commit 4e34e719e45, that takes the ACL checks to common code,
accidentely broke the build when CONFIG_FS_POSIX_ACL is not set:
CC fs/xfs/linux-2.6/xfs_iops.o
fs/xfs/linux-2.6/xfs_iops.c:1025:14: error: ‘xfs_get_acl’ undeclared here (not in a function)
Fix this by declaring xfs_get_acl a static inline function.

Fixes a regression caused by b5695d04634fa4ccca7dcbc05bb4a66522f02e0b
Kernel keyring keys containing eCryptfs authentication tokens should not
be write locked when calling out to ecryptfsd to wrap and unwrap file
encryption keys. The eCryptfs kernel code can not hold the key's write
lock because ecryptfsd needs to request the key after receiving such a
request from the kernel.
Without this fix, all file opens and creates will timeout and fail when
using the eCryptfs PKI infrastructure. This is not an issue when using
passphrase-based mount keys, which is the most widely deployed eCryptfs
configuration.

decode_bar() and pci_calc_resource_flags() both looked at the PCI BAR
type information, and it's simpler to just do it all in one place.
decode_bar() sets IORESOURCE_IO, IORESOURCE_MEM, and IORESOURCE_MEM_64
as appropriate, so res->flags contains all the information pci_bar_type
does, so we don't need to test the pci_bar_type return value.
decode_bar() used to return pci_bar_type, which we no longer need. We
can simplify it a bit by returning the struct resource flags rather than
updating them internally.
In pci_update_resource(), there's no need to decode the BAR type bits
again; we can just test for IORESOURCE_MEM_64 directly.

This fixes a minor regression where broken PCI devices that use the
reserved "11" memory BAR type worked before e354597cce but not after.
The low four bits of a memory BAR are "PTT0" where P=1 for prefetchable
BARs, and TT is as follows:
00 32-bit BAR, anywhere in lower 4GB
01 anywhere below 1MB (reserved as of PCI 2.2)
10 64-bit BAR
11 reserved
Prior to e354597cce, we treated "0100" as a 64-bit BAR and all others,
including prefetchable 64-bit BARs ("1100") as 32-bit BARs. The e354597cce
fix, which appeared in 2.6.28, treats "x1x0" as 64-bit BARs, so the
reserved "x110" types are treated as 64-bit instead of 32-bit.
This patch returns to treating the reserved "11" type as a 32-bit BAR and
adds a warning if we see it.
It also logs a note if we see a 1M BAR. This is not a warning, because
such hardware conforms to pre-PCI 2.2 spec, but I think it's worth noting
because Linux ignores the 1M restriction if it ever has to assign the BAR.

When setting the PCI-E MRRS, pcie_set_readrq queries the current
settings via a pci_read_config_word call but writes the modified result
via a pci_write_config_dword. This results in writing 16 more bits than
were queried.
Also, the function description comment is slightly incorrect.

Naoki Yanagimoto reported that configuration read on some hot-added
PCIe device returns invalid value. This patch fixes this problem.
According to the PCIe spec, software must wait for at least 1 second
to judge if the hot-added device is broken after Data Link Layer State
Changed Event. This patch changes pciehp driver to wait for 1 second
after the Data Link Layer State Changed Event is detected before
initiating a configuration access instead of 100 ms.

Commit 6e8af08dfa40b747002207d3ce8e8b43a050d99f enables pci=bfsort on
future Dell systems. But the identification string 'Dell System' matches
on already existing whitelist, which do not have SMBIOS type 0xB1,
causing pci=bfsort not being set on existing whitelist.
This patch fixes the regression by moving the type 0xB1 check beyond the
existing whitelist so that existing whitelist is walked before.

The function pci_enable_ari() may mistakenly set the downstream port
of a v1 PCIe switch in ARI Forwarding mode. This is a PCIe v2 feature,
and with an SR-IOV device on that switch port believing the switch above
is ARI capable it may attempt to use functions 8-255, translating into
invalid (non-zero) device numbers for that bus. This has been seen
to cause Completion Timeouts and general misbehaviour including hangs
and panics.

Aside of the usual motivation for constification, this function has a
history of being abused a hook for interrupt and other fixups so I turned
this function const ages ago in the MIPS code but it should be done
treewide.
Due to function pointer passing in varous places a few other functions
had to be constified as well.

