      ALSA: hda - Add mic quirk for the Lenovo G50-30 (17aa:3905) · e0404d81
      Jeremy Cline authored 
      commit e7bb6ad5 upstream.

The Lenovo G50-30, like other G50 models, has a Conexant codec that
requires a quirk for its inverted stereo dmic.

      ALSA: hda/realtek - Fix the problem of the front MIC on the Lenovo M715 · 7b50b3d7
      Hui Wang authored 
      commit d06fb562 upstream.

The front MIC on the Lenovo M715 can't record sound, after applying
the ALC294_FIXUP_LENOVO_MIC_LOCATION, the problem is fixed. So add
the pin configuration of this machine to the pin quirk table.

      ALSA: hda - Fix headphone pin config for ASUS G751 · 2ad912e2
      Takashi Iwai authored 
      commit 5b7c5e1f upstream.

BIOS on ASUS G751 doesn't seem to map the headphone pin (NID 0x16)
correctly.  Add a quirk to address it, as well as chaining to the
previous fix for the microphone.

      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)

    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

      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.

      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.

      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.

Fixes: e46ecda7 ("mtd: spi-nor: Add Freescale QuadSPI driver")
