[PATCH AUTOSEL 5.10 5/7] drm: panel-orientation-quirks: Add quirk for Lenovo Yoga Book X90F

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 03aecb1acbcd7a660f97d645ca6c09d9de27ff9d ]

Like the Windows Lenovo Yoga Book X91F/L the Android Lenovo Yoga Book
X90F/L has a portrait 1200x1920 screen used in landscape mode,
add a quirk for this.

When the quirk for the X91F/L was initially added it was written to
also apply to the X90F/L but this does not work because the Android
version of the Yoga Book uses completely different DMI strings.
Also adjust the X91F/L quirk to reflect that it only applies to
the X91F/L models.

[PATCH AUTOSEL 5.10 6/7] verify_pefile: relax wrapper length check

[Sasha Levin]

From: Robbie Harwood <rharwood@redhat.com>

[ Upstream commit 4fc5c74dde69a7eda172514aaeb5a7df3600adb3 ]

The PE Format Specification (section "The Attribute Certificate Table
(Image Only)") states that `dwLength` is to be rounded up to 8-byte
alignment when used for traversal.  Therefore, the field is not required
to be an 8-byte multiple in the first place.

Accordingly, pesign has not performed this alignment since version
0.110.  This causes kexec failure on pesign'd binaries with "PEFILE:
Signature wrapper len wrong".  Update the comment and relax the check.

[PATCH AUTOSEL 5.10 7/7] asymmetric_keys: log on fatal failures in PE/pkcs7

[Sasha Levin]

From: Robbie Harwood <rharwood@redhat.com>

[ Upstream commit 3584c1dbfffdabf8e3dc1dd25748bb38dd01cd43 ]

These particular errors can be encountered while trying to kexec when
secureboot lockdown is in place.  Without this change, even with a
signed debug build, one still needs to reboot the machine to add the
appropriate dyndbg parameters (since lockdown blocks debugfs).

Accordingly, upgrade all pr_debug() before fatal error into pr_warn().
