#1184520 — [PATCH 3.16.y-ckt 142/185] ACPICA: Tables: Enable default 64-bit FADT addresses favor

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lv Zheng <lv.zheng@intel.com>

commit 0ea61381788a37d864f9841b0fe97d40f7058f3b upstream.

ACPICA commit 4da56eeae0749dfe8491285c1e1fad48f6efafd8

The following commit temporarily disables correct 64-bit FADT addresses
favor during the period the root cause of the bug is not fixed:
 Commit: 85dbd5801f62b66e2aa7826aaefcaebead44c8a6
 ACPICA: Tables: Restore old behavor to favor 32-bit FADT addresses.

With enough protections, this patch re-enables 64-bit FADT addresses by
default. If regressions are reported against such change, this patch should
be bisected and reverted.
Note that 64-bit FACS favor and 64-bit firmware waking vector favor are
excluded by this commit in order not to break OSPMs. Lv Zheng.

#1184524 — [PATCH 3.16.y-ckt 127/185] rbd: use GFP_NOIO in rbd_obj_request_create()

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ilya Dryomov <idryomov@gmail.com>

commit 5a60e87603c4c533492c515b7f62578189b03c9c upstream.

rbd_obj_request_create() is called on the main I/O path, so we need to
use GFP_NOIO to make sure allocation doesn't blow back on us.  Not all
callers need this, but I'm still hardcoding the flag inside rather than
making it a parameter because a) this is going to stable, and b) those
callers shouldn't really use rbd_obj_request_create() and will be fixed
in the future.

More memory allocation fixes will follow.

#1184525 — [PATCH 3.16.y-ckt 137/185] mnt: Update fs_fully_visible to test for permanently empty directories

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Eric W. Biederman" <ebiederm@xmission.com>

commit 7236c85e1be51a9e25ba0f6e087a66ca89605a49 upstream.

fs_fully_visible attempts to make fresh mounts of proc and sysfs give
the mounter no more access to proc and sysfs than if they could have
by creating a bind mount.  One aspect of proc and sysfs that makes
this particularly tricky is that there are other filesystems that
typically mount on top of proc and sysfs.  As those filesystems are
mounted on empty directories in practice it is safe to ignore them.
However testing to ensure filesystems are mounted on empty directories
has not been something the in kernel data structures have supported so
the current test for an empty directory which checks to see
if nlink <= 2 is a bit lacking.

proc and sysfs have recently been modified to use the new empty_dir
infrastructure to create all of their dedicated mount points.  Instead
of testing for S_ISDIR(inode->i_mode) && i_nlink <= 2 to see if a
directory is empty, test for is_empty_dir_inode(inode).  That small
change guaranteess mounts found on proc and sysfs really are safe to
ignore, because the directories are not only empty but nothing can
ever be added to them.  This guarantees there is nothing to worry
about when mounting proc and sysfs.

#1184528 — [PATCH 3.16.y-ckt 153/185] HID: i2c-hid: fix harmless test_bit() issue

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@oracle.com>

commit c8fd51dc12c6e22bb97d5e273babcf339770aba5 upstream.

These defines are used like this:

	if (test_bit(I2C_HID_STARTED, &ihid->flags))

The intent was to use bits 0, 1, and 2 but because of the extra shifts
we're using bits 1, 2, and 4.  It's harmless becuase it's done
consistently but it's not the intent and static checkers will complain.

#1184531 — [PATCH 3.16.y-ckt 126/185] crush: fix a bug in tree bucket decode

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ilya Dryomov <idryomov@gmail.com>

commit 82cd003a77173c91b9acad8033fb7931dac8d751 upstream.

struct crush_bucket_tree::num_nodes is u8, so ceph_decode_8_safe()
should be used.  -Wconversion catches this, but I guess it went
unnoticed in all the noise it spews.  The actual problem (at least for
common crushmaps) isn't the u32 -> u8 truncation though - it's the
advancement by 4 bytes instead of 1 in the crushmap buffer.

#1184532 — [PATCH 3.16.y-ckt 132/185] fs: Add helper functions for permanently empty directories.

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Eric W. Biederman" <ebiederm@xmission.com>

commit fbabfd0f4ee2e8847bf56edf481249ad1bb8c44d upstream.

To ensure it is safe to mount proc and sysfs I need to check if
filesystems that are mounted on top of them are mounted on truly empty
directories.  Given that some directories can gain entries over time,
knowing that a directory is empty right now is insufficient.

Therefore add supporting infrastructure for permantently empty
directories that proc and sysfs can use when they create mount points
for filesystems and fs_fully_visible can use to test for permanently
empty directories to ensure that nothing will be gained by mounting a
fresh copy of proc or sysfs.

#1184533 — [PATCH 3.16.y-ckt 143/185] KVM: x86: make vapics_in_nmi_mode atomic

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: =?UTF-8?q?Radim=20Kr=C4=8Dm=C3=A1=C5=99?= <rkrcmar@redhat.com>

commit 42720138b06301cc8a7ee8a495a6d021c4b6a9bc upstream.

Writes were a bit racy, but hard to turn into a bug at the same time.
(Particularly because modern Linux doesn't use this feature anymore.)

[Actually the next patch makes it much, much easier to trigger the race
 so I'm including this one for stable@ as well. - Paolo]

#1184536 — [PATCH 3.16.y-ckt 122/185] drm/radeon: SDMA fix hibernation (CI GPU family).

