Paolo Bonzini 8a201bd47e target-i386: fix kernel accesses with SMAP and CPL = 3 
With SMAP, implicit kernel accesses from user mode always behave as
if AC=0.  To do this, kernel mode is not anymore a separate MMU mode.
Instead, KERNEL_IDX is renamed to KSMAP_IDX and the kernel mode accessors
wrap KSMAP_IDX and KNOSMAP_IDX.

Stefan Weil 7e4e88656c cputlb: Fix regression with TCG interpreter (bug 1310324) 
Commit 0f842f8a24 replaced GETPC_EXT() which
was derived from GETPC() by GETRA_EXT() without fixing cputlb.c. A later
patch replaced GETRA_EXT() by GETRA() in exec/softmmu_template.h which
is included in cputlb.c.

The TCG interpreter failed because the values returned by GETRA() were no
longer explicitly set to 0. The redefinition of GETRA() introduced here
fixes this.

In addition, GETPC_ADJ which is also used in exec/softmmu_template.h is
set to 0. Both changes reduce the compiled code size for cputlb.c by more
than 100 bytes, so the normal TCG without interpreter also profits from
the reduced code size and slightly faster code.

Gonglei b52991537c vnc-enc-tight: Fix divide-by-zero in tight_detect_smooth_image{16,24,32} 
Spotted by Coverity:

(1) Event assignment:  Assigning: "pixels" = "0".
(2) Event cond_true:  Condition "y < h", taking true branch
(3) Event cond_false:  Condition "x < w", taking false branch
(4) Event loop_end:  Reached end of loop
(5) Event divide_by_zero:  In expression "(stats[0] + stats[1]) * 100U / pixels",
division by expression "pixels" which may be zero has undefined behavior.

Gerd Hoffmann cf864569cd vnc: refuse to set a password with VNC_AUTH_NONE 
Current code silently changes the authentication settings
in case you try to set a password without password authentication
turned on.  This is bad.  Return an error instead.

If we want allow changing auth settings at runtime this should
be done explicitly using a separate monitor command, not as
side effect of set_passwd.

Gerd Hoffmann b791c3b38c usb: add usb_pick_speed 
We can pick the usb port speed in generic code, by looking at the port
and device speed masks and looking for the fastest match.  So add a
function to do exactly that, and drop the speed setting code from
usb_desc_attach as it isn't needed any more.

This way we can set the device speed before calling port->ops->attach,
which fixes some xhci hotplug issues.

Gerd Hoffmann b88a3e01f5 usb-host: allow attaching usb3 devices to ehci 
Extend compatibility test function to also figure whenever usb3
devices can be supported on ehci.  Tweak ep0 maxpacketsize field
due to usb2 <-> usb3 difference.

Gerd Hoffmann d81d410635 usb: improve ehci/uhci test 
* Attach usb devices to the bus.
 * Check initial port status register state.
 * Flip ehci initialization bit.
 * Check port status register state again to
   see whenever device handover to ehci worked.
