Pull power management fixes from Rafael Wysocki:
"These address a corner case in the menu cpuidle governor and fix error
handling in the PM core's generic clock management code.
Specifics:
- Make the menu cpuidle governor avoid stopping the scheduler tick if
the predicted idle duration exceeds the tick period length, but the
selected idle state is shallow and deeper idle states with high
target residencies are available (Rafael Wysocki).
- Make the PM core's generic clock management code use a proper data
type for one variable to make error handling work (Dan Carpenter)"

The case addressed by commit 5ef499cd571c (cpuidle: menu: Handle
stopped tick more aggressively) in the stopped tick case is present
when the tick has not been stopped yet too. Namely, if only two CPU
idle states, shallow state A with target residency significantly
below the tick boundary and deep state B with target residency
significantly above it, are available and the predicted idle
duration is above the tick boundary, but below the target residency
of state B, state A will be selected and the CPU may spend indefinite
amount of time in it, which is not quite energy-efficient.
However, if the tick has not been stopped yet and the governor is
about to select a shallow idle state for the CPU even though the idle
duration predicted by it is above the tick boundary, it should be
fine to wake up the CPU early, so the tick can be retained then and
the governor will have a chance to select a deeper state when it runs
next time.
[Note that when this really happens, it will make the idle duration
predictor believe that the CPU might be idle longer than predicted,
which will make it more likely to predict longer idle durations going
forward, but that will also cause deeper idle states to be selected
going forward, on average, which is what's needed here.]

When a targetport is removed from the config, fcloop will avoid calling
the LS done() routine thinking the targetport is gone. This leaves the
initiator reset/reconnect hanging as it waits for a status on the
Create_Association LS for the reconnect.
Change the filter in the LS callback path. If tport null (set when
failed validation before "sending to remote port"), be sure to call
done. This was the main bug. But, continue the logic that only calls
done if tport was set but there is no remoteport (e.g. case where
remoteport has been removed, thus host doesn't expect a completion).

In many architectures loads may be reordered with older stores to
different locations. In the nvme driver the following two operations
could be reordered:
- Write shadow doorbell (dbbuf_db) into memory.
- Read EventIdx (dbbuf_ei) from memory.
This can result in a potential race condition between driver and VM host
processing requests (if given virtual NVMe controller has a support for
shadow doorbell). If that occurs, then the NVMe controller may decide to
wait for MMIO doorbell from guest operating system, and guest driver may
decide not to issue MMIO doorbell on any of subsequent commands.
This issue is purely timing-dependent one, so there is no easy way to
reproduce it. Currently the easiest known approach is to run "Oracle IO
Numbers" (orion) that is shipped with Oracle DB:
orion -run advanced -num_large 0 -size_small 8 -type rand -simulate \
concat -write 40 -duration 120 -matrix row -testname nvme_test
Where nvme_test is a .lun file that contains a list of NVMe block
devices to run test against. Limiting number of vCPUs assigned to given
VM instance seems to increase chances for this bug to occur. On test
environment with VM that got 4 NVMe drives and 1 vCPU assigned the
virtual NVMe controller hang could be observed within 10-20 minutes.
That correspond to about 400-500k IO operations processed (or about
100GB of IO read/writes).
Orion tool was used as a validation and set to run in a loop for 36
hours (equivalent of pushing 550M IO operations). No issues were
observed. That suggest that the patch fixes the issue.

The DMA is broken on this specific device for some unknown
reason (probably badly designed or plain broken interface
electronics) and will only work with PIO. Other users of
the same hardware does not have this problem.
Add a specific quirk so that this Gemini device gets
DMA turned off. Also fix up some code around passing the
port information around in probe while we're at it.

Persistent grants are allocated until a threshold per ring is being
reached. Those grants won't be freed until the ring is being destroyed
meaning there will be resources kept busy which might no longer be
used.
Instead of freeing only persistent grants until the threshold is
reached add a timestamp and remove all persistent grants not having
been in use for a minute.

