2013-08-14powerpc: Better split CONFIG_PPC_INDIRECT_PIO and CONFIG_PPC_INDIRECT_MMIOBenjamin Herrenschmidt
Remove the generic PPC_INDIRECT_IO and ensure we only add overhead to the right accessors. IE. If only CONFIG_PPC_INDIRECT_PIO is set, we don't add overhead to all MMIO accessors. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-06-21powerpc: Replace find_linux_pte with find_linux_pte_or_hugepteAneesh Kumar K.V
Replace find_linux_pte with find_linux_pte_or_hugepte and explicitly document why we don't need to handle transparent hugepages at callsites. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-01-03POWERPC: drivers: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2011-10-31powerpc: io-workarounds.c was implicitly getting init_mmPaul Gortmaker
It was coming in via device.h --> module.h etc. but we want to clean that up. So explicitly include the header where init_mm is being declared. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
