During suspend CPU context may be lost in both non-secure and secure CPU
states. The kernel can handle saving and restoring the non-secure context
but must call into the secure side to allow it to save any context it may
lose. Add these calls here.
Note that on systems with OP-TEE available the suspend call is issued to
OP-TEE using the ARM SMCCC, but the resume call is always issued to the
ROM. This is because on waking from suspend the ROM is restored as the
secure monitor. It is this resume call that instructs the ROM to restore
OP-TEE, all subsequent calls will be handled by OP-TEE and should use the
ARM SMCCC.

ARM: tegra: Enable PLLP bypass during Tegra124 LP1
For a little over a year, U-Boot has configured the flow controller to
perform automatic RAM re-repair on off->on power transitions of the CPU
rail[1]. This is mandatory for correct operation of Tegra124. However,
RAM re-repair relies on certain clocks, which the kernel must enable and
leave running. PLLP is one of those clocks. This clock is shut down
during LP1 in order to save power. Enable bypass (which I believe routes
osc_div_clk, essentially the crystal clock, to the PLL output) so that
this clock signal toggles even though the PLL is not active. This is
required so that LP1 power mode (system suspend) operates correctly.
The bypass configuration must then be undone when resuming from LP1, so
that all peripheral clocks run at the expected rate. Without this, many
peripherals won't work correctly; for example, the UART baud rate would
be incorrect.
NVIDIA's downstream kernel code only does this if not compiled for
Tegra30, so the added code is made conditional upon the chip ID.
NVIDIA's downstream code makes this change conditional upon the active
CPU cluster. The upstream kernel currently doesn't support cluster
switching, so this patch doesn't test the active CPU cluster ID.

ARM: OMAP2+: use separate IOMMU pdata to fix DRA7 IPU1 boot
The IPU1 MMU has been using common IOMMU pdata quirks defined and
used by all IPU IOMMU devices on OMAP4 and beyond. Separate out the
pdata for IPU1 MMU with the additional .set_pwrdm_constraint ops
plugged in, so that the IPU1 power domain can be restricted to ON
state during the boot and active period of the IPU1 remote processor.
This eliminates the pre-conditions for the IPU1 boot issue as
described in commit afe518400bdb ("iommu/omap: fix boot issue on
remoteprocs with AMMU/Unicache").
NOTE:
1. RET is not a valid target power domain state on DRA7 platforms,
and IPU power domain is normally programmed for OFF. The IPU1
still fails to boot though, and an unclearable l3_noc error is
thrown currently on 4.14 kernel without this fix. This behavior
is slightly different from previous 4.9 LTS kernel.
2. The fix is currently applied only to IPU1 on DRA7xx SoC, as the
other affected processors on OMAP4/OMAP5/DRA7 are in domains
that are not entering RET. IPU2 on DRA7 is in CORE power domain
which is only programmed for ON power state. The fix can be easily
scaled if these domains do hit RET in the future.
3. The issue was not seen on current DRA7 platforms if any of the
DSP remote processors were booted and using one of the GPTimers
5, 6, 7 or 8 on previous 4.9 LTS kernel. This was due to the
errata fix for i874 implemented in commit 1cbabcb9807e ("ARM:
DRA7: clockdomain: Implement timer workaround for errata i874")
which keeps the IPU1 power domain from entering RET when the
timers are active. But the timer workaround did not make any
difference on 4.14 kernel, and an l3_noc error was seen still
without this fix.

