staging: unisys: visorchannel: Add peek function
According to unisys, the s_par hypervisor has a bug in which it never
triggers an interrupt. That makes the visornic effectively a 2ms poll
loop. In order to just have the rx thread shceduling a napi poll every
2ms, lets instead give it the chance to check the response queue for
data before we schedule. This helper provides that functionality

staging: unisys: visornic_resume needs to mirror _serverdown_complete
Previously we simplified the serverdown function to basically turn it
into a dev_close(), but missed the analogous logic in visornic_resume()
(which is essentially the "book-end" of visornic_serverdown_complete()).
As a result, during IO partition recovery, the nic would go closed when
the IO partition went away, but would never be opened again when the IO
partition came back.
This patch changes visornic_resume() to use dev_open(), so that it once
again plays nicely with visornic_serverdown_complete(). Because
dev_open() forces us into the visornic_open() path, other logic in
visornic_resume() was no longer necessary, and lended to simplifying
visornic_resume() even more.

x86/mm/pat: Revert 'Adjust default caching mode translation tables'
Toshi explains:
"No, the default values need to be set to the fallback types,
i.e. minimal supported mode. For WC and WT, UC is the fallback type.
When PAT is disabled, pat_init() does update the tables below to
enable WT per the default BIOS setup. However, when PAT is enabled,
but CPU has PAT -errata, WT falls back to UC per the default values."

The CQM task events are not safe to be called from within interrupt
context because they require performing an IPI to read the counter value
on all sockets. And performing IPIs from within IRQ context is a
"no-no".
Make do with the last read counter value currently event in
event->count when we're invoked in this context.
