In commit 54321242afe ("Disable interrupts early in Program Check"), we
switched from enabling to disabling interrupts in program_check_common.
Whereas ENABLE_INTS leaves r3 untouched, if lockdep is enabled DISABLE_INTS
calls into lockdep code and will clobber r3. That means we pass a bogus
struct
Discard the old way that invoke hypercall,
instead, use epapr paravirt.

The perf code has grown a lot since it started, and is big enough to
warrant its own subdirectory. For reference it's ~60% bigger than the
oprofile code. It declutters the kernel directory, makes it simpler to
grep for "just perf stuff", and allows us to shorten some filenames.
While we're at it,

Grant,
This seems to be broken in your tree (since 301b605ff6), so you should
probably pick up this patch.

Hmmm... the patch you posted is a good short-term fix, but I wonder if
makes sense for the driver to support modules at all. I have this in the
driver:
#include
...
module_init(ehv_bc_init);
module_exit(ehv_bc_exit);