Commit 49aa76b16676 ("mtd: rawnand: do not execute nand_scan_ident()
if maxchips is zero") gave a new meaning for calling nand_scan_ident()
with maxchips=0.
It is a special usage for some drivers such as docg4, but actually
the Denali driver may pass maxchips=0 to nand_scan() when the driver
is enabled but no NAND chip is found on the board for some reasons.
If nand_scan_with_ids() is called with maxchips=0, nand_scan_ident()
is skipped, then nand_set_defaults() is skipped as well. Thus, the
driver must set chip->controller beforehand. Otherwise, nand_attach()
causes NULL pointer dereference.
In fact, the Denali controller knows the number of connected chips
before calling nand_scan_ident(); if DEVICE_RESET fails, there is no
chip in that chip select. Then, denali_reset_banks() sets the maxchips
to the number of detected chips. If no chip is found, maxchips is zero.
In this case, there is no point for calling nand_scan() because we know
it will fail for sure. Let's make the probe function fail immediately.

If gcc (e.g. 4.1.2) decides not to inline init_mtd_structs() and
read_id_reg(), this will cause section mismatches, and crashes:
WARNING: drivers/mtd/nand/raw/docg4.o(.text+0xc10): Section mismatch in reference from the function docg4_attach_chip() to the function .init.text:init_mtd_structs()
The function docg4_attach_chip() references
the function __init init_mtd_structs().
This is often because docg4_attach_chip lacks a __init
annotation or the annotation of init_mtd_structs is wrong.
WARNING: drivers/mtd/nand/raw/docg4.o(.text+0xc3e): Section mismatch in reference from the function docg4_attach_chip() to the function .init.text:read_id_reg()
The function docg4_attach_chip() references
the function __init read_id_reg().
This is often because docg4_attach_chip lacks a __init
annotation or the annotation of read_id_reg is wrong.
Fix this by dropping the now incorrect __init annotations from
init_mtd_structs() and read_id_reg().

I have encountered an interrupt storm during the eMMC chip probing (and
the chip finally didn't get detected). It turned out that U-Boot left
the SDHI DMA interrupts enabled while the Linux driver didn't use those.
Masking those interrupts in renesas_sdhi_internal_dmac_request_dma() gets
rid of both issues...

The mmc block driver does not support parallel dispatch of requests. In
normal circumstances, all requests are anyway funneled through a single
work item, so parallel dispatch never happens. However it can happen if
there is no elevator.
Fix that by detecting if a dispatch is in progress and returning busy
(BLK_STS_RESOURCE) in that case

The conversion to sg_copy_{from,to}_buffer has been done in the wrong
way. sg_copy_to_buffer is a copy from an SG list to a linear buffer so
it can't replace memcpy(dest, host->virt_base, data->sg->length) where
dest is the virtual address of the SG. Same for sg_copy_from_buffer
but in the opposite way.

val can be indirectly controlled by user-space, hence leading to
a potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
vers/hwmon/nct6775.c:2698 store_pwm_weight_temp_sel() warn: potential
spectre issue 'data->temp_src' [r]
Fix this by sanitizing val before using it to index data->temp_src
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

The adt7475_update_device() function returns error pointers. The
problem is that in show_pwmfreq() we dereference it before the check.
And then in pwm_use_point2_pwm_at_crit_show() there isn't a check at
all. I don't know if it's required, but it silences a static checker
warning and it's doesn't hurt anything to check.

This patch fixes sleep-in-atomic bugs in AES-CBC and AES-XTS VMX
implementations. The problem is that the blkcipher_* functions should
not be called in atomic context.
The bugs can be reproduced via the AF_ALG interface by trying to
encrypt/decrypt sufficiently large buffers (at least 64 KiB) using the
VMX implementations of 'cbc(aes)' or 'xts(aes)'. Such operations then
trigger BUG in crypto_yield():
