Pull in the fixes we sent during 4.7, we have code we want to merge into next that depends on some of them.

powerpc: Initialise pci_io_base as early as possible

2016-06-30T06:52:29Z

Commit d6a9996e84ac ("powerpc/mm: vmalloc abstraction in preparation for radix") turned kernel memory and IO addresses from #defined constants to variables initialised at runtime. On PA6T (pasemi) systems the setup_arch() machine call initialises the onboard PCI-e root-ports, and uses pci_io_base to do this, which is now before its value has been set, resulting in a panic early in boot before console IO is initialised. Move the pci_io_base initialisation to the same place as vmalloc ranges are set (hash__early_init_mmu()/radix__early_init_mmu()) - this is the earliest possible place we can initialise it.

powerpc/mm: vmalloc abstraction in preparation for radix

2016-05-11T11:53:53Z

The vmalloc range differs between hash and radix config. Hence make VMALLOC_START and related constants a variable which will be runtime initialized depending on whether hash or radix mode is active.

powerpc/mm: Use a helper for finding pte bits mapping I/O area

2016-05-01T08:32:32Z

Use a helper instead of open coding with constants. A later patch will drop the WIMG bits and use PowerISA 3.0 defines. Signed-off-by: Aneesh Kumar K.V Signed-off-by: Michael Ellerman

Merge tag 'powerpc-3.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux

2014-12-12T01:48:14Z

Pull powerpc updates from Michael Ellerman: "Some nice cleanups like removing bootmem, and removal of __get_cpu_var(). There is one patch to mm/gup.c. This is the generic GUP implementation, but is only used by us and arm(64). We have an ack from Steve Capper, and although we didn't get an ack from Andrew he told us to take the patch through the powerpc tree. There's one cxl patch. This is in drivers/misc, but Greg said he was happy for us to manage fixes for it. There is an infrastructure patch to support an IPMI driver for OPAL. There is also an RTC driver for OPAL. We weren't able to get any response from the RTC maintainer, Alessandro Zummo, so in the end we just merged the driver.
