Here are a collection of small fixes tha have been gathered for
4.4-rc1. The only significant changes are those in PCI drivers
Kconfig, to use "depends on" instead of "select" for CONFIG_ZONE_DMA.
A reverse select is often more user-friendly, but in this case, it
makes hard to manage with the conflict with ZONE_DEVICE, so changed in
such a way for now.
Others are all small fixes and quirks: an error check in soundcore
reigster_chrdev(), HD-audio HDMI/DP phantom jack fix, Intel Broxton DP
quirk, USB-audio DSD device quirk, some constifications, etc.

ARC: cpu_relax() to be compiler barrier even for UP
ARC: use ASL assembler mnemonic
ARC: [arcompact] Handle bus error from userspace as Interrupt not exception
ARC: remove extraneous header include
ARCv2: lib: memcpy: use local symbols
cpu_relax() on ARC has been barrier only for SMP (and no-op for UP). Per
recent discussions, it is safer to make it a compiler barrier
unconditionally.

ARCompact and ARCv2 only have ASL, while binutils used to support LSL as
a alias mnemonic.
Newer binutils (upstream) don't want to do that so replace it.
Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
Bus errors from userspace on ARCompact based cores are handled by core
as a high priority L2 interrupt but current code treated it as interrupt
Handling an interrupt like exception is certainly not going to go unnoticed.
(and it worked so far as we never saw a Bus error from userspace until
IPPK guys tested a DDR controller with ECC error detection etc hence
needed to explicitly trigger/handle such errors)
- So move mem_service exception handler from common code into ARCv2 code.
- In ARCompact code, define mem_service as L2 interrupt handler which
just drops down to pure kernel mode and goes of to enqueue SIGBUS

Here's the branch of chrome platform changes for v4.4. Some have been queued
up for the full 4.3 release cycle since I forgot to send them in for that
round (rebased early on to deal with fixes conflicts).
Most of these enable EC communication stuff -- Pixel 2015 support, enabling
building for ARM64 platforms, and a few fixes for memory leaks.
There's also a patch in here to allow reading/writing the verified boot
context, which depends on a sysfs patch acked by Greg.

Pull SCSI target updates from Nicholas Bellinger:
"This series contains HCH's changes to absorb configfs attribute
->show() + ->store() function pointer usage from it's original
tree-wide consumers, into common configfs code.
It includes usb-gadget, target w/ drivers, netconsole and ocfs2
changes to realize the improved simplicity, that now renders the
original include/target/configfs_macros.h CPP magic for fabric drivers

And with common code in place, new configfs attributes can be added

Note, there are further improvements in-flight from other folks for
v4.5 code in configfs land, plus number of target fixes for post -rc1
code"

class tracing abstraction to account for the removal of the old
show_attribute and store_attribute methods in commit 517982229f
("configfs: remove old API") from this pull. As Alexander says about
that patch:
"There's no need to keep an extra wrapper structure per item and the
awkward show_attribute/store_attribute item ops are no longer needed.
This patch converts policy code to the new api, all the while making
the code quite a bit smaller and easier on the eyes.

Now that the xattr handler is passed to the xattr handler operations, we
can use the same get and set operations for the user, trusted, and security
xattr namespaces. In those namespaces, we can access the full attribute
name by "reattaching" the name prefix the vfs has skipped for us. Add a
xattr_full_name helper to make this obvious in the code.
For the "system.posix_acl_access" and "system.posix_acl_default"

specific flags value which the operations can use to disambiguate between
different handlers; some file systems use that to distinguish the xattr
namespace, for example. In some oprations, it would be useful to also have
access to the handler prefix. To allow that, pass a pointer to the handler
to operations instead of the flags value alone.

The vfs checks if a task has the appropriate access for get and set
operations, but it cannot do that for the list operation; the file system
must check for that itself.

Ubifs installs a security xattr handler in sb->s_xattr but doesn't use the
generic_{get,set,list,remove}xattr inode operations needed for processing
this list of attribute handlers; the handler is never called. Instead,
ubifs uses its own xattr handlers which also process security xattrs.
Remove the dead code.

