Also prototype the "compat" functions so they can be referenced from C code. Signed-off-by: Chris Metcalf Acked-by: Arnd Bergmann

Merge Qualcom Hexagon architecture

2011-11-01T14:48:13Z

This is the fifth version of the patchset (with one tiny whitespace fix) to the Linux kernel to support the Qualcomm Hexagon architecture. Between now and the next pull requests, Richard Kuo should have his key signed, etc., and should be back on kernel.org. In the meantime, this got merged as a emailed patch-series. * Hexagon: (36 commits) Add extra arch overrides to asm-generic/checksum.h Hexagon: Add self to MAINTAINERS Hexagon: Add basic stacktrace functionality for Hexagon architecture. Hexagon: Add configuration and makefiles for the Hexagon architecture. Hexagon: Comet platform support Hexagon: kgdb support files Hexagon: Add page-fault support. Hexagon: Add page table header files & etc. Hexagon: Add ioremap support Hexagon: Provide DMA implementation Hexagon: Implement basic TLB management routines for Hexagon. Hexagon: Implement basic cache-flush support Hexagon: Provide basic implementation and/or stubs for I/O routines. Hexagon: Add user access functions Hexagon: Add locking types and functions Hexagon: Add SMP support Hexagon: Provide basic debugging and system trap support. Hexagon: Add ptrace support Hexagon: Add time and timer functions Hexagon: Add interrupts ...

Add extra arch overrides to asm-generic/checksum.h

2011-11-01T14:34:21Z

There are plausible reasons for architectures to provide their own versions of csum_partial_copy_nocheck and csum_tcpudp_magic. By protecting these, the architecture can still re-use the asm-generic checksum.h, instead of copying it.

treewide: use printf not attribute__((format(printf,...)))

2011-11-01T00:30:54Z

Standardize the style for compiler based printf format verification. Standardized the location of __printf too. Done via script and a little typing. $ grep -rPl --include=*.[ch] -w "__attribute__" * | \ grep -vP "^(tools|scripts|include/linux/compiler-gcc.h)" | \ xargs perl -n -i -e 'local $/; while (<>) { s/\b__attribute__\s*$\s*\(\s*format\s*\(\s*printf\s*,\s*(.+)\s*,\s*(.+)\s*$\s*\)\s*\)/__printf($1, $2)/g ; print; }' [akpm@linux-foundation.org: revert arch bits] Signed-off-by: Joe Perches Cc: "Kirill A.

include/asm-generic/page.h: calculate virt_to_page and page_to_virt via predefined macro

2011-11-01T00:30:48Z

On NOMMU architectures, if physical memory doesn't start from 0, ARCH_PFN_OFFSET is defined to generate page index in mem_map array. Because virtual address is equal to physical address, PAGE_OFFSET is always 0. virt_to_page and page_to_virt should not index page by PAGE_OFFSET directly.

dma-mapping: fix sync_single_range_* DMA debugging

2011-11-01T00:30:44Z

Commit 5fd75a7850b5 (dma-mapping: remove unnecessary sync_single_range_* in dma_map_ops) unified not only the dma_map_ops but also the corresponding debug_dma_sync_* calls. This led to spurious WARN()ings like the following because the DMA debug code was no longer able to detect the DMA buffer base address without the separate offset parameter: WARNING: at lib/dma-debug.c:911 check_sync+0xce/0x446() firewire_ohci 0000:04:00.0: DMA-API: device driver tries to sync DMA memory it has not allocated [device address=0x00000000cedaa400] [size=1024 bytes] Call Trace: ... [] check_sync+0xce/0x446 [] debug_dma_sync_single_for_device+0x39/0x3b [] ohci_queue_iso+0x4f3/0x77d [firewire_ohci] ... To fix this, unshare the sync_single_* and sync_single_range_* implementations so that we are able to call the correct debug_dma_sync_* functions.
