In other words, the noerror behaviour would apply to\n the next system call where we had to reschedule or deliver a signal,\n which is not necessarily the current system call.\n\n* 32-bit wasn\u0027t doing the call to ptrace_notify in the syscall exit\n path when the _TIF_SINGLESTEP bit was set.\n\n* _TIF_RESTOREALL was in both _TIF_USER_WORK_MASK and\n _TIF_PERSYSCALL_MASK, which is odd since _TIF_RESTOREALL is only set\n by system calls. I took it out of _TIF_USER_WORK_MASK.\n\n* On 64-bit, _TIF_RESTOREALL wasn\u0027t causing the non-volatile registers\n to be restored (unless perhaps a signal was delivered or the syscall\n was traced or single-stepped). Thus the non-volatile registers\n weren\u0027t restored on exit from a signal handler. We probably got\n away with it mostly because signal handlers written in C wouldn\u0027t\n alter the non-volatile registers.\n\n* On 32-bit I simplified the code and made it more like 64-bit by\n making the syscall exit path jump to ret_from_except to handle\n preemption and signal delivery.\n\n* 32-bit was calling do_signal unnecessarily when _TIF_RESTOREALL was\n set - but I think because of that 32-bit was actually restoring the\n non-volatile registers on exit from a signal handler.\n\n* I changed the order of enabling interrupts and saving the\n non-volatile registers before calling do_syscall_trace_leave; now we\n enable interrupts first.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n" }, { "commit": "c05b47704570b015134522c36142cd17bd48640a", "tree": "11080365ff881392954d0f26f57dffbcbd47f984", "parents": [ "3af1efe8a301f5b1c813f5f761cb1e10d6175605" ], "author": { "name": "Linus Torvalds", "email": "torvalds@quad.osdl.org", "time": "Sat Mar 04 15:00:45 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@quad.osdl.org", "time": "Sat Mar 04 15:00:45 2006 -0800" }, "message": "ppc64: make sure to align stack pointer to 16 bytes at boot\n\nyaboot is scrogged and calls us with an invalid stack alignment,\nit seems.\n\nThanks to David Woodhouse to pointing me to the problem.\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "ab1b55e21f6977e420341727e9f4a50691057b5e", "tree": "f2b6c25bc8bd40db6b5dda217dc3c29a4ce06127", "parents": [ "141aa59b5347a4a021e37cfbc2258df9af9392f8" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Fri Mar 03 10:35:40 2006 +1100" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Fri Mar 03 22:01:05 2006 +1100" }, "message": "[PATCH] powerpc: incorrect rmo_top handling in prom_init\n\nOn Thu, 2006-03-02 at 19:55 +0100, Olaf Hering wrote:\n\n\u003e My iBook1 has 2 memory regions in reg.