When a filesystem that contains POSIX ACLs is mounted without ACL support
(-o noacl), the appropriate behavior is not to list any existing POSIX ACL
xattrs. The return value for list xattr handlers in this case is 0, not an
error code: several filesystems that use the POSIX ACL xattr handlers do
not expect the list operation to fail.
Symlinks cannot have ACLs, so posix_acl_xattr_list will never be called for
symlinks in the first place.

The get and set operations of the POSIX ACL xattr handlers failed to check
the attribute names, so all names with "system.posix_acl_access" or
"system.posix_acl_default" as a prefix were accepted. Reject invalid names
from now on.

Since 4.3 introduced devm_memremap_pages() the pfns handled by DAX may
optionally have a struct page backing. When a mapped pfn reaches
vmf_insert_pfn_pmd() it fails with a crash signature like the following:
kernel BUG at mm/huge_memory.c:905!
[..]
Call Trace:
[<ffffffff812a73ba>] __dax_pmd_fault+0x2ea/0x5b0
[<ffffffffa01a4182>] xfs_filemap_pmd_fault+0x92/0x150 [xfs]
[<ffffffff811fbe02>] handle_mm_fault+0x312/0x1b50
Fix this by falling back to 4K mappings in the pfn_valid() case. Longer
term, vmf_insert_pfn_pmd() needs to grow support for architectures that
can provide a 'pmd_special' capability.

- x86: work around two nasty cases where a benign exception occurs while
another is being delivered. The endless stream of exceptions causes an
infinite loop in the processor, which not even NMIs or SMIs can interrupt;
in the virt case, there is no possibility to exit to the host either.
- x86: support for Skylake per-guest TSC rate. Long supported by AMD,
the patches mostly move things from there to common arch/x86/kvm/ code.
- generic: remove local_irq_save/restore from the guest entry and exit
paths when context tracking is enabled. The patches are a few months
old, but we discussed them again at kernel summit. Andy will pick up
from here and, in 4.5, try to remove it from the user entry/exit paths.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull second batch of kvm updates from Paolo Bonzini:
"Four changes:
- x86: work around two nasty cases where a benign exception occurs
while another is being delivered. The endless stream of exceptions
causes an infinite loop in the processor, which not even NMIs or
SMIs can interrupt; in the virt case, there is no possibility to
exit to the host either.
- x86: support for Skylake per-guest TSC rate. Long supported by
AMD, the patches mostly move things from there to common
arch/x86/kvm/ code.
- generic: remove local_irq_save/restore from the guest entry and
exit paths when context tracking is enabled. The patches are a few
months old, but we discussed them again at kernel summit. Andy
will pick up from here and, in 4.5, try to remove it from the user
entry/exit paths.

Building dwmac-ipq806x on a 64-bit architecture produces a harmless
warning from gcc:
stmmac/dwmac-ipq806x.c: In function 'ipq806x_gmac_probe':
include/linux/bitops.h:6:19: warning: overflow in implicit constant conversion [-Woverflow]
val = QSGMII_PHY_CDR_EN |
stmmac/dwmac-ipq806x.c:333:8: note: in expansion of macro 'QSGMII_PHY_CDR_EN'
#define QSGMII_PHY_CDR_EN BIT(0)
#define BIT(nr) (1UL << (nr))
This is a result of the type conversion rules in C, when we take the
logical OR of multiple different types. In particular, we have
and unsigned long
QSGMII_PHY_CDR_EN == BIT(0) == (1ul << 0) == 0x0000000000000001ul
and a signed int
0xC << QSGMII_PHY_TX_DRV_AMP_OFFSET == 0xc0000000
which together gives a signed long value
0xffffffffc0000001l
and when this is passed into a function that takes an unsigned int type,
gcc warns about the signed overflow and the loss of the upper 32-bits that
are all ones.
This patch adds 'ul' type modifiers to the literal numbers passed in
here, so now the expression remains an 'unsigned long' with the upper
bits all zero, and that avoids the signed overflow and the warning.

There are several sound drivers that 'select ZONE_DMA'. This is
backwards as ZONE_DMA is an architecture capability exported to drivers.
Switch the polarity of the dependency to disable these drivers when the
architecture does not support ZONE_DMA. This was discovered in the
context of testing/enabling devm_memremap_pages() which depends on
ZONE_DEVICE. ZONE_DEVICE in turn depends on !ZONE_DMA.
