acpi/nfit: Update nfit driver to comply with ACPI 6.1
ACPI 6.1, Table 5-133, updates NVDIMM Control Region Structure
as follows.
- Valid Fields, Manufacturing Location, and Manufacturing Date
are added from reserved range. No change in the structure size.
- IDs (SPD values) are stored as arrays of bytes (i.e. big-endian
format). The spec clarifies that they need to be represented
as arrays of bytes as well.
This patch makes the following changes to support this update.
- Change the NFIT driver to show SPD ID values in big-endian
format.
- Change sprintf format to use "0x" instead of "#" since "%#02x"
does not prepend '0'.

ACPICA: Namespace: Reorder \_SB._INI to make sure it is evaluated before _REG evaluations
ACPICA commit
f005ee6b90d152c1f499efcca6b771a93903cb55
This patch splits \_SB._INI evaluation from device initialization code, so
that it can be performed before PCI_Config _REG evaluations. This is
required for the device enumeration process. Some named objects are
initialized in \_SB._INI and PCI_Config _REG evaluations may use
uninitialized named objects because of the order issue.
This must be fixed before fixing ECDT order issue. There are existing
tables allowing ECDT EC to be used for the entire device enumeration
process, but the enabling of ECDT EC is done in \_SB._INI. Thus \_SB._INI
must be the first control method evaluated in the device enumeration
process. Normally, the order should be automatically ensured by the device
enumeration process itself (for example, PCI_Config _REGs are evaluated by
the PCI bus driver when the driver is probed by the enumeration process),
but since the process is split on Linux (partially done in Linux, partially
done in ACPICA), we need to ensure this with special logics in order to be
regression safe. Lv Zheng.

ACPICA commit

Current code flow cannot ensure _REG association can happen after the

about to run to fix this issue.
This issue is detected when acpi_ev_initialize_region() is invoked during
the table loading. And this is one of the most important the root cause why
ACPICA table loading is split into 2 load passes. Lv Zheng.

Convert straggling drivers to new six-argument get_user_pages()
Commit
d4edcf0d5695 ("mm/gup: Switch all callers of get_user_pages() to

where they no longer pass in the thread and mm pointer. But since then

Make CONFIG_FHANDLE default y
Newer Fedora and OpenSUSE didn't boot with my standard configuration.
It took me some time to figure out why, in fact I had to write a script
to try different config options systematically.
The problem is that something (systemd) in dracut depends on
CONFIG_FHANDLE, which adds open by file handle syscalls.
While it is set in defconfigs it is very easy to miss when updating
older configs because it is not default y.
Make it default y and also depend on EXPERT, as dracut use is likely

mm/rmap: batched invalidations should use existing api

mechanism for shootdown. However, it does wrong accounting of
interrupts (e.g., inc_irq_stat is called for local invalidations),
trace-points (e.g., TLB_REMOTE_SHOOTDOWN for local invalidations) and
may break some platforms as it bypasses the invalidation mechanisms of

stmmac: fix MDIO settings
Initially the phy_bus_name was added to manipulate the
driver name but it was recently just used to manage the
fixed-link and then to take some decision at run-time.
So the patch uses the is_pseudo_fixed_link and removes
the phy_bus_name variable not necessary anymore.
The driver can manage the mdio registration by using phy-handle,
dwmac-mdio and own parameter e.g. snps,phy-addr.
This patch takes care about all these possible configurations
and fixes the mdio registration in case of there is a real
transceiver or a switch (that needs to be managed by using
fixed-link).

Same can be triggered with PROVE_RCU (+ PROVE_RCU_REPEATEDLY) enabled
from tun_attach_filter() when user space calls ioctl(tun_fd, TUN{ATTACH,
DETACH}FILTER, ...) for adding/removing a BPF filter on tap devices.
Since the fix in
f91ff5b9ff52 ("net: sk_{detach|attach}_filter() rcu
fixes") sk_attach_filter()/sk_detach_filter() now dereferences the
filter with rcu_dereference_protected(), checking whether socket lock
is held in control path.
Since its introduction in
994051625981 ("tun: socket filter support"),
tap filters are managed under RTNL lock from __tun_chr_ioctl(). Thus the
sock_owned_by_user(sk) doesn't apply in this specific case and therefore
triggers the false positive.
Extend the BPF API with __sk_attach_filter()/__sk_detach_filter() pair
that is used by tap filters and pass in lockdep_rtnl_is_held() for the
rcu_dereference_protected() checks instead.

ALSA: timer: Use mod_timer() for rearming the system timer
ALSA system timer backend stops the timer via del_timer() without sync
and leaves del_timer_sync() at the close instead. This is because of
the restriction by the design of ALSA timer: namely, the stop callback
may be called from the timer handler, and calling the sync shall lead
to a hangup. However, this also triggers a kernel BUG() when the
timer is rearmed immediately after stopping without sync:
kernel BUG at kernel/time/timer.c:966!
Call Trace:
<IRQ>
[<
ffffffff8239c94e>] snd_timer_s_start+0x13e/0x1a0

....
It's the place where add_timer() checks the pending timer. It's clear
that this may happen after the immediate restart without sync in our
cases.
So, the workaround here is just to use mod_timer() instead of
add_timer(). This looks like a band-aid fix, but it's a right move,
as snd_timer_interrupt() takes care of the continuous rearm of timer.

Tushar fixes an issue which was introduced with an earlier commit, where
hardware register RAR0 default MAC address does not get set properly.
Alex fixes two issues, first being the VXLAN port number should be stored
in network order instead of in host order. The second fix corrects the ATR
code to handle IPv6 extension headers. The issue was ATR code was assuming
that it would be able to use tcp_hdr for every TCP frame that came through,
but that is not the case, which resulted in bad filters being setup.
Mark fixes a use of usleep_range() to udelay() in the case where a lock
is being held.
Stefan fixes the offline self tests where ndo_stop() should be used instead
of ndo_close(), which causes IFF_UP to be cleared and interface routes get
removed.
Emil fixes the error case where we need to return an error when a MAC
address change is rejected by the PF. This helps prevent the user from

Merge branch 'libnvdimm-for-next' of git://git./linux/kernel/git/nvdimm/nvdimm
Pull nvdimm mcsafe_memcpy use from Dan Williams:
"Now that mcsafe_memcpy() has landed, and the return value was been
clarified in commit
cbf8b5a2b649 ("x86/mm, x86/mce: Fix return
type/value for memcpy_mcsafe()"), let's hook up its primary usage in
the pmem driver.
The compilation problems from the initial posting have been fixed,
this has appeared in a -next release with no reported issues, and it
picked up an ack from Ingo. There is no pressing need to merge this
in 4.6- rc2. However, if we wait until 4.7 the new memcpy_mcsafe()
capability will ship without a user in 4.6-final"

parisc: Fix and enable seccomp filter support
The seccomp filter support requires careful handling of task registers. This
includes reloading of the return value (%r28) and proper syscall exit if
secure_computing() returned -1.
Additionally we need to sign-extend the syscall number from signed 32bit to
signed 64bit in do_syscall_trace_enter() since the ptrace interface only allows
storing 32bit values in compat mode.
