The coding-styles.rst states, that multiline comments should
allways contain a leading "*" in each line.
For multiline comments in general they
/*
* should look
* like this.
*/
For multiline comments in either net/ or drivers/net/ however,
they should
/* omit
* the first
* empty line.
*/
Since this file is part of a networking driver, the goal for it would
be to reside in drivers/net/ one day.
This patch changes comments, that were in neither form of the two listed
above, to have the style that is specified for drivers/net/.

As stated in coding-styles.rst multiline comments should be structured in a way,
that the actual comment starts on the second line of the commented portion. E.g:
/*
* Multiline comments
* should look like
* this.
*/
However, there is an exception to files in drivers/net/ and net/, where
multiline comments are prefered to look like this:
/* Mutliline comments for
* drivers/net/ should look
* like this.
*/
The comments in this file initially looked like the first example.
But since this file is part of a networking driver and thus should
be moved to drivers/net/ one day, this patch adjusts the comments
such that they are fitting to the style imposed for drivers/net/.

The mt7621 has two network interfaces, one that connects to an
internal switch, and one that can connect to either that switch
or an external phy, or possibly an internal phy.
The Gnubee-PC2 has an external phy for use with the second interface.
This patch add some support for the second interface to mt7621.dtsi
and add a gbpc2.dts which makes use of this. This allows the second
interface to be used.
I don't fully understand how to configure this interface - the
documentation is thin - so there could well be room for improvement
here.

Like all lz77-based algrithms, lz4 has a dynamically populated
("sliding window") dictionary and the maximum lookback distance
is 65535. Therefore the number of bounced pages could be limited
by erofs based on this property.
However, just now we observed some lz4 sequences in the extreme
case cannot be decompressed correctly after this feature is enabled,
the root causes after analysis are clear as follows:
1) max bounced pages should be 17 rather than 16 pages;
2) considering the following case, the broken implementation
could reuse unsafely in advance (in other words, reuse it
less than a safe distance),
0 1 2 ... 16 17 18 ... 33 34
b p b b
note that the bounce page that we are concerned was allocated
at 0, and it reused at 18 since page 17 exists, but it mis-reused
at 34 in advance again, which causes decompress failure.
This patch resolves the issue by introducing a bitmap to mark
whether the page in the same position of last round is a bounced
page or not, and a micro stack data structure to store all
available bounced pages.

On SEC1, hash provides wrong result when performing hashing in several
steps with input data SG list has more than one element. This was
detected with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS:

This is due to two issues:
- We have an overlap between the buffer used for copying the input
data (SEC1 doesn't do scatter/gather) and the chained descriptor.
- Data copy is wrong when the previous hash left less than one
blocksize of data to hash, implying a complement of the previous
block with a few bytes from the new request.
Fix it by:
- Moving the second descriptor after the buffer, as moving the buffer
after the descriptor would make it more complex for other cipher
operations (AEAD, ABLKCIPHER)
- Skip the bytes taken from the new request to complete the previous
one by moving the SG list forward.

The SR-IOV specification requires both PFs and VFs to implement a PCIe
capability. Generally this is sufficient to assume extended config space
is present, but we generally also perform additional tests to make sure the
extended config space is reachable and not simply an alias of standard
config space. For a VF to exist extended config space must be accessible
on the PF, therefore we can also assume it to be accessible on the VF.
This enables a micro performance optimization previously implemented in
commit 975bb8b4dc93 ("PCI/IOV: Use VF0 cached config space size for other
VFs") to speed up probing of VFs.

Revert 975bb8b4dc93 ("PCI/IOV: Use VF0 cached config space size for other
VFs"), which attempted to cache the config space size from the first VF to
re-use for subsequent VFs.
The cached value was determined prior to discovering the PCIe capability on
the VF, which resulted in the first VF reporting the correct config space
size (4K), as it has a special case through pci_cfg_space_size(), while all
the other VFs only reported 256 bytes. As this was only a performance
optimization, we're better off without it.

into microseconds
Refer to the Intel SDM Vol.4, the package C-state residency counters
of modern IA micro-architecture are all ticking in TSC frequency,
hence we can apply simple math to transform the ticks into microseconds.
i.e.,
residency (ms) = count / tsc_khz
residency (us) = count / tsc_khz * 1000
This also aligns to other sysfs debug entries of residency counter in
the same metric in microseconds, benefits reading and scripting.

