Serialize accesses to "struct vmspace" and document its refcounting. The underlying vm_space lock is used as a substitute to the KERNEL_LOCK() in uvm_grow() to make sure `vm_ssize' is not corrupted. ok anton@, kettenis@ |

| message |
Set %r0 to EFAULT instead of the return value from uvm_fault() when it fails and we're doing a copyin/copyout. Fixes a buf where systems calls would return EACCESS instead of EFAULT when accessing userland memory that can't be accessed. ok patrick@ |

deliver SIGSEGV rather than SIGBUS for T_PROTFLT,T_SEGNPFLT,T_STKFLT. This is a similar translation as i386, and matches the idea that SIGBUS signals refer to problems with the underlying object rather than the mapping. ok kettenis |

Only use OPAL_CONSOLE_FLUSH if the firmware implements it. Should help on POWER8 machines with older versions of OPAL. |

Decode the UDF ("permanently undefined") instruction in ddb(4)'s arm64 disassembler. The particular immediate16 format appears to be unique to this instruction. ok kettenis@ deraadt@ |
