2012-09-19nbd: do not close BlockDriverState in nbd_export_closePaolo Bonzini

2012-09-15Remove unused CONFIG_TCG_PASS_AREG0 and dead codeBlue Swirl
Now that CONFIG_TCG_PASS_AREG0 is enabled for all targets, remove dead code and support for !CONFIG_TCG_PASS_AREG0 case. Remove dyngen-exec.h and all references to it.

2012-09-15configure: properly check if -lrt and -lm is neededNatanael Copa
Fixes build against uClibc. uClibc provides 2 versions of clock_gettime(), one with realtime support and one without (this is so you can avoid linking in -lrt unless actually needed). This means that the clock_gettime() don't need -lrt. We still need it for timer_create() so we check for this function in addition. We also need check if -lm is needed for isnan(). Both -lm and -lrt are needed for libs_qga. Signed-off-by: Natanael Copa <ncopa@alpinelinux.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-09-15tcg: Fix MAX_OPC_PARAM_IARGSStefan Weil
DEF_HELPER_FLAGS_5 was added some time ago without adjusting MAX_OPC_PARAM_IARGS. Fixing the definition becomes more important as QEMU is using an increasing number of helper functions called with 5 arguments. Add also a comment to avoid future problems when DEF_HELPER_FLAGS_6 will be added.

2012-09-11xhci: update port handlingGerd Hoffmann
This patch changes the way xhci ports are linked to USBPorts. The fixed 1:1 relationship between xhci ports and USBPorts is gone. Now each USBPort represents a physical plug which has usually two xhci ports assigned: one usb2 and ond usb3 port. usb devices show up at one or the other, depending on whenever they support superspeed or not. This patch also makes the number of usb2 and usb3 ports runtime configurable by adding 'p2' and 'p3' properties. It is allowed to have different numbers of usb2 and usb3 ports. Specifying p2=4,p3=2 will give you an xhci adapter which supports all speeds on physical ports 1+2 and usb2 only on ports 3+4.
2012-09-11xhci: update register layoutGerd Hoffmann
Change the register layout to be a bit more sparse and also not depend on the number of ports. Useful when for making the number of ports runtime-configurable.
