Subject: [PATCH v2 03/21] memblock: replace memblock_alloc_base(ANYWHERE) with memblock_phys_alloc
Date:   Mon, 21 Jan 2019 10:03:50 +0200
In-Reply-To: <1548057848-15136-1-git-send-email-rppt@linux.ibm.com>
References: <1548057848-15136-1-git-send-email-rppt@linux.ibm.com>
Message-Id: <1548057848-15136-4-git-send-email-rppt@linux.ibm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The calls to memblock_alloc_base(size, align, MEMBLOCK_ALLOC_ANYWHERE) and
memblock_phys_alloc(size, align) are equivalent as both try to allocate
'size' bytes with 'align' alignment anywhere in the memory and panic if hte
allocation fails.

The conversion is done using the following semantic patch:

@@
expression size, align;
@@
- memblock_alloc_base(size, align, MEMBLOCK_ALLOC_ANYWHERE)
+ memblock_phys_alloc(size, align)
