While the following commit:

  37868fe1

 ("x86/ldt: Make modify_ldt synchronous")

added a nice comment explaining that Xen needs page-aligned
whole page chunks for guest descriptor tables, it then
nevertheless used kzalloc() on the small size path.

As I'm unaware of guarantees for kmalloc(PAGE_SIZE, ) to return
page-aligned memory blocks, I believe this needs to be switched
back to __get_free_page() (or better get_zeroed_page()).

The CONFIG_VM86 Kconfig help text is actively misleading, so fix it:

  - Don't mark it 'obsolete' in the text as we'll support the ABI as long as CPUs
    support it.

  - Qualify the part about software emulation and mention that for some apps you
    want a real vm86 mode.

  - Don't scare users away from the option, instead explain what it does.

vm86 exposes an interesting attack surface against the entry
code. Since vm86 is mostly useless anyway if mmap_min_addr != 0,
just turn it off in that case.

There are some reports that vbetool can work despite setting
mmap_min_addr to zero.  This shouldn't break that use case,
as CAP_SYS_RAWIO already overrides mmap_min_addr.

optimize_nops() is buggy in two aspects:

- It's not disabling interrupts across the modification
- It's lacking a sync_core() call

Add both.

With the addition of NVDIMM support, a question came up as to
whether NVDIMM ranges should be in the SRAT with this bit set.
I think the consensus was no because the ranges are in the NFIT
with proximity domain information there.

ACPI is not clear on the meaning of this bit in the SRAT.
If someone is setting it, we might want to ask them what they
expect to happen with it.

Right now this bit is only printed if all the ACPI debug
information is turned on.

   - Add support for using several Intel PT features (CYC, MTC packets),
     the relevant documentation was updated in:
         tools/perf/Documentation/intel-pt.txt
     briefly describing those packets, its purposes, how to configure
     them in the event config terms and relevant external documentation
     for further reading.  (Adrian Hunter)

   - Introduce support for probing at an absolute address, for user and
     kernel 'perf probe's, useful when one have the symbol maps on a
     developer machine but not on an embedded system.  (Wang Nan)

   - Add Intel BTS support, with a call-graph script to show it and PT
     in use in a GUI using 'perf script' python scripting with
     postgresql and Qt.  (Adrian Hunter)

   - Allow selecting the type of callchains per event, including
     disabling callchains in all but one entry in an event list, to save
     space, and also to ask for the callchains collected in one event to
     be used in other events.  (Kan Liang)

   - Beautify more syscall arguments in 'perf trace': (Arnaldo Carvalho
     de Melo)
       * A bunch more translate file/pathnames from pointers to strings.
       * Convert numbers to strings for the 'keyctl' syscall 'option'
         arg.
       * Add missing 'clockid' entries.

   - Introduce 'srcfile' sort key: (Andi Kleen)

       # perf record -F 10000 usleep 1
       # perf report --stdio --dsos '[kernel.vmlinux]' -s srcfile
       <SNIP>
       # Overhead  Source File
          26.49%  copy_page_64.S
           5.49%  signal.c
           0.51%  msr.h
       #

     It can be combined with other fields, for instance, experiment with
     '-s srcfile,symbol'.

     There are some oddities in some distros and with some specific
     DSOs, being investigated, so your mileage may vary.

   - Support per-event 'freq' term: (Namhyung Kim)

       $ perf record -e 'cpu/instructions,freq=1234/',cycles -c 1000 sleep 1
       $ perf evlist -F
       cpu/instructions,freq=1234/: sample_freq=1234
       cycles: sample_period=1000
       $

   - Deref sys_enter pointer args with contents from probe:vfs_getname,
     showing pathnames instead of pointers in many syscalls in 'perf
     trace'.  (Arnaldo Carvalho de Melo)

   - Stop collecting /proc/kallsyms in perf.data files, saving about
     4.5MB on a typical x86-64 system, use the the symbol resolution
     routines used in all the other tools (report, top, etc) now that we
     can ask libtraceevent to use perf's symbol resolution code.
     (Arnaldo Carvalho de Melo)

   - Allow filtering out of perf's PID via 'perf record --exclude-perf'.
     (Wang Nan)

   - 'perf trace' now supports syscall groups, like strace, i.e:

       $ trace -e file touch file

     Will expand 'file' into multiple, file related, syscalls.  More
     work needed to add extra groups for other syscall groups, and also
     to complement what was added for the 'file' group, included as a
     proof of concept.  (Arnaldo Carvalho de Melo)

   - Add lock_pi stresser to 'perf bench futex', to test the kernel code
     related to FUTEX_(UN)LOCK_PI.  (Davidlohr Bueso)

   - Let user have timestamps with per-thread recording in 'perf record'
     (Adrian Hunter)

Pull RCU updates from Ingo Molnar:
 "The main RCU changes in this cycle are:

   - the combination of tree geometry-initialization simplifications and
     OS-jitter-reduction changes to expedited grace periods.  These two
     are stacked due to the large number of conflicts that would
     otherwise result.

   - privatize smp_mb__after_unlock_lock().

     This commit moves the definition of smp_mb__after_unlock_lock() to
     kernel/rcu/tree.h, in recognition of the fact that RCU is the only
     thing using this, that nothing else is likely to use it, and that
     it is likely to go away completely.

   - documentation updates.

   - torture-test updates.

   - misc fixes"
