sparc64: Fix PCI resource mapping on sparc64
There is a problem discovered in recent versions of ATI Mach64 driver
in X.org on sparc64 architecture. In short, the driver fails to mmap
MMIO aperture (PCI resource #2).
I've found that kernel's __pci_mmap_make_offset() returns EINVAL. It
checks whether user attempts to mmap more than the resource length,
which is 0x1000 bytes in our case. But PAGE_SIZE on SPARC64 is 0x2000
and this is what actually is being mmaped. So __pci_mmap_make_offset()
failed for this PCI resource.

x86: Clean up late e820 resource allocation
This makes the late e820 resources use 'insert_resource_expand_to_fit()'
instead of doing a 'reserve_region_with_split()', and also avoids
marking them as IORESOURCE_BUSY.
This results in us being perfectly happy to use pre-existing PCI
resources even if they were marked as being in a reserved region, while
still avoiding any _new_ allocations in the reserved regions. It also
makes for a simpler and more accurate resource tree.
Example resource allocation from Jonathan Corbet, who has firmware that
has an e820 reserved entry that covered a big range (
e0000000-
fed003ff),
and that had various PCI resources in it set up by firmware.
With old kernels, the reserved range would force us to re-allocate all
pre-existing PCI resources, and his reserved range would end up looking
like this:
e0000000-
fed003ff : reserved
fec00000-
fec00fff : IOAPIC 0
fed00000-
fed003ff : HPET 0
where only the pre-allocated special regions (IOAPIC and HPET) were kept
around.
With 2.6.28-rc2, which uses 'reserve_region_with_split()', Jonathan's
resource tree looked like this:
e0000000-
fe7fffff : reserved
fe800000-
fe8fffff : PCI Bus 0000:01
fe800000-
fe8fffff : reserved

and because the reserved entry had been split and moved into the
individual resources, and because it used the IORESOURCE_BUSY flag, the
drivers that actually wanted to _use_ those resources couldn't actually
attach to them:

reserve_region_with_split: Fix GFP_KERNEL usage under spinlock
This one apparently doesn't generate any warnings, because the function
is only used during system bootup, when the warnings are disabled. But
it's still very wrong.
The __reserve_region_with_split() function is called with the
resource_lock held for writing, so it must only ever do GFP_ATOMIC

register_pernet_gen_device() can't be used is nf_conntrack_pptp module is

Right now, proto_gre_net_exit() is called before nf_conntrack_pptp_net_exit().
The former shutdowns and frees GRE piece of netns, however the latter
absolutely needs it to flush keymap. Oops is inevitable.
Switch to shiny new register_pernet_gen_subsys() to get correct ordering in

libata: add whitelist for devices with known good pata-sata bridges
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.

sata_via: fix support for 5287
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.

libata: Avoid overflow in ata_tf_to_lba48() when tf->hba_lbal > 127
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.

The size of the pm_signal_local array should be equal to the

array is of size 4 (NR_PHYS_CTRS) but being indexed by a for
loop from 0 to 7 (NUM_SPUS_PER_NODE). This could potentially
