powerpc: Disable /dev/port interface on systems without an ISA bridge

2012-07-11T08:22:32Z

Some power systems do not have legacy ISA devices. So, /dev/port is not a valid interface on these systems. User level tools such as kbdrate is trying to access the device using this interface which is causing the system crash. This patch will fix this issue by not creating this interface on these powerpc systems. Signed-off-by: Haren Myneni Signed-off-by: Benjamin Herrenschmidt

powerpc: Remove ioremap_flags

2011-05-19T04:30:43Z

We have a confusing number of ioremap functions. Make things just a bit simpler by merging ioremap_flags and ioremap_prot. Signed-off-by: Anton Blanchard Signed-off-by: Benjamin Herrenschmidt

powerpc: Add ioremap_wc

2011-05-19T04:30:42Z

Add ioremap_wc so drivers can request write combining on kernel mappings. Signed-off-by: Anton Blanchard Signed-off-by: Benjamin Herrenschmidt

powerpc/pci: Split IO vs MMIO indirect access hooks

2011-04-27T04:18:27Z

The goal is to avoid adding overhead to MMIO when only PIO is needed Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Michael Ellerman Signed-off-by: Benjamin Herrenschmidt

powerpc: Wire up /proc/vmallocinfo to our ioremap()

2009-03-11T06:10:14Z

This adds the necessary bits and pieces to powerpc implementation of ioremap to benefit from caller tracking in /proc/vmallocinfo, at least for ioremap's done after mem init as the older ones aren't tracked. Signed-off-by: Benjamin Herrenschmidt

powerpc: Remove dead BIO_VMERGE_BOUNDARY definition

2008-12-16T04:53:19Z

The block layer dropped the virtual merge feature (b8b3e16cfe6435d961f6aaebcfd52a1ff2a988c5). BIO_VMERGE_BOUNDARY definition is meaningless now (For POWER, BIO_VMERGE_BOUNDARY has been meaningless for a long time since POWER disables the virtual merge feature).

POWERPC: Allow 32-bit hashed pgtable code to support 36-bit physical

2008-09-24T21:29:44Z

This rearranges a bit of code, and adds support for 36-bit physical addressing for configs that use a hashed page table. The 36b physical support is not enabled by default on any config - it must be explicitly enabled via the config system. This patch *only* expands the page table code to accomodate large physical addresses on 32-bit systems and enables the PHYS_64BIT config option for 86xx. It does *not* allow you to boot a board with more than about 3.5GB of RAM - for that, SWIOTLB support is also required (and coming soon). Signed-off-by: Becky Bruce Signed-off-by: Kumar Gala

powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00Z

from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras
