* Merge MIPS platform support to 8-STABLE.Jayachandran C.2010-11-2733-558/+651
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit merges the MIPS platform changes that was now stable in -CURRENT into 8-STABLE. The MIPS changesets are too many (~400) to list here. But the changesets merged in this commit that affect other platforms are summarized below: r204635 : (changes to sys/dev/hwpmc, lib/libpmc, sys/sys/pmc.h) Add support for hwpmc(4) on the MIPS 24K, 32 bit, embedded processor. r205845: (changes to sys/modules/Makefile) Fix for building modules on mips and arm. r204031: (changes to sys/kern/link_elf_obj.c) printf fix, as part of kernel module support for MIPS. r206404: (changes to sys/arm/include/bus.h) Add BUS_SPACE_UNRESTRICTED and define it to be ~0, just like all the other platforms - for arm and mips. r206819: (changes to sys/vm/) Add VMFS_TLB_ALIGNED_SPACE option and kmem_alloc_nofault_space(), which is used to allocate kernel stack address on MIPS. r208165, r211087: (sys/kern/subr_smp.c, sys/kern/sched_ule.c) Enable ULE scheduler for MIPS, Fix for an issue in SMP when 32 cpus are enabled. r208659: (sys/{ia64/ia64,mips/mips,sun4v/sun4v}/pmap.c) Simplify the inner loop of get_pv_entry() r208794: (changes to sys/vm/) Make vm_contig_grow_cache() extern, and use it when vm_phys_alloc_contig() fails to allocate MIPS page table pages. r210327: (changes to sys/vm/) Support for MIPS page table page allocation. Add a new function 'vm_page_t vm_page_alloc_freelist(int flind, int order, int req)' to vm/vm_page.c to allocate a page from a specified freelist, and other related changes.

* MFC r212906:Edward Tomasz Napierala2010-11-011-6/+26
| | | | | | | | | | First step at adopting FreeBSD to support PSARC/2010/029. This makes acl_is_trivial_np(3) properly recognize the new trivial ACLs.

* MFC r213326: libc: Remove the i386 assembler version of strlen(3).Jilles Tjoelker2010-10-192-55/+1
| | | | | | | | | | | | | | On anything modern, the C version, which processes a word at a time, is much faster. The Intel optimization manual explicitly warns against using REP prefixes with SCAS or CMPS, which is exactly what the assembler version does. A simple test on a Phenom II showed the C version, compiled with -O2, to be about twice as fast determining the length of 100000 strings between 0 and 255 bytes long.

| | | | | | | | | | | | | | | | | strptime(3) confused July with June with the fr_FR locale. When parsing the month "juillet" (abbr "jul"), %B recognized it as "juin" (abbr "jui") because the full name of the month names is checked at the same time as the abbrevation. The new behaviour checks the full names first before checking the abbrevation names. PR: kern/141939 Submitted by: Denis Chatelain <denis@tikuts.com> Notes: svn path=/stable/8/; revision=214079

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two optimizations to MI strlen(3) inspired by David S. Miller's blog posting [1]. - Use word-sized test for unaligned pointer before working the hard way. Memory page boundary is always integral multiple of a word alignment boundary. Therefore, if we can access memory referenced by pointer p, then (p & ~word mask) must be also accessible. - Better utilization of multi-issue processor's ability of concurrency. The previous implementation utilized a formular that must be executed sequentially. However, the ~, & and - operations can actually be caculated at the same time when the operand were different and unrelated. The original Hacker's Delight formular also offered consistent performance regardless whether the input would contain characters with their highest-bit set, as it catches real nul characters only. These two optimizations has shown further improvements over the previous implementation on microbenchmarks on i386 and amd64 CPU including Pentium 4, Core Duo 2 and i7.
