Hi Linus,

Here is the arm64 queue for 4.3. There's quite a lot here and the
diffstat looks pretty alarming at first glance, so let me walk you
through it:

  - There are a bunch of new arm64 features and these are summarised in
    the tag (see below).

  - One of these features (LSE) involves a pretty hefty rework of our
    atomic operations, which interacts badly with the
    atomic_{or,xor,and} rework from PeterZ in tip. To solve this, tglx
    made a stable branch (tip/locking/arch-atomic) which is included
    here and accounts for most of the surprising diffstat (it touches
    all users of atomic_{set,clear}_mask). You've already pulled this
    from tip.

  - We move our PSCI (a firmware interface for CPU power management)
    implementation out into drivers/firmware/ so that it can be shared
    with arch/arm/, rather than each architecture having a carbon copy
    of the code. This was merged as a separate branch so that RMK can
    include the changes in his tree too and subsequently move arch/arm/
    over to the common code (again, you've already pulled this).

  - There is a single patch to drivers/of/fdt.c, but that has been
    Acked-by Rob and is included here due to a dependency from the
    memblock linear-mapping restriction change.

Note that there is a conflict in arch/arm64/include/asm/barrier.h
between 76695af20c01 ("locking, arch: use WRITE_ONCE()/READ_ONCE() in
smp_store_release()/smp_load_acquire()") and 4b3dc9679cf7 ("arm64: force
CONFIG_SMP=y and remove redundant #ifdefs"). The correct resolution is
to take the version here (i.e. remove the #ifndef CONFIG_SMP block
altogether).

Please pull.

Thanks,

Will

  arm64: flush FP/SIMD state correctly after execve() (2015-08-27 09:55:26 +0100)

----------------------------------------------------------------
arm64 updates for 4.3:

- Support for new architectural features introduced in ARMv8.1:
  * Privileged Access Never (PAN) to catch user pointer dereferences in
    the kernel
  * Large System Extension (LSE) for building scalable atomics and locks
    (depends on locking/arch-atomic from tip, which is included here)
  * Hardware Dirty Bit Management (DBM) for updating clean PTEs
    automatically

- Move our PSCI implementation out into drivers/firmware/, where it can
  be shared with arch/arm/. RMK has also pulled this component branch
  and has additional patches moving arch/arm/ over. MAINTAINERS is
  updated accordingly.

- Better BUG implementation based on the BRK instruction for trapping

- Leaf TLB invalidation for unmapping user pages

- Support for PROBE_ONLY PCI configurations

- Various cleanups and non-critical fixes, including:
  * Always flush FP/SIMD state over exec()
  * Restrict memblock additions based on range of linear mapping
  * Ensure *(LIST_POISON) generates a fatal fault
  * Context-tracking syscall return no longer corrupts return value when
    not forced on.
  * Alternatives patching synchronisation/stability improvements
  * Signed sub-word cmpxchg compare fix (tickled by HAVE_CMPXCHG_LOCAL)
  * Force SMP=y
  * Hide direct DCC access from userspace
  * Fix EFI stub memory allocation when DRAM starts at 0x0

Doesn't this make sense only if DCC is enabled for ARM64?  These
patches are not part of your patchset:

[v5] ARM64: TTY: hvc_dcc: Add support for ARM64 dcc
[v3] hvc_dcc: don't ignore errors during initialization

Those patches should go via the usual route for tty changes (i.e. Greg).
I merged the arm64 change here because it (a) makes sense as a standalone
patch and (b) is a dependency for your other stuff.

Greg,

Any chance these patches can get into 4.3-rc1?

My tty/serial tree is long closed and has been merged with Linus last
week.  And, I don't even see these in my queue, as I don't even know if
they were sent to me.

If you want them in, please resend, but note that it will have to wait
for 4.4-rc1.

thanks,
