Nothing in the codebase was using them, and as written they took "unsigned long" as the physical address rather than "phys_addr_t", which is wrong on tilepro anyway. Rather than fixing stale APIs, just remove them; if there's ever demand for them on this platform, we can put them back. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

The tilegx PCI root complex support (currently only in linux-next) is limited to pages that are homed on cached in the default manner, i.e. "hash-for-home". This change supports delivery of I/O data to pages that are cached in other ways (locally on a particular core, uncached, user-managed incoherent, etc.). A large part of the change is supporting flushing pages from cache on particular homes so that we can transition the data that we are delivering to or from the device appropriately. The new homecache_finv* routines handle this. Some changes to page_table_range_init() were also required to make the fixmap code work correctly on tilegx; it hadn't been used there before. We also remove some stub mark_caches_evicted_*() routines that were just no-ops anyway. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

TILE doesn't support PAGE_KERNEL_NOCACHE so the macro isn't useful; it's a copy-and-paste from the first version of this header in 2007. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

This change is the core kernel support for TILEPro and TILE64 chips. No driver support (except the console driver) is included yet. This includes the relevant Linux headers in asm/; the low-level low-level "Tile architecture" headers in arch/, which are shared with the hypervisor, etc., and are build-system agnostic; and the relevant hypervisor headers in hv/.

Add a set of entries to the fixmap table to allow usage of known reserved virtual address space by early debug code. The address space reserved is the top 128K of the 32-bit address space. This allows, if required, the use of a BAT to do the mappings.

Make FIXADDR_TOP a compile time constant and cleanup a couple of definitions relative to the layout of the kernel address space on ppc32. We also print out that layout at boot time for debugging purposes. This is a pre-requisite for properly fixing non-coherent DMA allocactions.

This patch tweaks the way some PTE bit combinations are defined, in such a way that the 32 and 64-bit variant become almost identical and that will make it easier to bring in a new common pte-* file for the new variant of the Book3-E support. The combination of bits defining access to kernel pages are now clearly separated from the combination used by userspace and the core VM. The resulting generated code should remain identical unless I made a mistake. Note: While at it, I removed a non-sensical statement related to CONFIG_KGDB in ppc_mmu_32.c which could cause kernel mappings to be user accessible when that option is enabled. Probably something that bitrot. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

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 <asm-powepc/...> 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: NStephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: NPaul Mackerras <paulus@samba.org>

The fixmap code from x86 allows us to have compile time virtual addresses that we change the physical addresses of at run time. This is useful for applications like kmap_atomic, PCI config that is done via direct memory map, kexec/kdump. We got ride of CONFIG_HIGHMEM_START as we can now determine a more optimal location for PKMAP_BASE based on where the fixmap addresses start and working back from there. Additionally, the kmap code in asm-powerpc/highmem.h always had debug enabled. Moved to using CONFIG_DEBUG_HIGHMEM to determine if we should have the extra debug checking.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
