Merge branch 'upstream-merge'
* upstream-merge: (88 commits) Add ability to force enable/disable of tools build Add ability to disable build of all targets RTC: Remove the current_tm field RTC: Get and set time without going through s->current_tm RTC: Do not fire timer periodically to catch next alarm RTC: Add divider reset support RTC: Update the RTC clock only when reading it vmstate: add VMSTATE_TIMER_V RTC: Update interrupt state when interrupts are masked/unmasked RTC: introduce RTC_CLOCK_RATE RTC: Rename rtc_timer_update RTC: Remove the logic to update time format when DM bit changed socket: don't attempt to reconnect a TCP socket in server mode use --libexecdir instead of ignoring it first and reinventing it later hw/mcf5206: Fix buffer overflow for MBAR read / write target-arm: Fix potential buffer overflow hw/wm8750: Fix potential buffer overflow kvm: i386: Add classic PCI device assignment kvm: i386: Add services required for PCI device assignment kvm: Introduce kvm_has_intx_set_mask ...
