If a process is interrupted while accessing the "gpu" debugfs file and
the drm device struct_mutex is contended, release() could return early
and fail to free related resources.
Note that the return value from release() is ignored.

Add a statx attribute bit STATX_ATTR_VERITY which will be set if the
file has fs-verity enabled. This is the statx() equivalent of
FS_VERITY_FL which is returned by FS_IOC_GETFLAGS.
This is useful because it allows applications to check whether a file is
a verity file without opening it. Opening a verity file can be
expensive because the fsverity_info is set up on open, which involves
parsing metadata and optionally verifying a cryptographic signature.
This is analogous to how various other bits are exposed through both
FS_IOC_GETFLAGS and statx(), e.g. the encrypt bit.

net: macb: convert to phylink
This series converts the MACB Ethernet driver to the Phylink framework.
The MAC configuration is moved to the Phylink ops and Phylink helpers
are now used in the ethtools functions. This helps to access the flow
control and pauseparam logic and this will be helpful in the future for
boards using this controller with SFP cages.
Since v2:
- Moved the Tx and Rx buffer initialization rework to its own patch.
Since v1:
- Stopped using state->link in mac_config and moved macb_set_tx_clk to
the link_up helper..
- Fixed the node given to phylink_of_phy_connect.
- Removed netif_carrier_off from macb_open.
- Fixed the macb_get_wol logic.
- Rewored macb_ioctl as suggested.
- Added a call to phylink_destroy in macb_remove.
- Fixed the suspend/resume case by calling phylink_start/stop in the
resume/suspend helpers. I had to take the rtnl lock to do this,
which might be something to discuss.

For cancellation, we need to ensure that the work item stays valid for
as long as ->cur_work is valid. Right now we can't safely dereference
the work item even under the wqe->lock, because while the ->cur_work
pointer will remain valid, the work could be completing and be freed
in parallel.
Only invoke ->get/put_work() on items we know that the caller queued
themselves. Add IO_WQ_WORK_INTERNAL for io-wq to use, which is needed
when we're queueing a flush item, for instance.

On a system without KVM_COMPAT, we prevent IOCTLs from being issued
by a compat task. Although this prevents most silly things from
happening, it can still confuse a 32bit userspace that is able
to open the kvm device (the qemu test suite seems to be pretty
mad with this behaviour).
Take a more radical approach and return a -ENODEV to the compat
task.

MMC IOCTLS with R1B responses may cause the card to enter the busy state,
which means it's not ready to receive a new request. To prevent new
requests from being sent to the card, use a CMD13 polling loop to verify
that the card returns to the transfer state, before completing the request.

A previous patch implemented an incomplete workaround of erratum
A-008171. The complete workaround is as below. This patch is to
implement the complete workaround which uses SW tuning if HW tuning
fails, and retries both HW/SW tuning once with reduced clock if
workaround fails. This is suggested by hardware team, and the patch
had been verified on LS1046A eSDHC + Phison 32G eMMC which could
trigger the erratum.
Workaround:
/* For T1040, T2080, LS1021A, T1023 Rev 1: */
1. Program TBPTR[TB_WNDW_END_PTR] = 3*DIV_RATIO.
2. Program TBPTR[TB_WNDW_START_PTR] = 5*DIV_RATIO.
3. Program the software tuning mode by setting TBCTL[TB_MODE] = 2'h3.
4. Set SYSCTL2[EXTN] and SYSCTL2[SAMPCLKSEL].
5. Issue SEND_TUNING_BLK Command (CMD19 for SD, CMD21 for MMC).
6. Wait for IRQSTAT[BRR], buffer read ready, to be set.
7. Clear IRQSTAT[BRR].
8. Check SYSCTL2[EXTN] to be cleared.
9. Check SYSCTL2[SAMPCLKSEL], Sampling Clock Select. It's set value
indicate tuning procedure success, and clear indicate failure.
In case of tuning failure, fixed sampling scheme could be used by
clearing TBCTL[TB_EN].
/* For LS1080A Rev 1, LS2088A Rev 1.0, LA1575A Rev 1.0: */
1. Read the TBCTL[31:0] register. Write TBCTL[11:8]=4'h8 and wait for
1ms.
2. Read the TBCTL[31:0] register and rewrite again. Wait for 1ms second.
3. Read the TBSTAT[31:0] register twice.
3.1 Reset data lines by setting ESDHCCTL[RSTD] bit.
3.2 Check ESDHCCTL[RSTD] bit.
3.3 If ESDHCCTL[RSTD] is 0, go to step 3.4 else go to step 3.2.
3.4 Write 32'hFFFF_FFFF to IRQSTAT register.
4. if TBSTAT[15:8]-TBSTAT[7:0] > 4*DIV_RATIO or TBSTAT[7:0]-TBSTAT[15:8]
> 4*DIV_RATIO , then program TBPTR[TB_WNDW_END_PTR] = 4*DIV_RATIO and
program TBPTR[TB_WNDW_START_PTR] = 8*DIV_RATIO.
/* For LS1012A Rev1, LS1043A Rev 1.x, LS1046A 1.0: */
1. Read the TBCTL[0:31] register. Write TBCTL[20:23]=4'h8 and wait for
1ms.
2. Read the TBCTL[0:31] register and rewrite again. Wait for 1ms second.
3. Read the TBSTAT[0:31] register twice.
3.1 Reset data lines by setting ESDHCCTL[RSTD] bit.
3.2 Check ESDHCCTL[RSTD] bit.
3.3 If ESDHCCTL[RSTD] is 0, go to step 3.4 else go to step 3.2.
3.4 Write 32'hFFFF_FFFF to IRQSTAT register.
4. if TBSTAT[16:23]-TBSTAT[24:31] > 4*DIV_RATIO or TBSTAT[24:31]-
TBSTAT[16:23] > 4* DIV_RATIO , then program TBPTR[TB_WNDW_END_PTR] =
4*DIV_RATIO and program TBPTR[TB_WNDW_START_PTR] = 8*DIV_RATIO.
/* For LS1080A Rev 1, LS2088A Rev 1.0, LA1575A Rev 1.0 LS1012A Rev1,
* LS1043A Rev 1.x, LS1046A 1.0:
*/
5. else program TBPTR[TB_WNDW_END_PTR] = 3*DIV_RATIO and program
TBPTR[TB_WNDW_START_PTR] = 5*DIV_RATIO.
6. Program the software tuning mode by setting TBCTL[TB_MODE] = 2'h3.
7. Set SYSCTL2[EXTN], wait 1us and SYSCTL2[SAMPCLKSEL].
8. Issue SEND_TUNING_BLK Command (CMD19 for SD, CMD21 for MMC).
9. Wait for IRQSTAT[BRR], buffer read ready, to be set.
10. Clear IRQSTAT[BRR].
11. Check SYSCTL2[EXTN] to be cleared.

Add a property to keep the analog calibration cell powered.
This feature is specific to the Microchip SDHCI IP and outside
of the standard SDHCI register map.
By always keeping it on, after a full reset sequence, we make sure
that this feature is activated and not disabled.
We expose a hardware property to the DT as this feature can be used
to adapt SDHCI behavior vs. how the SDCAL SoC pin is connected
on the board.
Note that managing properly this property would reduce
power consumption on some SAMA5D2 SiP revisions.

This optional property describes how the SoC SDCAL pin is connected.
It could be handled at SiP, SoM or board level.
This property read by at91 sdhci driver will allow to put in place a
