ea5776ec47 Fix the NFSv4.0 server so that it does not support NFSv4.1 attributes.
During inspection of a packet trace, I noticed that an NFSv4.0 mount
reported that it supported attributes that are only defined for NFSv4.1.
In practice, this bug appears to be benign, since NFSv4.0 clients will
not use attributes that were added for NFSv4.1.
However, this was not correct and this patch fixes the NFSv4.0 server
so that it only supports attributes defined for NFSv4.0.
It also adds a definition for NFSv4.1 attributes that can only be set,
although it is only defined as 0 for now.
This is anticipation of the addition of support for the NFSv4.1 mode+mask
attribute soon.

bc60451a47 powerpc/powernv: Make erasing before writes optional

68cea2b106 Push down INP_WLOCK slightly in tcp_ctloutput.
The inp lock is not needed for testing the V6 flag as that flag is set
once when the inp is created and never changes.  For non-TCP socket
options the lock is immediately dropped after checking that flag.
This just pushes the lock down to only be acquired for TCP socket
options.

This isn't a hot-path, more a cosmetic cleanup I noticed while reading
the code.

3782136ff1 random(4): Restore availability tradeoff prior to r346250
As discussed in that commit message, it is a dangerous default.  But the
safe default causes enough pain on a variety of platforms that for now,
restore the prior default.

Some of this is self-induced pain we should/could do better about; for
example, programmatic CI systems and VM managers should introduce entropy
from the host for individual VM instances.  This is considered a future work
item.

On modern x86 and Power9 systems, this may be wholly unnecessary after
D19928 lands (even in the non-ideal case where early /boot/entropy is
unavailable), because they have fast hardware random sources available early
in boot.  But D19928 is not yet landed and we have a host of architectures
which do not provide fast random sources.

This change adds several tunables and diagnostic sysctls, documented
thoroughly in UPDATING and sys/dev/random/random_infra.c.

f9feb09189 Correct handling of RMRR during early enumeration stages.
On some machines, DMAR contexts must be created before all devices
under the scope of the corresponding DMAR unit are enumerated.
Current code has two problems with that:
- scope lookup returns NULL device_t, which causes to skip creating a
  context with RMRR, which is fatal for the affected device.
- calculation of the final pci dbsf address fails if any bridge in the
  scope is not yet enumerated, because code relies on pcib_get_bus().

Make creation of contexts work either with device_t, or with DMAR PCI
scope paths.  Scope provides enough information to infer context
address, and it is directly matched against DMAR tables scopes.

When calculating bus addresses for the scope or device, use direct
pci_cfgregread(PCIR_SECBUS_1) to get the secondary bus number, instead
of pcib_get_bus().

The issue was observed on HP Gen servers, where iLO PCI devices are
located behind south bridge switch.  Turning on translation without
satisfying RMRR requests caused iLO to mostly hang, up to the level of
being unusable to control the server.

While there, remove hw.dmar.dmar_match_verbose tunable, and make the
normal logging under bootverbose useful and sufficient to diagnose
DRHD and RMRR parsing and matching.

We must count the number of entries in the table and release the lock during

pfr_set_tflags() will check if the table and entries exist.

itself up, but leave the log file in $TMPDIR for post-mortem analysis of

77f9408865 Only set up the interrupts that will actually be used in arm generic_timer.
The code previously set up interrupt handlers for all the interrupt
resources available, including for timers that are not in use.  That could
lead to interrupt storms.  For example, if boot firmware enabled the virtual
timer but the kernel is using the physical timer, it could get flooded with
interrupts on the virtual timer which it cannot shut off.  By only setting
up an interrupt handler for the hardware that will actually be used, any
interrupts from other timer units will remain masked in the interrupt
controller.

This is useful for arm (possibly other arches too) where we want to have
a GENERIC kernel that only include files for the different SoC. Since
multiple SoCs/Board needs the same device we would need to do either :

    Include the device in a generic file
    Include the device in each file that really needs it

Option 1 works but if someone wants to create a specific kernel config
(which isn't uncommon for embedded system), he will need to add a lots
of nodevice to it.

Option 2 also works but produce a lots of warnings.

fdfe249b63 Fix initial x87 state after r345562.
After the referenced commit, we did not set x87 and sse valid bits in
the xstate_bv bitmask for initial fpu state (stored in memory), when
using XSAVE.

The state is loaded into FPU register file to initialize the process
FPU state, and since both bits were clear, the default x87 and SSE
states were loaded.  By chance, FreeBSD ABI SSE2 state is same as FPU
initial state, so the bug is not visible for 64bit processes.  But on
i386, the precision control should be set to double (53bit mantissa),
instead of the default double extended (64bit mantissa). For 32bit
processes on amd64, kernel reloads control word with the right mask,
which only left native i386 and amd64 native but using x87 as
affected.

Fix it by setting minimal required xstate_bv mask.
