Kirill A. Shutemov with faultaround patchset introduced vm_ops->map_pages() for mapping easy accessible pages around fault address in hope to reduce number of minor page faults. This patchset creates infrastructure to move the FAULT_AROUND_ORDER to arch/ using Kconfig. This will enable architecture maintainers to decide on suitable FAULT_AROUND_ORDER value based on performance data for that architecture. First patch also adds FAULT_AROUND_ORDER Kconfig element for X86. Second patch list out the performance numbers for powerpc (platform pseries) and adds FAULT_AROUND_ORDER Kconfig element for powerpc. V2 Changes: Created Kconfig parameter for FAULT_AROUND_ORDER Added check in do_read_fault to handle FAULT_AROUND_ORDER value of 0 Made changes in commit messages.
