      x86/xen: Fix boot loader version reported for PVH guests · ed2df668
      Juergen Gross authored 
      commit 357d291c upstream.

The boot loader version reported via sysfs is wrong in case of the
kernel being booted via the Xen PVH boot entry. it should be 2.12
(0x020c), but it is reported to be 2.18 (0x0212).

As the current way to set the version is error prone use the more
readable variant (2 << 8) | 12.

      x86/speculation: Enable cross-hyperthread spectre v2 STIBP mitigation · 8a13906a
      Jiri Kosina authored 
      commit 53c613fe upstream.

STIBP is a feature provided by certain Intel ucodes / CPUs. This feature
(once enabled) prevents cross-hyperthread control of decisions made by
indirect branch predictors.

Enable this feature if

- the CPU is vulnerable to spectre v2
- the CPU supports SMT and has SMT siblings online
- spectre_v2 mitigation autoselection is enabled (default)

After some previous discussion, this leaves STIBP on all the time, as wrmsr
on crossing kernel boundary is a no-no. This could perhaps later be a bit
more optimized (like disabling it in NOHZ, experiment with disabling it in
idle, etc) if needed.

Note that the synchronization of the mask manipulation via newly added
spec_ctrl_mutex is currently not strictly needed, as the only updater is
already being serialized by cpu_add_remove_lock, but let's make this a
little bit more future-proof.

      ALSA: ca0106: Disable IZD on SB0570 DAC to fix audio pops · a436f6b2
      Alex Stanoev authored 
      commit ac237c28 upstream.

The Creative Audigy SE (SB0570) card currently exhibits an audible pop
whenever playback is stopped or resumed, or during silent periods of an
audio stream. Initialise the IZD bit to the 0 to eliminate these pops.

The Infinite Zero Detection (IZD) feature on the DAC causes the output
to be shunted to Vcap after 2048 samples of silence. This discharges the
AC coupling capacitor through the output and causes the aforementioned
pop/click noise.

The behaviour of the IZD bit is described on page 15 of the WM8768GEDS
datasheet: "With IZD=1, applying MUTE for 1024 consecutive input samples
will cause all outputs to be connected directly to VCAP. This also
happens if 2048 consecutive zero input samples are applied to all 6
channels, and IZD=0. It will be removed as soon as any channel receives
a non-zero input". I believe the second sentence might be referring to
IZD=1 instead of IZD=0 given the observed behaviour of the card.

This change should make the DAC initialisation consistent with
Creative's Windows driver, as this popping persists when initialising
the card in Linux and soft rebooting into Windows, but is not present on
a cold boot to Windows.

      parisc: Fix exported address of os_hpmc handler · d665f97f
      Helge Deller authored 
      commit 99a3ae51 upstream.

In the C-code we need to put the physical address of the hpmc handler in
the interrupt vector table (IVA) in order to get HPMCs working.  Since
on parisc64 function pointers are indirect (in fact they are function
descriptors) we instead export the address as variable and not as
function.

This reverts a small part of commit f39cce65 ("parisc: Add
cfi_startproc and cfi_endproc to assembly code").

      parisc: Fix map_pages() to not overwrite existing pte entries · e5475f5f
      Helge Deller authored 
      commit 3c229b3f upstream.

Fix a long-existing small nasty bug in the map_pages() implementation which
leads to overwriting already written pte entries with zero, *if* map_pages() is
called a second time with an end address which isn't aligned on a pmd boundry.
This happens for example if we want to remap only the text segment read/write
in order to run alternative patching on the code. Exiting the loop when we
reach the end address fixes this.

      parisc: Fix address in HPMC IVA · 472e3000
      John David Anglin authored 
      commit 1138b671 upstream.

Helge noticed that the address of the os_hpmc handler was not being
correctly calculated in the hpmc macro.  As a result, PDCE_CHECK would
fail to call os_hpmc:

The address problem can be seen by dumping the fault vector:

0000000040159000 <fault_vector_20>:
    40159000:   63 6f 77 73     stb r15,-2447(dp)

        ...

    40159028:   34 63 00 00     ldo 0(r3),r3
    4015902c:   e8 60 c0 02     bv,n r0(r3)
    40159030:   08 00 02 40     nop

    40159038:   c0 00 70 00     bb,*< r0,sar,40159840 <fault_vector_20+0x840>
    4015903c:   00 00 00 00     break 0,0

Location 40159038 should contain the physical address of os_hpmc:

000000004015d000 <os_hpmc>:
    4015d000:   08 1a 02 43     copy r26,r3
    4015d004:   01 c0 08 a4     mfctl iva,r4
    4015d008:   48 85 00 68     ldw 34(r4),r5

This patch moves the address setup into initialize_ivt to resolve the
above problem.  I tested the change by dumping the HPMC entry after setup:

0000000040209020:  8000240
0000000040209024: 206a2004

      pcmcia: Implement CLKRUN protocol disabling for Ricoh bridges · e3e48da8
      Maciej S. Szmigiero authored 
      commit 95691e3e upstream.

