's platform data.
A new function in the gianfar mii code, gfar_get_miibus(), can use the bus
ID to search through the platform devices for a gianfar_mdio device with
the right ID. The platform device's driver data is the mii_bus structure,
which the SerDes setup code can use to lock the current bus.
