[Xen-devel] [PATCH 01/21] openrisc: prefer memblock APIs returning virtual address

[Mike Rapoport <rppt@xxxxxxxxxxxxx>]

The allocation of the page tables memory in openrics uses
memblock_phys_alloc() and then converts the returned physical address to
virtual one. Use memblock_alloc_raw() and add a panic() if the allocation
fails.
