      "message": "[PATCH] syscall entry/exit revamp\n\nThis cleanup patch speeds up the null syscall path on ppc64 by about 3%,\nand brings the ppc32 and ppc64 code slightly closer together.\n\nThe ppc64 code was checking current_thread_info()-\u003eflags twice in the\nsyscall exit path; once for TIF_SYSCALL_T_OR_A before disabling\ninterrupts, and then again for TIF_SIGPENDING|TIF_NEED_RESCHED etc after\ndisabling interrupts. Now we do the same as ppc32 -- check the flags\nonly once in the fast path, and re-enable interrupts if necessary in the\nptrace case.\n\nThe patch abolishes the \u0027syscall_noerror\u0027 member of struct thread_info\nand replaces it with a TIF_NOERROR bit in the flags, which is handled in\nthe slow path. This shortens the syscall entry code, which no longer\nneeds to clear syscall_noerror.\n\nThe patch adds a TIF_SAVE_NVGPRS flag which causes the syscall exit slow\npath to save the non-volatile GPRs into a signal frame. This removes the\nneed for the assembly wrappers around sys_sigsuspend(),\nsys_rt_sigsuspend(), et al which existed solely to save those registers\nin advance. It also means I don\u0027t have to add new wrappers for ppoll()\nand pselect(), which is what I was supposed to be doing when I got\ndistracted into this...\n\nFinally, it unifies the ppc64 and ppc32 methods of handling syscall exit\ndirectly into a signal handler (as required by sigsuspend et al) by\nintroducing a TIF_RESTOREALL flag which causes _all_ the registers to be\nreloaded from the pt_regs by taking the ret_from_exception path, instead\nof the normal syscall exit path which stomps on the callee-saved GPRs.\n\nIt appears to pass an LTP test run on ppc64, and passes basic testing on\nppc32 too. Brief tests of ptrace functionality with strace and gdb also\nappear OK. I wouldn\u0027t send it to Linus for 2.6.15 just yet though :)\n\nSigned-off-by: David Woodhouse \u003cdwmw2@infradead.org\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n"
