It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here. Other process execution related bits\n could perhaps go here from asm/processor.h.\n\n (4) asm/cmpxchg.h\n\n Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n frequently used by atomic_xchg() and atomic_cmpxchg().\n\n (5) asm/bug.h\n\n Move die() and related bits.\n\n (6) asm/auxvec.h\n\n Move AT_VECTOR_SIZE_ARCH here.\n\n Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that.

This helper was wrong and could indicate that a valid\npointer returned to userspace was a failed syscall. The fix is to fix the\nlayering foolishness. We now pass audit_syscall_exit a struct pt_reg and it\nin turns calls back into arch code to collect the return value and to\ndetermine if the syscall was a success or failure. We also define a generic\nis_syscall_success() macro which determines success/failure based on if the\nvalue is \u003c -MAX_ERRNO. This works for arches like x86 which do not use a\nseparate mechanism to indicate syscall failure.\n\nWe make both the is_syscall_success() and regs_return_value() static inlines\ninstead of macros. The reason is because the audit function must take a void*\nfor the regs. (uml calls theirs struct uml_pt_regs instead of just struct\npt_regs so audit_syscall_exit can\u0027t take a struct pt_regs). Since the audit\nfunction takes a void* we need to use static inlines to cast it back to the\narch correct structure to dereference it.\n\nThe other major change is that on some arches, like ia64, MIPS and ppc, we\nchange regs_return_value() to give us the negative value on syscall failure.\nTHE only other user of this macro, kretprobe_example.c, won\u0027t notice and it\nmakes the value signed consistently for the audit functions across all archs.\n\nIn arch/sh/kernel/ptrace_64.c I see that we were using regs[9] in the old\naudit code as the return value. But the ptrace_64.h code defined the macro\nregs_return_value() as regs[3]. I have no idea which one is correct, but this\npatch now uses the regs_return_value() function, so it now uses regs[3].\n\nFor powerpc we previously used regs-\u003eresult but now use the\nregs_return_value() function which uses regs-\u003egprs[3]. regs-\u003egprs[3] is\nalways positive so the regs_return_value(), much like ia64 makes it negative\nbefore calling the audit code when appropriate.\n\nSigned-off-by: Eric Paris \u003ceparis@redhat.com\u003e\nAcked-by: H.

The whole guarantees\nthat we only update the dyntick mode on irq exit if we actually\ninterrupted the dyntick idle mode, and that we enter in RCU extended\nquiescent state from idle loop entry only.\n\nSplit this function into:\n\n- tick_nohz_idle_enter(), which sets ts-\u003einidle to 1, enters\ndynticks idle mode unconditionally if it can, and enters into RCU\nextended quiescent state.\n\n- tick_nohz_irq_exit() which only updates the dynticks idle mode\nwhen ts-\u003einidle is set (ie: if tick_nohz_idle_enter() has been called).\n\nTo maintain symmetry, tick_nohz_restart_sched_tick() has been renamed\ninto tick_nohz_idle_exit().\n\nThis simplifies the code and micro-optimize the irq exit path (no need\nfor local_irq_save there). This also prepares for the split between\ndynticks and rcu extended quiescent state logics.
