[PATCH 0/2] Fix uio_hv_generic on 64k page systems
From: longli

From: Long Li <longli@xxxxxxxxxxxxx>
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.
Long Li (2):
Drivers: hv: Allocate interrupt and monitor pages aligned to system
page boundary
uio_hv_generic: Use correct size for interrupt and monitor pages
