Some use of those functions were providing unitialized values to those

Tested with this simple program:

The reason is the incorrect assumption in fpu_copy(), that FNSAVE
can be executed from math-emu kernels as well.

Don't try to copy the registers, the soft state will be copied
by fork anyway, so the child task inherits the parent task's
soft math state.

With this fix applied math-emu kernels boot up fine on modern
hardware and the 'no387 nofxsr' boot options.

The reason is that in the following commit:

  b1276c48 ("x86/fpu: Initialize fpregs in fpu__init_cpu_generic()")

I failed to consider math-emu's limitation that it cannot execute the
FNINIT instruction in kernel mode.

The long term fix might be to allow math-emu to execute (certain) kernel
mode FPU instructions, but for now apply the safe (albeit somewhat ugly)
fix: initialize the emulation state explicitly without trapping out to
the FPU emulator.

Commit c48a11c7 ("netvm: propagate page->pfmemalloc to skb") added
checks for page->pfmemalloc to __skb_fill_page_desc():

        if (page->pfmemalloc && !page->mapping)
                skb->pfmemalloc = true;

It assumes page->mapping == NULL implies that page->pfmemalloc can be
trusted.  However, __delete_from_page_cache() can set set page->mapping
to NULL and leave page->index value alone.  Due to being in union, a
non-zero page->index will be interpreted as true page->pfmemalloc.

So the assumption is invalid if the networking code can see such a page.
And it seems it can.  We have encountered this with a NFS over loopback
setup when such a page is attached to a new skbuf.  There is no copying
going on in this case so the page confuses __skb_fill_page_desc which
interprets the index as pfmemalloc flag and the network stack drops
packets that have been allocated using the reserves unless they are to
be queued on sockets handling the swapping which is the case here and
that leads to hangs when the nfs client waits for a response from the
server which has been dropped and thus never arrive.

The struct page is already heavily packed so rather than finding another
hole to put it in, let's do a trick instead.  We can reuse the index
again but define it to an impossible value (-1UL).  This is the page
index so it should never see the value that large.  Replace all direct
users of page->pfmemalloc by page_is_pfmemalloc which will hide this
nastiness from unspoiled eyes.

The information will get lost if somebody wants to use page->index
obviously but that was the case before and the original code expected
that the information should be persisted somewhere else if that is
really needed (e.g.  what SLAB and SLUB do).

Meelis and Helge reported that 3a9ad0b4 ("PCI: Add pci_bus_addr_t")
caused HPMCs on A500 and hangs on rp5470.

PA-RISC does not set ARCH_DMA_ADDR_T_64BIT, even for 64-bit kernels, so
prior to 3a9ad0b4, we always used 32-bit PCI addresses.  After
3a9ad0b4, we do use 64-bit PCI addresses in 64-bit kernels, and
apparently there's some PA-RISC problem related to them.

Pull sound fixes from Takashi Iwai:
 "Here are a small collecton of sound fix patches.

  The most significant one is the disablement of newly introduced
  topology API.  Its ABI couldn't be stabilized enough, so we decided to
  delay for 4.3 in the end.  Other than that, all oneliner fixes: a
  USB-audio runtime PM fix and a couple of HD-audio quirks"

GPIOF_IN flag was lost in:
Commit 633a21d8("input: gpio_keys_polled: Add support for GPIO
descriptors").

Without this flag, legacy code path (for non-descriptor GPIO declarations)
would configure GPIO as output (0 meaning GPIOF_DIR_OUT | GPIOF_INIT_LOW).

Pull SCSI target fixes from Nicholas Bellinger:
 "This contains a v4.2-rc specific RCU module unload regression bug-fix,
  a long-standing iscsi-target bug-fix for duplicate target_xfer_tags
  during NOP processing from Alexei, and two more small REPORT_LUNs
  emulation related patches to make Solaris FC host LUN scanning happy
  from Roland.

  There is also one patch not included that allows target-core to limit
  the number of fabric driver SGLs per I/O request using residuals, that
  is currently required as a work-around for FC hosts which don't honor
  EVPD block-limits settings.  At this point, it will most likely become
  for-next material"

Commit 6dd74782 ("ARM: imx: move timer resources into a structure")
moved initialization parameters into a data structure, but neglected to set
the irq field in that data structure for non-DT boots. This causes the system
to hang if a non-DT boot is attempted.

Since commit feb44f1f (x86/xen:
Provide a "Xen PV" APIC driver to support >255 VCPUs) Xen guests need
a full APIC driver and thus should depend on X86_LOCAL_APIC.

This fixes an i386 build failure with !SMP && !CONFIG_X86_UP_APIC by
disabling Xen support in this configuration.

Users needing Xen support in a non-SMP i386 kernel will need to enable
CONFIG_X86_UP_APIC.

Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

  - Fix buildid processing done at the end of a 'perf record' session, a
    problem that happened in workloads involving lots of small short-lived
    processes.  That code was not asking the perf_session layer to order
    the events.

    Make the code more robust to handle some of the problems with such
    out-of-order events and fix 'perf record' to ask for ordered events
    on systems where we have perf_event_attr.sample_id_all.  (Adrian Hunter)
