Linus,

please pull the latest smp-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git smp-urgent-for-linus

up to:  bebd024e4815 ("x86/smp: Enforce CONFIG_HOTPLUG_CPU when SMP=y")

Two SMT/hotplug related fixes:

 - Prevent crash when HOTPLUG_CPU is disabled and the CPU bringup
   aborts. This is triggered with the 'nosmt' command line option, but can
   happen by any abort condition. As the real unplug code is not compiled
   in, prevent the fail by keeping the CPU in zombie state.

 - Enforce HOTPLUG_CPU for SMP on x86 to avoid the above situation
   completely. With 'nosmt' being a popular option it's required to unplug
   the half brought up sibling CPUs (due to the MCE wreckage) completely.

Thanks,

	tglx

Linus,

please pull the latest x86-urgent-for-linus git tree from:

up to:  f560bd19d2fe ("x86/realmode: Make set_real_mode_mem() static inline")

A pile of x86 updates:

 - Prevent exceeding he valid physical address space in the /dev/mem limit
   checks.

 - Move all header content inside the header guard to prevent compile
   failures.

 - Fix the bogus __percpu annotation in this_cpu_has() which makes sparse
   very noisy.

 - Disable switch jump tables completely when retpolines are enabled.

 - Prevent leaking the trampoline address.

Thanks,

	tglx

Linus,

please pull the latest perf-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-urgent-for-linus

up to:  22261fdf68f2 ("Merge tag 'perf-urgent-for-mingo-5.1-20190329' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent")

Perf tooling related fixes:

   Core libraries:
      - Fix max perf_event_attr.precise_ip detection.
      - Fix parser error for uncore event alias
      - Fixup ordering of kernel maps after obtaining the main kernel map address.
    
   Intel PT:
      - Fix TSC slip where A TSC packet can slip past MTC packets so that the
        timestamp appears to go backwards.
      - Fixes for exported-sql-viewer GUI conversion to python3.
    
   ARM coresight:
      - Fix the build by adding a missing case value for enumeration value introduced
        in newer library, that now is the required one.
    
   tool headers:
      - Syncronize kernel headers with the kernel, getting new io_uring and
        pidfd_send_signal syscalls so that 'perf trace' can handle them.


Thanks,

	tglx

Linus,

please pull the latest core-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git core-urgent-for-linus

up to:  7dd476171149 ("watchdog: Respect watchdog cpumask on CPU hotplug")

A small set of core updates:

 - Make the watchdog respect the selected CPU mask again. That was broken
   by the rework of the watchdog thread management and caused inconsistent
   state and NMI watchdog being unstoppable.

 - Ensure that the objtool build can find the libelf location.

 - Remove dead kcore stub code

Thanks,

	tglx

Linus,

please pull the latest core-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git core-urgent-for-linus

Two small fixes:

 - Move the large objtool_file struct off the stack so objtool works in
   setups with a tight stack limit.

 - Make a few variables static in the watchdog core code.

Thanks,

	tglx
