Subject: [PATCH v2 01/21] openrisc: prefer memblock APIs returning virtual address
Date: Mon, 21 Jan 2019 10:03:48 +0200	[thread overview]
Message-ID: <1548057848-15136-2-git-send-email-rppt@linux.ibm.com> (raw)
In-Reply-To: <1548057848-15136-1-git-send-email-rppt@linux.ibm.com>

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.
