xfrm_state_find."
This reverts commit c9f3f813d462c72dbe412cee6a5cbacf13c4ad5e.
This commit breaks transport mode when the policy template
has widlcard addresses configured, so revert it.

Subject: [PATCH 6/6] drm/i915/edp: Only use the alternate fixed mode if it's
asked for
In commit dc911f5bd8aa ("drm/i915/edp: Allow alternate fixed mode for
eDP if available."), the patch allows for the use of an alternate fixed
mode if it is available, but the patch was not ensuring that the only
time the alternate mode is used is when it is specifically requested.
This patch adds an additional comparison to intel_edp_compare_alt_mode
to ensure that we only use the alternate mode if it is directly
requested.
Fixes: dc911f5bd8aac ("Allow alternate fixed mode for eDP if available.")

Subject: [PATCH 7/7] x86/cpu, x86/pti: Do not enable PTI on AMD processors
AMD processors are not subject to the types of attacks that the kernel
page table isolation feature protects against. The AMD microarchitecture
does not allow memory references, including speculative references, that
access higher privileged data when running in a lesser privileged mode
when that access would result in a page fault.
Disable page table isolation by default on AMD processors by not setting
the X86_BUG_CPU_INSECURE feature, which controls whether X86_FEATURE_PTI
is set.
