#1369769 — [PATCH 3.19.y-ckt 091/170] s390/pci: enforce fmb page boundary rule

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Sebastian Ott <sebott@linux.vnet.ibm.com>

commit 80c544ded25ac14d7cc3e555abb8ed2c2da99b84 upstream.

The function measurement block must not cross a page boundary. Ensure
that by raising the alignment requirement to the smallest power of 2
larger than the size of the fmb.

#1369770 — [PATCH 3.19.y-ckt 115/170] rapidio/rionet: fix deadlock on SMP

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Aurelien Jacquiot <a-jacquiot@ti.com>

commit 36915976eca58f2eefa040ba8f9939672564df61 upstream.

Fix deadlocking during concurrent receive and transmit operations on SMP
platforms caused by the use of incorrect lock: on transmit 'tx_lock'
spinlock should be used instead of 'lock' which is used for receive
operation.

This fix is applicable to kernel versions starting from v2.15.

#1369771 — [PATCH 3.19.y-ckt 131/170] ethernet: micrel: fix some error codes

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

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

commit 3af0d554c1ce11e9d0953381ff566271f9ab81a9 upstream.

There were two issues here:
1) dma_mapping_error() return true/false but we want to return -ENOMEM
2) If dmaengine_prep_slave_sg() failed then "err" wasn't set but
   presumably that should be -ENOMEM as well.

I changed the success path to "return 0;" instead of "return ret;" for
clarity.

#1369773 — [PATCH 3.19.y-ckt 124/170] xen kconfig: don't "select INPUT_XEN_KBDDEV_FRONTEND"

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Arnd Bergmann <arnd@arndb.de>

commit 13aa38e291bdd4e4018f40dd2f75e464814dcbf3 upstream.

The Xen framebuffer driver selects the xen keyboard driver, so the latter
will be built-in if XEN_FBDEV_FRONTEND=y. However, when CONFIG_INPUT
is a loadable module, this configuration cannot work. On mainline kernels,
the symbol will be enabled but not used, while in combination with
a patch I have to detect such useless configurations, we get the
expected link failure:

drivers/input/built-in.o: In function `xenkbd_remove':
xen-kbdfront.c:(.text+0x2f0): undefined reference to `input_unregister_device'
xen-kbdfront.c:(.text+0x30e): undefined reference to `input_unregister_device'

This removes the extra "select", as it just causes more trouble than
it helps. In theory, some defconfig file might break if it has
XEN_FBDEV_FRONTEND in it but not INPUT_XEN_KBDDEV_FRONTEND. The Kconfig
fragment we ship in the kernel (kernel/configs/xen.config) however
already enables both, and anyone using an old .config file would
keep having both enabled.

#1369774 — [PATCH 3.19.y-ckt 086/170] xtensa: ISS: don't hang if stdin EOF is reached

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Max Filippov <jcmvbkbc@gmail.com>

commit 362014c8d9d51d504c167c44ac280169457732be upstream.

Simulator stdin may be connected to a file, when its end is reached
kernel hangs in infinite loop inside rs_poll, because simc_poll always
signals that descriptor 0 is readable and simc_read always returns 0.
Check simc_read return value and exit loop if it's not positive. Also
don't rewind polling timer if it's zero.

#1369775 — [PATCH 3.19.y-ckt 082/170] dm thin metadata: don't issue prefetches if a transaction abort has failed

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Joe Thornber <ejt@redhat.com>

commit 2eae9e4489b4cf83213fa3bd508b5afca3f01780 upstream.

If a transaction abort has failed then we can no longer use the metadata
device.  Typically this happens if the superblock is unreadable.

This fix addresses a crash seen during metadata device failure testing.

#1369777 — [PATCH 3.19.y-ckt 064/170] KVM: i8254: change PIT discard tick policy

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

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

commit 7dd0fdff145c5be7146d0ac06732ae3613412ac1 upstream.

Discard policy uses ack_notifiers to prevent injection of PIT interrupts
before EOI from the last one.

This patch changes the policy to always try to deliver the interrupt,
which makes a difference when its vector is in ISR.
Old implementation would drop the interrupt, but proposed one injects to
IRR, like real hardware would.

The old policy breaks legacy NMI watchdogs, where PIT is used through
virtual wire (LVT0): PIT never sends an interrupt before receiving EOI,
thus a guest deadlock with disabled interrupts will stop NMIs.

Note that NMI doesn't do EOI, so PIT also had to send a normal interrupt
through IOAPIC.  (KVM's PIT is deeply rotten and luckily not used much
in modern systems.)

Even though there is a chance of regressions, I think we can fix the
LVT0 NMI bug without introducing a new tick policy.

