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.

Since cpumask_t is currently u_int on all platforms this should just be a cosmetic change. 2010-11-09T20:00:23Z John Baldwin jhb@FreeBSD.org 2010-11-09T20:00:23Z urn:sha1:a26ed28729efb7381732e565a58a4ac453e4c7c6 Add a new ipi_cpu() function to the MI IPI API that can be used to send an IPI to a specific CPU by its cpuid. Replace calls to ipi_selected() that constructed a mask for a single CPU with calls to ipi_cpu() instead. 2010-11-03T21:21:12Z Konstantin Belousov kib@FreeBSD.org 2010-11-03T21:21:12Z urn:sha1:e974cac769ba6803e6d1a39345cb27e3b5e836be Reorganize syscall entry and leave handling. Implement ptrace_lwpinfo pl_flags PL_FLAG_SCE, PL_FLAG_SCX and PL_FLAG_EXEC. The i386, amd64, sparc64, sun4v, powerpc and ia64 syscall()s are changed to use syscallenter()/syscallret(). MIPS and arm are not converted and use the mostly unchanged syscall() implementation. MFC r208514: Change ia64' struct syscall_args definition so that args is a pointer to the arguments array instead of array itself. MFC r208566: Allow to use syscallname(9) outside subr_trap.c. MFC r209258 (by rpaulo): Make DTrace syscall provider work again by including opt_kdtrace.h here. MFC r209313: Only enable kdtrace hook in the LINT on the architectures that implement it. MFC r209697: Obey sv_syscallnames bounds in syscallname(). NOTE: The KBI of the struct sysentvec is changed, new required members sv_set_syscall_retval, sv_fetch_syscall_args and sv_syscallnames are added. The sv_prepsyscall field is now ignored. Third-party modules using the struct sysentvec must be modified and recompiled, we believe that only ABI emulators are affected. No such out-of-tree modules are known. In-tree modules that are affected by the change were converted to depend on exact version of the kernel, see r214421. 2010-10-17T13:13:13Z Marius Strobl marius@FreeBSD.org 2010-10-17T13:13:13Z urn:sha1:7ce3ef94c336ca3c6210a8a32dd270034dfe211c Just use the sparc64 version of this header rather than duplicating it. 2010-10-17T12:11:42Z Marius Strobl marius@FreeBSD.org 2010-10-17T12:11:42Z urn:sha1:3f754f22ac373fdebbd685ae6529c3734a034ac5 The NetBSD Foundation has granted permission to remove clause 3 and 4 from the software.

Generally using a presz of 0 (which indeed might indicate the use of bogus parameters for DMA tag creation) is not fatal, it just means that no additional DVMA space will be preallocated. 2010-09-15T18:09:16Z Marius Strobl marius@FreeBSD.org 2010-09-15T18:09:16Z urn:sha1:5a8044f8933d806edbcb95eb19c5cca4c343bf49 Allocate proper amount of memory for interrupt names on sparc64 and sun4v, same as done on other architectures. This removes garbage from `vmstat -ia` output.