Currently, "disable_clkrun" yenta_socket module parameter is only
implemented for TI CardBus bridges.
Add also an implementation for Ricoh bridges that have the necessary
setting documented in publicly available datasheets.

Tested on a RL5C476II with a Sunrich C-160 CardBus NIC that doesn't work
correctly unless the CLKRUN protocol is disabled.

Let's also make it clear in its description that the "disable_clkrun"
module parameter only works on these two previously mentioned brands of
CardBus bridges.

      cpufreq: conservative: Take limits changes into account properly · f721267b
      Rafael J. Wysocki authored 
      commit da5e79bc upstream.

If the policy limits change between invocations of cs_dbs_update(),
the requested frequency value stored in dbs_info may not be updated
and the function may use a stale value of it next time.  Moreover, if
idle periods are takem into account by cs_dbs_update(), the requested
frequency value stored in dbs_info may be below the min policy limit,
which is incorrect.

To fix these problems, always update the requested frequency value
in dbs_info along with the local copy of it when the previous
requested frequency is beyond the policy limits and avoid decreasing
the requested frequency below the min policy limit when taking
idle periods into account.

Fixes: abb66279 (cpufreq: conservative: Fix next frequency selection)
Fixes: 00bfe058 (cpufreq: conservative: Decrease frequency faster for deferred updates)

      commit 92e2921f upstream.

When an invalid mount option is passed to jffs2, jffs2_parse_options()
will fail and jffs2_sb_info will be freed, but then jffs2_sb_info will
be used (use-after-free) and freeed (double-free) in jffs2_kill_sb().

Fix it by removing the buggy invocation of kfree() when getting invalid
mount options.

      hwmon: (pmbus) Fix page count auto-detection. · 0be4ef12
      Dmitry Bazhenov authored 
      commit e7c6a556 upstream.

Devices with compatible="pmbus" field have zero initial page count,
and pmbus_clear_faults() being called before the page count auto-
detection does not actually clear faults because it depends on the
page count. Non-cleared faults in its turn may fail the subsequent
page count auto-detection.

This patch fixes this problem by calling pmbus_clear_fault_page()
for currently set page and calling pmbus_clear_faults() after the
page count was detected.

      bcache: fix miss key refill->end in writeback · dcd048d6
      Tang Junhui authored 
      commit 2d6cb6ed upstream.

refill->end record the last key of writeback, for example, at the first
time, keys (1,128K) to (1,1024K) are flush to the backend device, but
the end key (1,1024K) is not included, since the bellow code:
	if (bkey_cmp(k, refill->end) >= 0) {
		ret = MAP_DONE;
		goto out;
	}
And in the next time when we refill writeback keybuf again, we searched
key start from (1,1024K), and got a key bigger than it, so the key
(1,1024K) missed.
This patch modify the above code, and let the end key to be included to
the writeback key buffer.

      bcache: trace missed reading by cache_missed · 82239bda
      Tang Junhui authored 
      commit 502b2915 upstream.

Missed reading IOs are identified by s->cache_missed, not the
s->cache_miss, so in trace_bcache_read() using trace_bcache_read
to identify whether the IO is missed or not.

      spi: bcm-qspi: switch back to reading flash using smaller chunks · 615bda31
      Rafał Miłecki authored 
      commit 940ec770 upstream.

Fixing/optimizing bcm_qspi_bspi_read() performance introduced two
changes:
1) It added a loop to read all requested data using multiple BSPI ops.
2) It bumped max size of a single BSPI block request from 256 to 512 B.

The later change resulted in occasional BSPI timeouts causing a
regression.

For some unknown reason hardware doesn't always handle reads as expected
when using 512 B chunks. In such cases it may happen that BSPI returns
amount of requested bytes without the last 1-3 ones. It provides the
remaining bytes later but doesn't raise an interrupt until another LR
start.

Switching back to 256 B reads fixes that problem and regression.

      mtd: spi-nor: fsl-quadspi: fix read error for flash size larger than 16MB · 31354285
      Liu Xiang authored 
      commit 41fe2429 upstream.

If the size of spi-nor flash is larger than 16MB, the read_opcode
is set to SPINOR_OP_READ_1_1_4_4B, and fsl_qspi_get_seqid() will
return -EINVAL when cmd is SPINOR_OP_READ_1_1_4_4B. This can
cause read operation fail.
