kernel - Deal with lost IPIs (VM related) (2)
* Fix an issue where Xinvltlb interacts badly with a drm console
framebuffer,
imploding the machine. The 1/16 second watchdog can trigger during
certain
DRM operations due to excessive interrupt disablement in the linux DRM
code.
* Avoid kprintf()ing anything by default.
* Also make a minor fix to the watchdog logic to force the higher-level
Xinvltlb loop to re-test.