Without this change, the majority of the raw PCI config space access
functions silently ignore a non-zero segment argument, which is
certainly wrong.
Apart from pci_direct_conf1, all other non-MMCFG access methods get
used only for non-extended accesses (i.e. assigned to raw_pci_ops
only). Consequently, with the way raw_pci_{read,write}() work, it would
be a coding error to call these functions with a non-zero segment (with
the current call flow this cannot happen afaict).
The access method 1 accessor, as it can be used for extended accesses
(on AMD systems) instead gets checks added for the passed in segment to
be zero. This would be the case when on such a system having multiple
PCI segments (don't know whether any exist in practice) MMCFG for some
reason is not usable, and method 1 gets selected for doing extended
accesses. Rather than accessing the wrong device's config space, the
function will now error out.
v2: Convert BUG_ON() to WARN_ON(), and extend description as per Ingo's
request.

Host bridge windows are top-level resources, so if we find a host bridge
window conflict, it's probably with a hard-coded legacy reservation.
Moving host bridge windows is theoretically possible, but we don't support
it; we just ignore windows with conflicts, and it's not worth making this
a user-visible error.

re-scanning PCI
When hot-plugging a root bridge, we always prevent assigning a bus number
that already exists. This makes sure we don't step over an existing bus.
But sometimes we only remove PCI device in PCI hieratchy of OS, i,e.
echo 1 > /sys/bus/pci/devices/.../remove
but actually don't hotplug this device out the platform, so in this case
we still should re-scan this bus to enumerate this device when re-scanning
PCI again.

In addition to native PCIe AER, now APEI (ACPI Platform Error
Interface) GHES (Generic Hardware Error Source) can be used to report
PCIe AER errors too. To add support to APEI GHES PCIe AER recovery,
aer_recover_queue is added to export the recovery function in native
PCIe AER driver.
Recoverable PCIe AER errors are reported via NMI in APEI GHES. Then
APEI GHES uses irq_work to delay the error processing into an IRQ
handler. But PCIe AER recovery can be very time-consuming, so
aer_recover_queue, which can be used in IRQ handler, delays the real
recovery action into the process context, that is, work queue.

Direct access is needed in mmconf mode too. There are two reasons:
1. we need it to access first 256 bytes. We have bug before that
using mmconf to access pci config space hangs system (when
resizing BARs), so we use type1 config for legacy config space.
2. when doing mmconfg bar checking, we need access ACPI _CRS,
which might access PCI config space.

While it's declared static, etags points you to the wrong function

If you trust etags and oversee the static declaration (what happened

Fix this by making sure struct multicall_entry has a declaration in
scope at all times, and don't bother compiling xen/trace.c when tracing
is disabled.

instead of reading the registers everytime
the current implementation respect the following constrain:
- allow 1 to n soc to be enabled
- allow to have a virtual cpu type and subtype
- always detect the cpu type and subtype and report it
- detect if the soc support is enabled
- prepare for sysfs export support
- drop soc specific code via compiler when the soc not enabled
(via cpu_is_xxx)
Today if we read the exid we will have the same value for 9g35 and 9m11
and we will need to check the cidr too
with the new implementation we just need to check the soc subtype
this will also allow to have specific virtual subtype for rm9200 which the
board will have to specify via at91rm9200_set_type(int) as we have no way to
detect it.
this implementation is inspired by the SH cpu detection support

On all at91 except rm9200 and x40 have the System Controller starts
at address 0xffffc000 and has a size of 16KiB.
On rm9200 it's start at 0xfffe4000 of 111KiB with non reserved data starting
at 0xfffff000
This patch removes the individual definitions of AT91_BASE_SYS and
replaces them with a common version at base 0xfffffc000 and size 16KiB
and map the same memory space

It might be not good to use software defined version to identify sdma
device type, when hardware does not define such version. Instead,
soc name is stable enough to define the device type.
The patch uses platform_device_id rather than version number passed
by platform data to identify sdma device type/version.

Neither platform based nor dt based device needs to pass the parent
to sdhci_alloc_host. There is no difference between platform and dt
on this point.
The patch makes the change to pass device itself than its parent to
sdhci_alloc_host for dt case too. Otherwise the probe function of
sdhci based drivers which is shared between platform and dt will
fail on dt case.
