For both PASID-based-Device-TLB Invalidate Descriptor and
Device-TLB Invalidate Descriptor, the Physical Function Source-ID
value is split according to this layout:
PFSID[3:0] is set at offset 12 and PFSID[15:4] is put at offset 52.
Fix the part laid out at offset 52.

The intel-iommu driver assumes that the iommu state is
cleaned up at the start of the new kernel.
But, when we try to kexec boot something other than the
Linux kernel, the cleanup cannot be relied upon.
Hence, cleanup before we go down for reboot.
Keeping the cleanup at initialization also, in case BIOS
leaves the IOMMU enabled.
I considered turning off iommu only during kexec reboot, but a clean
shutdown seems always a good idea. But if someone wants to make it
conditional, such as VMM live update, we can do that. There doesn't
seem to be such a condition at this time.
Tested that before, the info message
'DMAR: Translation was enabled for <iommu> but we are not in kdump mode'
would be reported for each iommu. The message will not appear when the
DMA-remapping is not enabled on entry to the kernel.

A proper External Memory Controller clock rounding and parent selection
functionality is required by the EMC drivers, it is not available using
the generic clock implementation because only the Memory Controller driver
is aware of what clock rates are actually available for a particular
device. EMC drivers will have to register a Tegra-specific CLK-API
callback which will perform rounding of a requested rate. EMC clock users
won't be able to request EMC clock by getting -EPROBE_DEFER until EMC
driver is probed and the callback is set up.
The functionality is somewhat similar to the clk-emc.c which serves
Tegra124+ SoCs. The later HW generations support more parent clock sources
and the HW configuration / integration with the EMC drivers differs a tad
from the older gens, hence it's not really worth to try to squash
everything into a single source file.

Quota statistics counted as 64-bit per-cpu counter. Reading sums per-cpu
fractions as signed 64-bit int, filters negative values and then reports
lower half as signed 32-bit int.
Result may looks like:
fs.quota.allocated_dquots = 22327
fs.quota.cache_hits = -489852115
fs.quota.drops = -487288718
fs.quota.free_dquots = 22083
fs.quota.lookups = -486883485
fs.quota.reads = 22327
fs.quota.syncs = 335064
fs.quota.writes = 3088689
Values bigger than 2^31-1 reported as negative.
All counters except "allocated_dquots" and "free_dquots" are monotonic,
thus they should be reported as is without filtering negative values.
Kernel doesn't have generic helper for 64-bit sysctl yet,
let's use at least unsigned long.

As seen on the new Raspberry Pi 4 and sta2x11's DMA implementation it is
possible for a device configured with 32 bit DMA addresses and a partial
DMA mapping located at the end of the address space to overflow. It
happens when a higher physical address, not DMAable, is translated to
it's DMA counterpart.
For example the Raspberry Pi 4, configurable up to 4 GB of memory, has
an interconnect capable of addressing the lower 1 GB of physical memory
with a DMA offset of 0xc0000000. It transpires that, any attempt to
translate physical addresses higher than the first GB will result in an
overflow which dma_capable() can't detect as it only checks for
addresses bigger then the maximum allowed DMA address.
Fix this by verifying in dma_capable() if the DMA address range provided
is at any point lower than the minimum possible DMA address on the bus.

For dma-direct we know that the DMA address is an encoding of the
physical address that we can trivially decode. Use that fact to
provide implementations that do not need the arch_dma_coherent_to_pfn
architecture hook. Note that we still can only support mmap of
non-coherent memory only if the architecture provides a way to set an
uncached bit in the page tables. This must be true for architectures
that use the generic remap helpers, but other architectures can also
manually select it.

There is a distinct version of the Ux500 U8420 variant
with "sysclk", as can be seen from the vendor code that
didn't make it upstream, this firmware lacks the
ULPPLL (ultra-low power phase locked loop) which in
effect means that the timer clock is instead wired to
the 32768 Hz always-on clock.
This has some repercussions when enabling the timer
clock as the code as it stands will disable the timer
clock on these platforms (lacking the so-called
"doze mode") and obtaining the wrong rate of the timer
clock.
The timer frequency is of course needed very early in
the boot, and as a consequence, we need to shuffle
around the early PRCMU init code: whereas in the past
we did not need to look up the PRCMU firmware version
in the early init, but now we need to know the version
before the core system timers are registered so we
restructure the platform callbacks to the PRCMU so as
not to take any arguments and instead look up the
resources it needs directly from the device tree
when initializing.
As we do not yet support any platforms using this
firmware it is not a regression, but as PostmarketOS
is starting to support products with this firmware we
need to fix this up.
The low rate of 32kHz also makes the MTU timer unsuitable
as delay timer but this needs to be fixed in a separate
patch.

