63b87fecb9 libunwind: consistently add \n to log and trace messages
Previously most messages included a newline in the string, but a few of
them were missing. Fix these and simplify by just adding the newline in
the _LIBUNWIND_LOG macro itself.

While here correct 'libuwind' typo (missing 'n').

Upstream LLVM libunwind commits r280086 and r280103.

46d7e8f428 Add powerd(8) support for several families of AMD CPUs.
Use the same logic to calculate the nominal CPU frequency from the P-state
MSRs on family 0x12, 0x15, and 0x16 CPUs as is used for family 0x10.
Family 0x14 was included in the original patch in the PR but I left that
out as the BIOS writer's guide for family 0x14 CPUs show a different layout
for the relevant MSR and include a different formulate for calculating the
frequency.

While here, simplify a few expressions and print out the family of
unsupported CPUs in hex rather than decimal.

eff8c9eb56 Various fixes for ptnet/ptnetmap (passthrough of netmap ports). In detail:
- use PCI_VENDOR and PCI_DEVICE ids from a publicly allocated range
  (thanks to RedHat)
- export memory pool information through PCI registers
- improve mechanism for configuring passthrough on different hypervisors
Code is from Vincenzo Maffione as a follow up to his GSOC work.

d9a103eacd 3746 ZRLs are racy
illumos/illumos-gate@260af64db7
260af64db7

https://www.illumos.org/issues/3746
  From the original change log:
  It was possible for a reference to be added even with the lock held, and
  for references added just after a lock release to be lost.
  This bug was also independently found and reported in wesunsolve.net
  issues 6985013 6995524.
  In zrl_add(), always use an atomic operation to update the refcount.
  The mutex in the ZRL only guarantees that wakeups occur for waiters on the
  lock. It offers no protection against concurrent updates of the refcount.
  The only refcount transition that is safe to perform without an atomic
  operation is from ZRL_LOCKED back to 0, since this can only be performed
  by the thread which has the ZRL locked.

ae1163bd55 The UFS/FFS filesystem checks directory link counts when doing
directory create and delete operations. If it ever finds a directory
with a link count less than 2, it panics. Thus, an rm -rf that
encounters a directory with a link count below 2 causes a kernel
panic. The proposed fix is to return the error EINVAL rather than
panicing. The effect is that the requested operation is not done,
but the system continues to run. At a more convenient later time,
the filesystem can be unmounted and cleaned (with fsck or journal
run). Once cleaned, the operation can be rerun to successful
completion.

This fix takes that approach. The panic message has been converted
into a uprintf(9) to provide the user with the inode number and
filesystem mount point of the offending directory and EINVAL is
returned for the operation.

The long (three year) delay in fixing this problem occurred because
the bug was misclassified when originally assigned and only this week
was found during a sweep of old unresolved bug reports.

c3c885eb65 Enable EFER_NXE properly on APs.
EFER_NXE is set in the EFER MSR by initializecpu() and must be set on all
CPUs in the system.  When PG_NX support was added to PAE on i386, the
block to enable EFER_NXE was placed in a section of initializecpu() that
only runs if 'cpu == CPU_686'.  During early boot, locore does an
initial pass to set cpu that sets it to CPU_686 on all CPUs later than
a Pentium.  Later, printcpuinfo() adjusts the 'cpu' variable on
PII and later CPUs to one of CPU_PII, CPU_PIII, or CPU_P4.  However,
printcpuinfo() is called after initializecpu() on the BSP, so the BSP
would enable EFER_NXE and pg_nx.  The APs execute initializecpu() much
later after printcpuinfo() has run.  The end result on a modern CPU was
that cpu was set to CPU_PIII when the APs invoked initializecpu(), so
they did not enable EFER_NXE.  As a result, the APs would fault when
trying to access any pages marked with PG_NX set.

When booting a 2 CPU PAE kernel in bhyve this manifested as a hang before
single user mode.  The attempt to execute /bin/init tried to copy out
the exec strings (argv, etc.) to a non-executable mapping while running
on the AP.  The instruction kept faulting due to invalid bits in the PTE
in an infinite loop.

Fix this by moving the code to enable EFER_NXE out of the switch statement
on 'cpu' and always doing it if 'amd_feature' supports AMDID_NX.

5d8ff54ef5 Correct definition of 'struct sigcontext' on MIPS.
Add missing fields ('sr' and 'mc_tls') to 'struct sigcontext'.

The kernel doesn't use 'struct sigcontext' but instead uses 'ucontext_t'
which includes 'mcontext_t' in 'struct sigframe' to build the signal frame.
As a result, this change is not an ABI change but simply making
'struct sigcontext' correct.  Note that 'struct sigcontext' is only used
for "Traditional BSD style" signal handlers.

While here, rename the 'xxx' field to '__spare__' to match 'mcontext_t'.

8b9e0aaf2a strings: fix exit status if a file before the last one fails
Previously a command like "strings f1 f2 f3" reported the exit status
based only on processing the last file.

As with GNU strings, report an error exit status if an error was
encountered processing any of the files. While here simplify the
exit status handling to just success (0) / failure (1).