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: =?UTF-8?q?J=C3=A9r=C3=B4me=20Glisse?= <jglisse@redhat.com>

commit 2ba8d1bb8f6b589037f7db1f01144fc80750e8f7 upstream.

In order for hibernation to reliably work we need to properly turn
off the SDMA block, sadly after numerous attemps i haven't not found
proper sequence for clean and full shutdown. So simply reset both
SDMA block, this makes hibernation works reliably on sea island GPU
family (CI)

Hibernation and suspend to ram were tested (several times) on :
Bonaire
Hawaii
Mullins
Kaveri
Kabini

#1184537 — [PATCH 3.16.y-ckt 139/185] hwmon: (mcp3021) Fix broken output scaling

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Stevens, Nick" <Nick.Stevens@digi.com>

commit 347d7e45bd09ce09cbc30d5cea9de377eb22f55c upstream.

The mcp3021 scaling code is dividing the VDD (full-scale) value in
millivolts by the A2D resolution to obtain the scaling factor. When VDD
is 3300mV (the standard value) and the resolution is 12-bit (4096
divisions), the result is a scale factor of 3300/4096, which is always
one.  Effectively, the raw A2D reading is always being returned because
no scaling is applied.

This patch fixes the issue and simplifies the register-to-volts
calculation, removing the unneeded "output_scale" struct member.

From: Stefan Wahren <stefan.wahren@i2se.com>

commit 7cb81136d2efe0f5ed9d965857f4756a15e6c338 upstream.

key/value pairs in a JSON object must be separated by a comma.
After adding the properties "accuracy" and "phase" the JSON output
of /sys/kernel/debug/clk/clk_dump is invalid.

So add the missing commas to fix it.

#1184539 — [PATCH 3.16.y-ckt 125/185] net: mvneta: disable IP checksum with jumbo frames for Armada 370

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Simon Guinot <simon.guinot@sequanux.org>

commit b65657fc240ae6c1d2a1e62db9a0e61ac9631d7a upstream.

The Ethernet controller found in the Armada 370, 380 and 385 SoCs don't
support TCP/IP checksumming with frame sizes larger than 1600 bytes.

This patch fixes the issue by disabling the features NETIF_F_IP_CSUM and
NETIF_F_TSO for the Armada 370 and compatibles SoCs when the MTU is set
to a value greater than 1600 bytes.

#1184540 — [PATCH 3.16.y-ckt 136/185] sysfs: Add support for permanently empty directories to serve as mount points.

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Eric W. Biederman" <ebiederm@xmission.com>

commit 87d2846fcf88113fae2341da1ca9a71f0d916f2c upstream.

Add two functions sysfs_create_mount_point and
sysfs_remove_mount_point that hang a permanently empty directory off
of a kobject or remove a permanently emptpy directory hanging from a
kobject.  Export these new functions so modular filesystems can use
them.

#1184541 — [PATCH 3.16.y-ckt 131/185] VFS: Introduce inode-getting helpers for layered/unioned fs environments

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Howells <dhowells@redhat.com>

commit 155e35d4daa804582f75acaa2c74ec797a89c615 upstream.

Introduce some function for getting the inode (and also the dentry) in an
environment where layered/unioned filesystems are in operation.

The problem is that we have places where we need *both* the union dentry and
the lower source or workspace inode or dentry available, but we can only have
a handle on one of them.  Therefore we need to derive the handle to the other
from that.

The idea is to introduce an extra field in struct dentry that allows the union
dentry to refer to and pin the lower dentry.

#1184542 — [PATCH 3.16.y-ckt 095/185] arm64: vdso: work-around broken ELF toolchains in Makefile

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Will Deacon <will.deacon@arm.com>

commit 6f1a6ae87c0c60d7c462ef8fd071f291aa7a9abb upstream.

When building the kernel with a bare-metal (ELF) toolchain, the -shared
option may not be passed down to collect2, resulting in silent corruption
of the vDSO image (in particular, the DYNAMIC section is omitted).

The effect of this corruption is that the dynamic linker fails to find
the vDSO symbols and libc is instead used for the syscalls that we
intended to optimise (e.g. gettimeofday). Functionally, there is no
issue as the sigreturn trampoline is still intact and located by the
kernel.

This patch fixes the problem by explicitly passing -shared to the linker
when building the vDSO.

commit 7819717b11346b8a5420b223b46600e394049c66 upstream.

Acer Aspire V5 with ALC282 codec needs the similar quirk like Dell
laptops to support the headset mic.  The headset mic pin is 0x19 and
it's not exposed by BIOS, thus we need to fix the pincfg as well.

#1184545 — [PATCH 3.16.y-ckt 121/185] drm/radeon: compute ring fix hibernation (CI GPU family) v2.

3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: =?UTF-8?q?J=C3=A9r=C3=B4me=20Glisse?= <jglisse@redhat.com>

commit 161569deaa03cf3c00ed63352006193f250b0648 upstream.

In order for hibernation to reliably work we need to cleanup more
thoroughly the compute ring. Hibernation is different from suspend
resume as when we resume from hibernation the hardware is first
fully initialize by regular kernel then freeze callback happens
(which correspond to a suspend inside the radeon kernel driver)
and turn off each of the block. It turns out we were not cleanly
shutting down the compute ring. This patch fix that.

Hibernation and suspend to ram were tested (several times) on :
Bonaire
Hawaii
Mullins
Kaveri
Kabini

Changed since v1:
  - Factor the ring stop logic into a function taking ring as arg.