spi_nor_unlock() unlocks blocks of memory or the entire flash memory
array, if requested. clear_sr_bp() unlocks the entire flash memory
array at boot time. This calls for some unification, clear_sr_bp() is
just an optimization for the case when the unlock request covers the
entire flash size.
Get rid of clear_sr_bp() and introduce spi_nor_unlock_all(), which is
just a call to spi_nor_unlock() for the entire flash memory array.
This fixes a bug that was present in spi_nor_spansion_clear_sr_bp().
When the QE bit was zero, we used the Write Status (01h) command with
one data byte, which might cleared the Status Register 2. We now always
use the Write Status (01h) command with two data bytes when
SNOR_F_HAS_16BIT_SR is set, to avoid clearing the Status Register 2.
The SNOR_F_NO_READ_CR case is treated as well. When the flash doesn't
support the CR Read command, we make an assumption about the value of
the QE bit. In spi_nor_init(), call spi_nor_quad_enable() first, then
spi_nor_unlock_all(), so that at the spi_nor_unlock_all() time we can
be sure the QE bit has value one, because of the previous call to
spi_nor_quad_enable().
Get rid of the MFR handling and implement specific manufacturer
default_init() fixup hooks.
Note that this changes a bit the logic for the SNOR_MFR_ATMEL,
SNOR_MFR_INTEL and SNOR_MFR_SST cases. Before this patch, the Atmel,
Intel and SST chips did not set the locking ops, but unlocked the entire
flash at boot time, while now they are setting the locking ops to
stm_locking_ops. This should work, since the disable of the block
protection at the boot time used the same Status Register bits to unlock
the flash, as in the stm_locking_ops case.

Make sure that when doing a lock() or an unlock() operation we don't clear
the QE bit from Status Register 2.
JESD216 revB or later offers information about the *default* Status
Register commands to use (see BFPT DWORDS[15], bits 22:20). In this
standard, Status Register 1 refers to the first data byte transferred on a
Read Status (05h) or Write Status (01h) command. Status register 2 refers
to the byte read using instruction 35h. Status register 2 is the second
byte transferred in a Write Status (01h) command.
Industry naming and definitions of these Status Registers may differ.
The definitions are described in JESD216B, BFPT DWORDS[15], bits 22:20.
There are cases in which writing only one byte to the Status Register 1
has the side-effect of clearing Status Register 2 and implicitly the Quad
Enable bit. This side-effect is hit just by the
BFPT_DWORD15_QER_SR2_BIT1_BUGGY and BFPT_DWORD15_QER_SR2_BIT1 cases.

On some SoCs the Adaptive Voltage Scaling (AVS) technique is
employed to optimize the operating voltage of a device. At a
given frequency, the hardware monitors dynamic factors and either
makes a suggestion for how much to adjust a voltage for the
current frequency, or it automatically adjusts the voltage
without software intervention. Add an API to the OPP library for
the former case, so that AVS type devices can update the voltages
for an OPP when the hardware determines the voltage should
change. The assumption is that drivers like CPUfreq or devfreq
will register for the OPP notifiers and adjust the voltage
according to suggestions that AVS makes.

There is no good reason why the unique_id needs to be stored as 4
bits. The code will work without changes with a u8 since all values
are already filtered while parsing the ACPI tables and Slave devID
registers.
Use u8 representation. This will allow us to encode a

The EDAC_DIMM_OFF() macro takes 5 arguments to get the DIMM's index.
Simplify this by storing the index in struct dimm_info to avoid its
calculation and remove the EDAC_DIMM_OFF() macro. The index can be
directly used then.
Another advantage is that edac_mc_alloc() could be used even if the
exact size of the layers is unknown. Only the number of DIMMs would be
needed.
Rename iterator variable to idx, while at it. The name is more handy,
esp. when searching for it in the code.

The EDAC_DIMM_PTR() macro takes 3 arguments from struct mem_ctl_info.
Clean up this interface to only pass the mci struct and replace this
macro with a new function edac_get_dimm().
Also introduce an edac_get_dimm_by_index() function for later use.
This allows it to get a DIMM pointer only by a given index. This can
be useful if the DIMM's position within the layers of the memory
controller or the exact size of the layers are unknown.
Small style changes made for some hunks after applying the semantic
patch.
