Subject: [PATCH 01/21] openrisc: prefer memblock APIs returning virtual address
Date: Wed, 16 Jan 2019 15:44:01 +0200 [thread overview]
Message-ID: <1547646261-32535-2-git-send-email-rppt@linux.ibm.com> (raw)
In-Reply-To: <1547646261-32535-1-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.
