powerpc/32: Add a missing include header

2018-08-03T05:50:30Z

[ Upstream commit c89ca593220931c150cffda24b4d4ccf82f13fc8 ] The header file was missing from the includes. Fix the following warning, treated as error with W=1: arch/powerpc/kernel/pci_32.c:286:6: error: no previous prototype for ‘sys_pciconfig_iobase’ [-Werror=missing-prototypes] Signed-off-by: Mathieu Malaterre Signed-off-by: Michael Ellerman Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

powerpc: Convert to using %pOF instead of full_name

2017-08-23T12:27:04Z

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

Replace with globally

2016-12-24T19:46:01Z

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

powerpc: Remove more traces of bootmem

2014-11-19T10:41:51Z

Although we are now selecting NO_BOOTMEM, we still have some traces of bootmem lying around. That is because even with NO_BOOTMEM there is still a shim that converts bootmem calls into memblock calls, but ultimately we want to remove all traces of bootmem. Most of the patch is conversions from alloc_bootmem() to memblock_virt_alloc(). In general a call such as: p = (struct foo *)alloc_bootmem(x); Becomes: p = memblock_virt_alloc(x, 0); We don't need the cast because memblock_virt_alloc() returns a void *. The alignment value of zero tells memblock to use the default alignment, which is SMP_CACHE_BYTES, the same value alloc_bootmem() uses. We remove a number of NULL checks on the result of memblock_virt_alloc(). That is because memblock_virt_alloc() will panic if it can't allocate, in exactly the same way as alloc_bootmem(), so the NULL checks are and always have been redundant. The memory returned by memblock_virt_alloc() is already zeroed, so we remove several memsets of the result of memblock_virt_alloc(). Finally we convert a few uses of __alloc_bootmem(x, y, MAX_DMA_ADDRESS) to just plain memblock_virt_alloc(). We don't use memblock_alloc_base() because MAX_DMA_ADDRESS is ~0ul on powerpc, so limiting the allocation to that is pointless, 16XB ought to be enough for anyone. Signed-off-by: Michael Ellerman

powerpc/pci: Support per-aperture memory offset

2013-05-06T03:40:40Z

The PCI core supports an offset per aperture nowadays but our arch code still has a single offset per host bridge representing the difference betwen CPU memory addresses and PCI MMIO addresses. This is a problem as new machines and hypervisor versions are coming out where the 64-bit windows will have a different offset (basically mapped 1:1) from the 32-bit windows. This fixes it by using separate offsets. In the long run, we probably want to get rid of that intermediary struct pci_controller and have those directly stored into the pci_host_bridge as they are parsed but this will be a more invasive change.

POWERPC: drivers: remove __dev* attributes.

2013-01-03T23:57:04Z

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.

powerpc+of: Rename the drivers/of prom_* functions to of_*

Rename the prom_*_property routines of the generic OF code to of_*_property. This brings them in line with the naming used by the rest of the OF code. Signed-off-by: Nathan Fontenot Acked-by: Geoff Levand Acked-by: Rob Herring Acked-by: Grant Likely Signed-off-by: Benjamin Herrenschmidt

powerpc/PCI: compute I/O space bus-to-resource offset consistently

2012-03-20T17:41:44Z

Make sure we compute CPU addresses (resource start/end) the same way both when we set up the I/O aperture (hose->io_resource) and when we use pcibios_bus_to_resource() to convert BAR values into resources. This fixes a build failure ("cast from pointer to integer of different size" in configs where resource_size_t is 64 bits but pointers are 32 bits) I introduced in 6c5705fec63d.
