Marios Pomonis 6367499bd6 KVM: x86: Protect ioapic_write_indirect() from Spectre-v1/L1TF attacks ...

commit 670564559c upstream.

This fixes a Spectre-v1/L1TF vulnerability in ioapic_write_indirect().
This function contains index computations based on the
(attacker-controlled) IOREGSEL register.

This patch depends on patch
"KVM: x86: Protect ioapic_read_indirect() from Spectre-v1/L1TF attacks".

Fixes: 70f93dae32 ("KVM: Use temporary variable to shorten lines.")