Modify DMI matching order: perform matching based on DMI_BOARD_NAME
before matching based on DMI_BOARD_VENDOR and DMI_PRODUCT_NAME in order
to reduce the number of ‘dmi_table’ entries necessary for new systems
support and keep matching order in logical way.
For example, the existing check for DMI_PRODUCT_NAME with prefixes
“MSN27", “MSN24”, "MSB” matches systems MSN2700-BXXXX, MSN2700-XXXX,
MSN2410-BXXXX, MSB7800-XXXX, where ‘XXXX’ specifies some systems
hardware flavors.
At the same time these systems also matched by DMI_BOARD_NAME
“VMOD0001”, because they all have the same platform configuration (LED,
interrupt control, mux etcetera).
New systems with different platform configuration, but with similar
DMI_PRODUCT_NAME MSN2700-2XXXX, MSN2700-2XXXX, MSB7800-2XXXX are about
to be added. These system have similar DMI_PRODUCT_NAME, since they
have same ports configuration as their predecessors. All new systems
will be matched by DMI_BOARD_NAME “VMOD0008”.
With the change provided in the patch it is enough just to add
“VMOD0008” match following natural after “VMOD0007”, otherwise
“VMOD0008” or all “MSN2700-2XXXX”, “MSN2700-2XXXX”, “MSB7800-2XXXX”
should be added on top of ‘mlxplat_dmi_table” in order to be matched
before “MSN27", “MSN24”, "MSB”.

Move the existing clocksource code under drivers/hv and arch/x86 to the new
clocksource driver while separating out the ISA dependencies. Update
Hyper-V initialization to call initialization and cleanup routines since
the Hyper-V synthetic clock is not independently enumerated in ACPI.
Update Hyper-V clocksource users in KVM and VDSO to get definitions from
the new include file.
No behavior is changed and no new functionality is added.

Hyper-V clock/timer code and data structures are currently mixed
in with other code in the ISA independent drivers/hv directory as
well as the ISA dependent Hyper-V code under arch/x86.
Consolidate this code and data structures into a Hyper-V clocksource driver
to better follow the Linux model. In doing so, separate out the ISA
dependent portions so the new clocksource driver works for x86 and for the
in-process Hyper-V on ARM64 code.
To start, move the existing clockevents code to create the new clocksource
driver. Update the VMbus driver to call initialization and cleanup routines
since the Hyper-V synthetic timers are not independently enumerated in
ACPI.
No behavior is changed and no new functionality is added.

so the hyper-v clocksource update can be applied.

The ASPEED pinctrl driver implementations make heavy use of macros to
minimise tedium of implementation and maximise the chance that the
compiler will catch errors in defining signal and pin configurations.
While the goal of minimising errors is achieved, it is at the cost of
the complexity of the macros.
Document examples of the expanded form of pin declarations to
demonstrate the operation of the macros.

ASPEED have completely rearranged the System Control Unit register
layout with the AST2600. The existing code took advantage of the fact
that the AST2400 and AST2500 had layouts that were similar enough to
have little impact on the pinmux infrastructure (though there is a wart
with read-modify-write vs write-1-clear semantics of the hardware
strapping registers between the two).
Given that any similarity has been thrown out with the AST2600, separate
out the function applying an expression state to be driver-specific.
With it, extract out the pinmux macro jungle to its own header and
implementation so the pieces can be composed without dependency cycles.

Writes of 1 to SCU7C clear set bits in SCU70, the hardware strapping
register. The information was correct if you squinted while reading, but
hopefully switching the order of the registers as listed conveys it
better.