ARM: OMAP2+: Add workaround for DRA7 DSP MStandby errata i879
Errata Title:
i879: DSP MStandby requires CD_EMU in SW_WKUP
Description:
The DSP requires the internal emulation clock to be actively toggling
in order to successfully enter a low power mode via execution of the
IDLE instruction and PRCM MStandby/Idle handshake. This assumes that
other prerequisites and software sequence are followed.
Workaround:
The emulation clock to the DSP is free-running anytime CCS is connected
via JTAG debugger to the DSP subsystem or when the CD_EMU clock domain
is set in SW_WKUP mode. The CD_EMU domain can be set in SW_WKUP mode
via the CM_EMU_CLKSTCTRL [1:0]CLKTRCTRL field.
Implementation:
This patch implements this workaround by denying the HW_AUTO mode
for the EMU clockdomain during the power-up of any DSP processor
and re-enabling the HW_AUTO mode during the shutdown of the last
DSP processor (actually done during the enabling and disabling of
the respective DSP MDMA MMUs). Reference counting has to be used to
manage the independent sequencing between the multiple DSP processors.
This switching is done at runtime rather than a static clockdomain
flags value to meet the target power domain state for the EMU power
domain during suspend.
Note that the DSP MStandby behavior is not consistent across all
boards prior to this fix. Please see commit 45f871eec6c0 ("ARM:

However, the check for that (of_have_populated_dt()) can change after

Some QPs (e.g. XRC QP) are not tracked in kernel, in this case they have

ksys_dup() is used only at one place in the kernel, namely to duplicate
fd 0 of /dev/console to stdout and stderr. The same functionality can be
achieved by using functions already available within the kernel namespace.

ARM: OMAP2+: am43xx: Add lcdc clockdomain
As described in AM437x TRM, spruhl7h, Revised January 2018, there is
an LCDC clockdomain present in the PER power domain. Although it is
entirely unused on AM437x, it should be defined along with the other
clockdomains so it can be shut off by Linux as there are no users.

block: fix NULL pointer dereference in account statistics with IDE
The IDE driver creates some passthru requests which never get
submitted to the block layer in such a way that blk_account_io_start()
gets called. However, the driver still calls __blk_mq_end_request() in
ide_end_rq() which will call blk_account_io_completion() which tries
to dereferences req->part which is never set. See ide_prep_sense() for
an example of where these requests come from.
To fix this, blk_account_io_completion() and blk_account_io_done()
should do nothing if req->part is not set.

drm/amdgpu: avoid using invalidate semaphore for picasso
It may cause timeout waiting for sem acquire in VM flush when using
invalidate semaphore for picasso. So it needs to avoid using invalidate
semaphore for piasso.
In prepare_namespace(), do_mount() can be used instead of ksys_mount()
as the first and third argument are const strings in the kernel, the
second and fourth argument are passed through anyway, and the fifth
argument is NULL.
In do_mount_root(), ksys_mount() is called with the first and third
argument being already kernelspace strings, which do not need to be
copied over from userspace to kernelspace (again). The second and
fourth arguments are passed through to do_mount() anyway. The fifth
argument, while already residing in kernelspace, needs to be put into
a page of its own. Then, do_mount() can be used instead of
ksys_mount().
Once this is done, there are no in-kernel users to ksys_mount() left,
which can therefore be removed.
All three calls to ksys_mount() in initrd-related kernel code can
be switched over to do_mount():
- the first and third arguments are const strings in the kernel,
and do not need to be copied over from userspace;
- the fifth argument is NULL, and therefore no page needs to be,
copied over from userspace;
- the second and fourth argument are passed through anyway.
In devtmpfs, do_mount() can be called directly instead of complex wrapping
by ksys_mount():
- the first and third arguments are const strings in the kernel,
and do not need to be copied over from userspace;
- the fifth argument is NULL, and therefore no page needs to be
copied over from userspace;
- the second and fourth argument are passed through anyway.

ARM: imx: Enable ARM_ERRATA_814220 for i.MX6UL and i.MX7D
ARM_ERRATA_814220 has below description:
The v7 ARM states that all cache and branch predictor maintenance
operations that do not specify an address execute, relative to
each other, in program order.
However, because of this erratum, an L2 set/way cache maintenance
operation can overtake an L1 set/way cache maintenance operation.
This ERRATA only affected the Cortex-A7 and present in r0p2, r0p3,
r0p4, r0p5.
i.MX6UL and i.MX7D have Cortex-A7 r0p5 inside, need to enable
ARM_ERRATA_814220 for proper workaround.
