Ken Cox 60e1741fc3 Staging: unisys: Remove unused macros from visorchannel/visorchannel.h
VISORCHANNEL_CHANGE_SERVER_STATE and VISORCHANNEL_CHANGE_CLIENT_STATE
are never used in any of the source so they have been removed.

VISORCHANNEL_CHANGE_CLIENT_STATE would have caused a broken kernel build
after commit  a8d7f21d, but since it was never used the kernel continued
to build.

Ken Cox fcd0157ece Staging: unisys: detect s-Par firmware
This patch adds support for detection of s-Par firmware by checking for
the hypervisor bit in the CPU capabilities, and then querying the hypervisor
ID cpuid leaf.

This functionality will be used by the unisys drivers to determine if
they are being loaded on an s-Par platform and refuse to load if no
s-Par firmware is present.

This fixes a problem reported from upstream where a panic occurs if the
unisys drivers are loaded on a non s-Par system.

Greg Kroah-Hartman 806192c07d Staging: unisys: mark drivers as BROKEN
Turns out these drivers like to mess around with the system even if the
hardware they control isn't present.  That's not good, and people are
starting to report lots of issues with this in their build/boot testing.

So for now, let's just mark them as BROKEN, until the code gets
converted to use the proper driver model interaction (i.e. don't do
anything until the hardware is actually found in the system.)

Ken Cox 61a0bc0f1f Staging: unisys: Fix multiple variable length array declarations
There were multiple variable length arrays declared on the stack in proc
handlers:
	char buf[count];

I changed these to be fixed length arrays.

Ken Cox 27dd554839 Staging: unisys: uislib: Fix locking in info_proc_read_helper()
Make sure BusListLock is unlocked before returning.  If an error is encountered
early on in info_proc_read_helper() the function can return without unlocking.

Also changed the PROCLINE macro so that it doesn't include a goto statement.
