The mctp-lpc chardev is replaced (temporarily) by the raw KCS chardev.
The raw chardev is required for IBM's purposes until Jeremy's
socket-based MCTP patches are merged[1][2].

[ Upstream commit 79d341e26ebcdbc622348aaaab6f8f89b6fdb25f ]
hp_accel can take almost two seconds to resume on some HP laptops.
The bottleneck is on evaluating _INI, which is only needed to run once.
Resolve the issue by only invoking _INI when it's necessary. Namely, on
probe and on hibernation restore.

commit bda7d3ab06f19c02dcef61fefcb9dd954dfd5e4f upstream.
40cc3a80bb42 ("kgdb: fix gcc-11 warning on indentation") tried to fix up
the gcc-11 complaints in this file by just reformatting the #defines.
That worked for gcc 11.1.0, but in gcc 11.1.1 as shipped by Fedora 34,
the warning came back for one of the #defines.
Fix this up again by putting { } around the if statement, now it is
quiet again.

commit a73b6a3b4109ce2ed01dbc51a6c1551a6431b53c upstream.
In commit b05ae01fdb89, someone tried to make the driver handle i2c read
errors by simply zeroing out the register contents, but for some reason
left unaltered the code that sets the cached register value the function
call return value.
The original patch was authored by a member of the Underhanded
Mangle-happy Nerds, I'm not terribly surprised. I don't have the
hardware anymore so I can't test this, but it seems like a pretty
obvious API usage fix to me...

commit 3641762c1c9c7cfd84a7061a0a73054f09b412e3 upstream.
Before this commit lis3lv02d_get_pwron_wait() had a WARN_ONCE() to catch
a potential divide by 0. WARN macros should only be used to catch internal
kernel bugs and that is not the case here. We have been receiving a lot of
bug reports about kernel backtraces caused by this WARN.
The div value being checked comes from the lis3->odrs[] array. Which
is sized to be a power-of-2 matching the number of bits in lis3->odr_mask.
The only lis3 model where this array is not entirely filled with non zero
values. IOW the only model where we can hit the div == 0 check is the
3dc ("8 bits 3DC sensor") model:
int lis3_3dc_rates[16] = {0, 1, 10, 25, 50, 100, 200, 400, 1600, 5000};
Note the 0 value at index 0, according to the datasheet an odr index of 0
means "Power-down mode". HP typically uses a lis3 accelerometer for HDD
fall protection. What I believe is happening here is that on newer
HP devices, which only contain a SDD, the BIOS is leaving the lis3 device
powered-down since it is not used for HDD fall protection.
Note that the lis3_3dc_rates array initializer only specifies 10 values,
which matches the datasheet. So it also contains 6 zero values at the end.
Replace the WARN with a normal check, which treats an odr index of 0
as power-down and uses a normal dev_err() to report the error in case
odr index point past the initialized part of the array.

[ Upstream commit f6f1f8e6e3eea25f539105d48166e91f0ab46dd1 ]
A dummy zero bit is sent preceding the data during a read transfer by the
Microchip 93LC46B eeprom (section 2.7 of[1]). This results in right shift
of data during a read. In order to ignore this bit a quirk can be added to
send an extra zero bit after the read address.
Add a quirk to ignore the zero bit sent before data by adding a zero bit

Tested: Checked correct behavior (both read & write) on TYAN S7106
board by manually changing routing settings and confirming that bits
flow as expected. Tested for UART1 and UART3 as this board doesn't have
the other UARTs wired up in a testable way.

When PCH works under eSPI mode, the PMC (Power Management Controller) in
PCH is waiting for SUS_ACK from BMC after it alerts SUS_WARN. It is in
dead loop if no SUS_ACK assert. This is the basic requirement for the BMC
works as eSPI slave.
Also for the host power on / off actions, from BMC side, the following VW
(Virtual Wire) messages are done in firmware:
1. SLAVE_BOOT_LOAD_DONE / SLAVE_BOOT_LOAD_STATUS
2. SUS_ACK
3. OOB_RESET_ACK
4. HOST_RESET_ACK
Also, it provides monitoring interface of PLTRST_N signal through

When the VMCI host support releases guest memory in the case where
the VM was killed, the pinned guest pages aren't locked. Use
set_page_dirty_lock() instead of set_page_dirty().
Testing done: Killed VM while having an active VMCI based vSocket
connection and observed warning from ext4. With this fix, no
warning was observed. Ran various vSocket tests without issues.

device tree users
[ Upstream commit 4540b9fbd8ebb21bb3735796d300a1589ee5fbf2 ]
Module alias "spi:93xx46" is used by non device tree users like
drivers/misc/eeprom/digsy_mtc_eeprom.c and removing it will
break support for them.
Fix this by adding back the module alias "spi:93xx46".

commit 3f618ab3323407ee4c6a6734a37eb6e9663ebfb9 upstream.
When building with KASAN and LKDTM, clang may implictly generate an
asan.module_ctor function in the LKDTM rodata object. The Makefile moves
the lkdtm_rodata_do_nothing() function into .rodata by renaming the
file's .text section to .rodata, and consequently also moves the ctor
function into .rodata, leading to a boot time crash (splat below) when
the ctor is invoked by do_ctors().
Let's prevent this by marking the function as noinstr rather than
notrace, and renaming the file's .noinstr.text to .rodata. Marking the
function as noinstr will prevent tracing and kprobes, and will inhibit
any undesireable compiler instrumentation.
The ctor function (if any) will be placed in .text and will work
correctly.
Example splat before this patch is applied:

IBM have developed a vendor-defined MCTP binding that utilises LPC IO
and FW interfaces to exchange MCTP messages. A KCS device in the IO
space is used to send single-byte control messages initialising the MCTP
channel and exchanging ownership of data buffers.
This driver exposes the KCS message stream to userspace, allowing an
MCTP-capable application to manipulate the data exposed via the FW
space.
