Subject: [patch 094/128] powerpc: add an ioremap_phb helper
Date: Mon, 01 Jun 2020 21:50:37 -0700	[thread overview]
Message-ID: <20200602045037._6QEURref%akpm@linux-foundation.org> (raw)
In-Reply-To: <20200601214457.919c35648e96a2b46b573fe1@linux-foundation.org>

From: Christoph Hellwig <hch@lst.de>
Subject: powerpc: add an ioremap_phb helper

Factor code shared between pci_64 and electra_cf into a ioremap_pbh helper
that follows the normal ioremap semantics, and returns a useful __iomem
pointer.  Note that it opencodes __ioremap_at as we know from the callers
the slab is available.  Switch pci_64 to also store the result as __iomem
pointer, and unmap the result using iounmap instead of force casting and
using vmalloc APIs.
