Update get_swap_range_of_type for vanilla changes.

Update our mass-allocation function to match changes in vanilla. This
addresses a freeze on SSD devices caused by the new SSD specific code
getting in an infinite loop because it looks for newly added stats to
be updated.

Don't try to thaw processes when we haven't frozen them

The thaw_processes function now checks that the caller was
the same cpu that froze processes, by looking for PF_SUSPEND_TASK
flag. If this isn't set, it triggers a WARN_ON. To avoid this,
add a check that PF_SUSPEND_TASK is set before calling the function.

ALSA: hda - Fix silent output on ASUS W7J laptop

commit 6ddf0fd1c462a418a3cbb8b0653820dc48ffbd98 upstream.

The recent kernels got regressions on ASUS W7J with ALC660 codec where
no sound comes out.  After a long debugging session, we found out that
setting the pin control on the unused NID 0x10 is mandatory for the
outputs.  And, it was found out that another magic of NID 0x0f that is
required for other ASUS laptops isn't needed on this machine.

ASUS Z35HL laptop also needs the very same fix as the previous one
that was applied to ASUS W7J.

ALSA: hda - Use always amps for auto-mute on AD1986A codec

commit b3bd4fc3822a6b5883eaa556822487d87752d443 upstream.

It seems that AD1986A cannot manage the dynamic pin on/off for
auto-muting, but rather gets confused.  Since each output has own amp,
let's use it instead.

ALSA: hda - Fix headset mic input after muted internal mic (Dell/Realtek)

commit d59915d0655c5864b514f21daaeac98c047875dc upstream.

By trial and error, I found this patch could work around an issue
where the headset mic would stop working if you switch between the
internal mic and the headset mic, and the internal mic was muted.

It still takes a second or two before the headset mic actually starts
working, but still better than nothing.

Information update from Kailang:
  The verb was ADC digital mute(bit 6 default 1).
  Switch internal mic and headset mic will run alc_headset_mode_default.
  The coef index 0x11 will set to 0x0041.
  Because headset mode was fixed type. It doesn't need to run
  alc_determine_headset_type.
  So, the value still keep 0x0041. ADC was muted.

ALSA: hda - Fix bad EAPD setup for HP machines with AD1984A

commit 1cd9b2f78bf29d5282e02b32f9b3ecebc5842a7c upstream.

It seems that EAPD on NID 0x16 is the only control over all outputs on
HP machines with AD1984A while turning EAPD on NID 0x12 breaks the
output.  Thus we need to avoid fiddling EAPD on NID.  As a quick
workaround, just set own_eapd_ctrl flag for the wrong EAPD, then
implement finer EAPD controls.

crypto: s390 - Fix aes-xts parameter corruption

commit 9dda2769af4f3f3093434648c409bb351120d9e8 upstream.

Some s390 crypto algorithms incorrectly use the crypto_tfm structure to
store private data. As the tfm can be shared among multiple threads, this
can result in data corruption.

This patch fixes aes-xts by moving the xts and pcc parameter blocks from
the tfm onto the stack (48 + 96 bytes).

crypto: scatterwalk - Set the chain pointer indication bit

commit 41da8b5adba77e22584f8b45f9641504fa885308 upstream.

The scatterwalk_crypto_chain function invokes the scatterwalk_sg_chain
function to chain two scatterlists, but the chain pointer indication
bit is not set.  When the resulting scatterlist is used, for example,
by sg_nents to count the number of scatterlist entries, a segfault occurs
because sg_nents does not follow the chain pointer to the chained scatterlist.

Update scatterwalk_sg_chain to set the chain pointer indication bit as is
done by the sg_chain function.

crypto: ccm - Fix handling of zero plaintext when computing mac

commit 5638cabf3e4883f38dfb246c30980cebf694fbda upstream.

There are cases when cryptlen can be zero in crypto_ccm_auth():
-encryptiom: input scatterlist length is zero (no plaintext)
-decryption: input scatterlist contains only the mac
plus the condition of having different source and destination buffers
(or else scatterlist length = max(plaintext_len, ciphertext_len)).

These are not handled correctly, leading to crashes like:

When performing an asynchronous ablkcipher operation the authenc

the proper IV.

The callback routine, crypto_authenc_encrypt_done, is updated to use
the same method of calculating the address of the IV as is done in
crypto_authenc_encrypt function which sets up the callback.

which tears down the mappings.  Fix this.
