UIO framework requires the device memory aligned to page boundary.
Hyper-V may allocate some memory that is Hyper-V page aligned (4k)
but not system page aligned.
Fix this by having Hyper-V always allocate those pages on system page
boundary and expose them to user-mode.
Change in v2:
Added two more patches to the series:
"uio_hv_generic: Adjust ring size according to system page alignment"
"Drivers: hv: Remove hv_free/alloc_* helpers"
Added more details in the commit message of
"uio_hv_generic: Use correct size for interrupt and monitor pages"
Change in v3:
Rearranged the patch on removing hv_alloc/free* helpers
Added "Drivers: hv: Use kzalloc for panic page allocation"
Fixed typos.
