mm: don't include asm/pgtable.h if linux/mm.h is already included Patch series "mm: consolidate definitions of page table accessors", v2. The low level page table accessors (pXY_index(), pXY_offset()) are duplicated across all architectures and sometimes more than once. For instance, we have 31 definition of pgd_offset() for 25 supported architectures. Most of these definitions are actually identical and typically it boils down to, e.g. static inline unsigned long pmd_index(unsigned long address) { return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1); } static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address) { return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address); } These definitions can be shared among 90% of the arches provided XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined. For architectures that really need a custom version there is always possibility to override the generic version with the usual ifdefs magic. These patches introduce include/linux/pgtable.h that replaces include/asm-generic/pgtable.h and add the definitions of the page table accessors to the new header. This patch (of 12): The linux/mm.h header includes <asm/pgtable.h> to allow inlining of the functions involving page table manipulations, e.g. pte_alloc() and pmd_alloc(). So, there is no point to explicitly include <asm/pgtable.h> in the files that include <linux/mm.h>. The include statements in such cases are remove with a simple loop: for f in $(git grep -l "include <linux/mm.h>") ; do sed -i -e '/include <asm\/pgtable.h>/ d' $f done Signed-off-by: Mike Rapoport <rppt@linux.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Cain <bcain@codeaurora.org> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Chris Zankel <chris@zankel.net> Cc: "David S.

audit: define AUDIT_ARCH_OPENRISC When using audit on OpenRISC, an audit arch is needed. This defines it and fixes a compile-time bug uncovered in linux-next, likely from a cut/paste from an arch with 64/32-bit modes that defined arch_arch(): arch/openrisc/kernel/ptrace.c:190:2: error: implicit declaration of function 'audit_arch' This replaces it with the newly defined AUDIT_ARCH_OPENRISC, since it is only 32-bit, and currently only operates in big-endian mode.

openrisc: sanitize use of orig_gpr11 The pt_regs struct had both a 'syscallno' field and an 'orig_gpr11' field and it wasn't really clear how these were supposed to be used. This patch removes the syscallno field altogether and makes orig_gpr11 work more like other architectures: keep track of syscall number in progress or hold -1 for non-syscall exceptions.

OpenRISC: PTrace This patch implements minimal PTrace support. The pt_regs structure is not exported to userspace for OpenRISC; rather, the GETREGSET mechanism is intended to be used and the registers, as such, exported in the core dump format which is ABI stable. This is in line with what is intended for new architectures as of 2.6.34 and has the advantage of permitting the layout of the registers on the kernel stack (as per pt_regs) to be freely modified.
