2017-09-06target/i386: Use generic DISAS_* enumeratorsRichard Henderson
This target is not sophisticated in its use of cleanups at the end of the translation loop. For the most part, any condition that exits the TB is dealt with by emitting the exiting opcode right then and there. Therefore the only is_jmp indicator that is needed is DISAS_NORETURN. For two stack segment modifying cases, we have not yet exited the TB (therefore DISAS_NORETURN feels wrong), but intend to exit. The caller of gen_movl_seg_T0 currently checks for any non-zero value, therefore DISAS_TOO_MANY seems acceptable for that usage. Reviewed-by: Emilio G.

2017-09-05virtfs: error out gracefully when mandatory suboptions are missingGreg Kurz
We internally convert -virtfs to -fsdev/-device. If the user doesn't provide the path or security_model suboptions, and the fsdev backend requires them, we hit an assertion when populating the internal -fsdev option: util/qemu-option.c:547: opt_set: Assertion `opt->str' failed. Aborted (core dumped) Let's test the suboption presence on the command line before trying to set it in the internal -fsdev option, and let the backend code error out gracefully (ie, like it already does when the user passes -fsdev on the command line).

2017-09-059pfs: local: clarify fchmodat_nofollow() implementationGreg Kurz
Since fchmodat(2) on Linux doesn't support AT_SYMLINK_NOFOLLOW, we have to implement it using workarounds. There are two different ways, depending on whether the system supports O_PATH or not. In the case O_PATH is supported, we rely on the behavhior of openat(2) when passing O_NOFOLLOW | O_PATH and the file is a symbolic link. Even if openat_file() already adds O_NOFOLLOW to the flags, this patch makes it explicit that we need both creation flags to obtain the expected behavior. This is only cleanup, no functional change.

The non-blocking connect mechanism is obsolete, and it doesn't work well in inet connection, because it will call getaddrinfo first and getaddrinfo will blocks on DNS lookups. Since commit e65c67e4 & d984464e, the non-blocking connect of migration goes through QIOChannel in a different manner(using a thread), and nobody use this old non-blocking connect anymore. Any newly written code which needs a non-blocking connect should use the QIOChannel code, so we can drop NonBlockingConnectHandler as a concept entirely. Suggested-by: Daniel P.

2017-09-04apb: add busA qdev property to PBM PCI bridgeMark Cave-Ayland
As future sun4u PCI topologies place the ebus containing the in-built devices behind a PCI bridge, add a busA property to the PBM PCI bridge that is then used to allow IO accesses by default. This allows early fw_cfg/NVRAM/serial access to occur even before OpenBIOS has had a chance to configure the PCI bridges. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

2017-09-04apb: fix up PCI bus nomenclatureMark Cave-Ayland
Rather than referring to the PCI busses as bus2 and bus3, refer to them as busA and busB as per the documentation. Also replace the long bus names with the shorter pciA and pciB aliases (to make it easier to attach additional devices to either from the command line).
