It doesn\u0027t use the mmu_gather\nstuff anymore. Instead, we use the lazy mmu hooks that were added by the\nparavirt code. They have the nice property that the enter/leave lazy mmu\nmode pair is always fully contained by the PTE lock for a given range\nof PTEs. Thus we can guarantee that all batches are flushed on a given\nCPU before it drops that lock.\n\nWe also generalize batching for any PTE update that require a flush.\n\nBatching is now enabled on a CPU by arch_enter_lazy_mmu_mode() and\ndisabled by arch_leave_lazy_mmu_mode(). The code epects that this is\nalways contained within a PTE lock section so no preemption can happen\nand no PTE insertion in that range from another CPU. When batching\nis enabled on a CPU, every PTE updates that need a hash flush will\nuse the batch for that flush.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "62c4f0a2d5a188f73a94f2cb8ea0dba3e7cf0a7f", "tree": "e85ca2d0dd43f90dccf758338764c3caa55f333f", "parents": [ "089f26d5e31b7bf42a9a8fefec08b30cd27f4b0e" ], "author": { "name": "David Woodhouse", "email": "dwmw2@infradead.org", "time": "Wed Apr 26 12:56:16 2006 +0100" }, "committer": { "name": "David Woodhouse", "email": "dwmw2@infradead.org", "time": "Wed Apr 26 12:56:16 2006 +0100" }, "message": "Don\u0027t include linux/config.h from anywhere else in include/\n\nSigned-off-by: David Woodhouse \u003cdwmw2@infradead.org\u003e\n" }, { "commit": "88ced0314938814e1772b4d0d7ab20c52e4472b6", "tree": "3e06de882c0bf5706ee7a8994e06eb8c9ed3feca", "parents": [ "e1333803c3a8fb167ba67ffc5540dbb53fa7deb3" ], "author": { "name": "Arnd Bergmann", "email": "arnd@arndb.de", "time": "Fri Dec 16 22:43:46 2005 +0100" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Mon Jan 09 15:13:08 2006 +1100" }, "message": "[PATCH] powerpc: sanitize header files for user space includes\n\ninclude/asm-ppc/ had #ifdef __KERNEL__ in all header files that\nare not meant for use by user space, include/asm-powerpc does\nnot have this yet.\n\nThis patch gets us a lot closer there.