#1369778 — [PATCH 3.19.y-ckt 074/170] x86/PCI: Mark Broadwell-EP Home Agent & PCU as having non-compliant BARs

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

From: Bjorn Helgaas <bhelgaas@google.com>

commit b894157145e4ac7598d7062bc93320898a5e059e upstream.

The Home Agent and PCU PCI devices in Broadwell-EP have a non-BAR register
where a BAR should be.  We don't know what the side effects of sizing the
"BAR" would be, and we don't know what address space the "BAR" might appear
to describe.

Mark these devices as having non-compliant BARs so the PCI core doesn't
touch them.

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Mario Kleiner <mario.kleiner.de@gmail.com>

commit 459ee1c3fd097ab56ababd8ff4bb7ef6a792de33 upstream.

As observed on Apple iMac10,1, DCE-3.2, RV-730,
link rate of 2.7 Ghz is not selected, because
the args.v1.ucConfig flag setting for 2.7 Ghz
gets overwritten by a following assignment of
the transmitter to use.

Move link rate setup a few lines down to fix this.
In practice this didn't have any positive or
negative effect on display setup on the tested
iMac10,1 so i don't know if backporting to stable
makes sense or not.

From: Vinayak Menon <vinmenon@codeaurora.org>

commit e53b50c0cbe392c946807abf7d07615a3c588642 upstream.

early_init_dt_alloc_reserved_memory_arch passes end as 0 to
__memblock_alloc_base, when limits are not specified. But
__memblock_alloc_base takes end value of 0 as MEMBLOCK_ALLOC_ACCESSIBLE
and limits the end to memblock.current_limit. This results in regions
never being placed in HIGHMEM area, for e.g. CMA.
Let __memblock_alloc_base allocate from anywhere in memory if limits are
not specified.

#1369783 — [PATCH 3.19.y-ckt 092/170] md: multipath: don't hardcopy bio in .make_request path

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Ming Lei <ming.lei@canonical.com>

commit fafcde3ac1a418688a734365203a12483b83907a upstream.

Inside multipath_make_request(), multipath maps the incoming
bio into low level device's bio, but it is totally wrong to
copy the bio into mapped bio via '*mapped_bio = *bio'. For
example, .__bi_remaining is kept in the copy, especially if
the incoming bio is chained to via bio splitting, so .bi_end_io
can't be called for the mapped bio at all in the completing path
in this kind of situation.

This patch fixes the issue by using clone style.

#1369784 — [PATCH 3.19.y-ckt 063/170] usb: hub: fix a typo in hub_port_init() leading to wrong logic

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Oliver Neukum <oneukum@suse.com>

commit 0d5ce778c43bf888328231bcdce05d5c860655aa upstream.

A typo of j for i led to a logic bug. To rule out future
confusion, the variable names are made meaningful.

#1369786 — [PATCH 3.19.y-ckt 089/170] bus: imx-weim: Take the 'status' property value into account

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Fabio Estevam <fabio.estevam@nxp.com>

commit 33b96d2c9579213cf3f36d7b29841b1e464750c4 upstream.

Currently we have an incorrect behaviour when multiple devices
are present under the weim node. For example:

&weim {
	...
	status = "okay";

	sram@0,0 {
		...
        	status = "okay";
	};

	mram@0,0 {
		...
        	status = "disabled";
    	};
};

In this case only the 'sram' device should be probed and not 'mram'.

However what happens currently is that the status variable is ignored,
causing the 'sram' device to be disabled and 'mram' to be enabled.

Change the weim_parse_dt() function to use
for_each_available_child_of_node()so that the devices marked with
'status = disabled' are not probed.

#1369787 — [PATCH 3.19.y-ckt 052/170] watchdog: rc32434_wdt: fix ioctl error handling

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: "Michael S. Tsirkin" <mst@redhat.com>

commit 10e7ac22cdd4d211cef99afcb9371b70cb175be6 upstream.

Calling return copy_to_user(...) in an ioctl will not do the right thing
if there's a pagefault: copy_to_user returns the number of bytes not
copied in this case.

Fix up watchdog/rc32434_wdt to do
	return copy_to_user(...)) ?  -EFAULT : 0;

instead.

#1369788 — [PATCH 3.19.y-ckt 068/170] perf/core: Fix perf_sched_count derailment

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Alexander Shishkin <alexander.shishkin@linux.intel.com>

commit 927a5570855836e5d5859a80ce7e91e963545e8f upstream.

The error path in perf_event_open() is such that asking for a sampling
event on a PMU that doesn't generate interrupts will end up in dropping
the perf_sched_count even though it hasn't been incremented for this
event yet.

Given a sufficient amount of these calls, we'll end up disabling
scheduler's jump label even though we'd still have active events in the
system, thereby facilitating the arrival of the infernal regions upon us.

I'm fixing this by moving account_event() inside perf_event_alloc().
