From: Alexander Shishkin

Hi,

Here are 2 hardening fixes around MSIX table size/offset handling,
aiming to prevent a malicious device or VMM from triggering bugs by
supplying bogus values.

Alexander Shishkin (2):
PCI/MSI: Cache the MSIX table size
PCI/MSI: Validate device supplied MSI table offset and size
