Subject: [PATCH v4 05/18] cxl: Rename some bare-metal specific functions
Date: Tue, 16 Feb 2016 22:38:58 +0100
From: Frederic Barrat <fbar...@linux.vnet.ibm.com>
To: imun...@au1.ibm.com, michael.neul...@au1.ibm.com,
m...@ellerman.id.au, linuxppc-dev@lists.ozlabs.org
Rename a few functions, changing the 'cxl_' prefix to either
'cxl_pci_' or 'cxl_native_', to make clear that the implementation is
bare-metal specific.
Those functions will have an equivalent implementation for a guest in
a later patch.
