Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next
Pull sparc updates from David Miller: - Rework the sparc32 page tables so that READ_ONCE(*pmd), as done by generic code, operates on a word sized element. From Will Deacon. - Some scnprintf() conversions, from Chen Zhou. - A pin_user_pages() conversion from John Hubbard. - Several 32-bit ptrace register handling fixes and such from Al Viro. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next: fix a braino in "sparc32: fix register window handling in genregs32_[gs]et()" sparc32: mm: Only call ctor()/dtor() functions for first and last user sparc32: mm: Disable SPLIT_PTLOCK_CPUS sparc32: mm: Don't try to free page-table pages if ctor() fails sparc32: register memory occupied by kernel as memblock.memory sparc: remove unused header file nfs_fs.h sparc32: fix register window handling in genregs32_[gs]et() sparc64: fix misuses of access_process_vm() in genregs32_[sg]et() oradax: convert get_user_pages() --> pin_user_pages() sparc: use scnprintf() in show_pciobppath_attr() in vio.c sparc: use scnprintf() in show_pciobppath_attr() in pci.c tty: vcc: Fix error return code in vcc_probe() sparc32: mm: Reduce allocation size for PMD and PTE tables sparc32: mm: Change pgtable_t type to pte_t * instead of struct page * sparc32: mm: Restructure sparc32 MMU page-table layout sparc32: mm: Fix argument checking in __srmmu_get_nocache() sparc64: Replace zero-length array with flexible-array sparc: mm: return true,false in kern_addr_valid()
