Subject: [PATCH v2 08/21] memblock: drop __memblock_alloc_base()
Date: Mon, 21 Jan 2019 10:03:55 +0200 [thread overview]
Message-ID: <1548057848-15136-9-git-send-email-rppt@linux.ibm.com> (raw)
In-Reply-To: <1548057848-15136-1-git-send-email-rppt@linux.ibm.com>
The __memblock_alloc_base() function tries to allocate a memory up to the
limit specified by its max_addr parameter. Depending on the value of this
parameter, the __memblock_alloc_base() can is replaced with the appropriate
memblock_phys_alloc*() variant.
