The block address is saved after the block is initialized when
threshold_init_device() is called.
Use the saved block address, if available, rather than trying to
rediscover it.
We can avoid some *on_cpu() calls in the init path that will cause a

Pass the bank number to smca_get_bank_type() since that's all we need.
Also, we should compare the bank number to the size of the smca_banks
array not the number of bank types. Bank types are reused for multiple
banks, so the number of types can be different from the number o
From: Yazen Ghannam
Currently, bank 4 is reserved on Fam17h, so we chose not to initialize
bank 4 in the smca_banks array. This means that when we check if a bank
is initialized, like during boot or resume, we will see that bank 4 is
not initialized and try to initialize it. This may cause a call

Hi Hans,
Why don't modify the extcon-axp288.c after revert it?
Instead, you sent the patch[1]. Are you going to send other patch for
extcon-axp288.c?

Add direct access to MSR_IA32_SPEC_CTRL for guests. This is needed for
guests that will only mitigate Spectre V2 through IBRS+IBPB and will not
be using a retpoline+IBPB based approach.
To avoid the overhead of saving and restoring the MSR_IA32_SPEC_CTRL for
g
Intel processors use MSR_IA32_ARCH_CAPABILITIES MSR to indicate RDCL_NO
(bit 0) and IBRS_ALL (bit 1). This is a read-only MSR. By default the
contents will come directly from the hardware, but user-space can still
override it.

The Indirect Branch Predictor Barrier (IBPB) is an indirect branch
control mechanism. It keeps earlier branches from influencing
later ones.
Unlike IBRS and STIBP, IBPB does not define a new mode of operation.
It's a command that ensures predicted branch targets aren't used after
Add direct access to speculation control MSRs for KVM guests. This allows the
guest to protect itself against Spectre V2 using IBRS+IBPB instead of a
retpoline+IBPB based approach.
It also exposes the ARCH_CAPABILITIES MSR which is used by Intel processors to
indicate RDCL_NO and IBRS_ALL.

... basically doing exactly what we do for VMX:
- Passthrough SPEC_CTRL to guests (if enabled in guest CPUID)
- Save and restore SPEC_CTRL around VMExit and VMEntry only if the guest
actually used it.
