9e5d6b982c platform/x86: thinkpad_acpi: Do hkey to scancode translation later
Modify hotkey_notify_hotkey() and it helpers to mostly directly operate
on hkey codes (TP_HKEY_EV_* returned by "MHKP") instead of on the 0 -
TPACPI_HOTKEY_MAP_LEN scancodes used for scancode -> keycode translation.

Keeping things in the hkey format as long a possible is a bit cleaner and
this patch prepares things for moving to sparse-keymaps.

d761684afd platform/x86: thinkpad_acpi: Use tpacpi_input_send_key() in adaptive kbd code
Use tpacpi_input_send_key() in adaptive_keyboard_hotkey_notify_hotkey()
instead of re-implementing it there.

Note this change will also result in a behavioral change, key presses on
the adaptive keyboard will now also send a EV_MSC event with the scancode,
just like all other hotkey presses already do. This is not a bug but
a feature.

400fea4b96 x86/sev: Add callback to apply RMP table fixups for kexec
Handle cases where the RMP table placement in the BIOS is not 2M aligned
and the kexec-ed kernel could try to allocate from within that chunk
which then causes a fatal RMP fault.

The kexec failure is illustrated below:

  SEV-SNP: RMP table physical range [0x0000007ffe800000 - 0x000000807f0fffff]
  BIOS-provided physical RAM map:
  BIOS-e820: [mem 0x0000000000000000-0x000000000008efff] usable
  BIOS-e820: [mem 0x000000000008f000-0x000000000008ffff] ACPI NVS
  ...
  BIOS-e820: [mem 0x0000004080000000-0x0000007ffe7fffff] usable
  BIOS-e820: [mem 0x0000007ffe800000-0x000000807f0fffff] reserved
  BIOS-e820: [mem 0x000000807f100000-0x000000807f1fefff] usable

As seen here in the e820 memory map, the end range of the RMP table is not
aligned to 2MB and not reserved but it is usable as RAM.

Subsequently, kexec -s (KEXEC_FILE_LOAD syscall) loads it's purgatory
code and boot_param, command line and other setup data into this RAM
region as seen in the kexec logs below, which leads to fatal RMP fault
during kexec boot.

Check if RMP table start and end physical range in the e820 tables are
not aligned to 2MB and in that case map this range to reserved in all
the three e820 tables.

cd42ba1c8a net: give more chances to rcu in netdev_wait_allrefs_any()
This came while reviewing commit c4e86b4363 ("net: add two more

Paolo asked if adding one synchronize_rcu() would help.

While synchronize_rcu() does not help, making sure to call
rcu_barrier() before msleep(wait) is definitely helping
to make sure lazy call_rcu() are completed.

Instead of waiting ~100 seconds in my tests, the ref_tracker
splats occurs one time only, and netdev_wait_allrefs_any()
latency is reduced to the strict minimum.

Ideally we should audit our call_rcu() users to make sure
no refcount (or cascading call_rcu()) is held too long,
because rcu_barrier() is quite expensive.

a2c72ed78a mcb: lpc: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

bd25a3f5ed platform/x86/intel/ifs: Disable irq during one load stage
One of the stages in IFS image loading process involves loading individual
chunks (test patterns) from test image file to secure memory.

Driver issues a WRMSR(MSR_AUTHENTICATE_AND_COPY_CHUNK) operation to do
this. This operation can take up to 5 msec, and if an interrupt occurs
in between, the AUTH_AND_COPY_CHUNK u-code implementation aborts the
operation.

Interrupt sources such as NMI or SMI are handled by retrying. Regular
interrupts may occur frequently enough to prevent this operation from ever
completing. Disable irq on local cpu around the aforementioned WRMSR to
allow the operation to complete.

02153e5dcb platform/x86/intel/ifs: Classify error scenarios correctly
"Scan controller error" means that scan hardware encountered an error
prior to doing an actual test on the target CPU. It does not mean that
there is an actual cpu/core failure. "scan signature failure" indicates
that the test result on the target core did not match the expected value
and should be treated as a cpu failure.

Current driver classifies both these scenarios as failures. Modify
the driver to classify this situation with a more appropriate "untested"
status instead of "fail" status.
