c132419e56 gianfar: Fix race in TBI/SerDes configuration
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.

|     x86: convert cpuinfo_x86 array to a per_cpu array

We've had an extra field in cpuinfo_x86 which is cpu_index.
Unfortunately, voyager has never initialised this, although the only
noticeable impact seems to be that /proc/cpuinfo shows all zeros for
the processor ids.

Anyway, fix this by initialising the boot CPU properly and setting the
index when the secondaries update.

9e41bff270 x86: fix /dev/mem mmap breakage when PAT is disabled
Impact: allow /dev/mem mmaps on non-PAT CPUs/platforms

Fix mmap to /dev/mem when CONFIG_X86_PAT is off and CONFIG_STRICT_DEVMEM is
off

mmap to /dev/mem on kernel memory has been failing since the
introduction of PAT (CONFIG_STRICT_DEVMEM=n case).   Seems like
the check to avoid cache aliasing with PAT is kicking in even
when PAT is disabled. The bug seems to have crept in 2.6.26.

This patch makes sure that the mmap to regular
kernel memory succeeds if CONFIG_STRICT_DEVMEM=n and
PAT is disabled, and the checks to avoid cache aliasing
still happens if PAT is enabled.

cea7e2dfde MIPS: Sort out CPU type to name translation.
As noticed by David Daney <ddaney@caviumnetworks.com>, the old long switch
statement did not comply with the Linux C coding style.  It was also yet
another place of code to be changed when adding a new processor type
leading to annoying bugs for example in /proc/cpuinfo.

Fixed by moving the setting of the CPU type string into the core of the
probing code and a few BUG_ON() test to ensure the CPU probing code indeed
did its job and removing multiple now redundant tests.

fe8b868ecc x86: remove debug code from arch_add_memory()
Impact: remove incorrect WARN_ON(1)

Gets rid of dmesg spam created during physical memory hot-add which
will very likely confuse users.  The change removes what appears to
be debugging code which I assume was unintentionally included in:

1d6cf1feb8 x86: start annotating early ioremap pointers with __iomem
Impact: some new sparse warnings in e820.c etc, but no functional change.

As with regular ioremap, iounmap etc, annotate with __iomem.

Fixes the following sparse warnings, will produce some new ones
elsewhere in arch/x86 that will get worked out over time.

arch/x86/mm/ioremap.c:402:9: warning: cast removes address space of expression
arch/x86/mm/ioremap.c:406:10: warning: cast adds address space to expression (<asn:2>)
arch/x86/mm/ioremap.c:782:19: warning: Using plain integer as NULL pointer

f96f57d91c x86: fix init_memory_mapping for [dc000000 - e0000000) - v2
Impact: change over-mapping to precise mapping, fix /proc/meminfo output

v2: fix less than 1G ram system handling

when gart aperture is 0xdc000000 - 0xe0000000
it return 0xc0000000 - 0xe0000000

that is not right.

this patch fix that will get exact mapping

on 256g sytem with that aperture after patch
