9e195f5266 fputs: Return the number of bytes written.
POSIX.1-2008 requires that successful completion simply return a
non-negative integer. We have regularly returned a constant value.
Another, equally valid, implementation convention implies returning
the number of bytes written.

Adopt this last convention to be in line with what Apple's libc
does. POSIX also explicitly notes:

Note that this implementation convention cannot be adhered to for strings
longer than {INT_MAX} bytes as the value would not be representable in the
return type of the function. For backwards-compatibility, implementations
can return the number of bytes for strings of up to {INT_MAX} bytes, and
return {INT_MAX} for all longer strings.

Developers shouldn't depend specifically on either convention but
the change may help port software from Apple.

355920c5b7 Allow MIPS INTRNG code to be built without FDT support.
This patch allows the newly imported INTRNG code to be built without necessarily
having FDT support in the kernel.  This may be useful for some MIPS platforms
that wish to move to INTRNG, but not to FDT at the same time.

Basically all the code is already within ifdef's where FDT is concerned,
it's just the headers that aren't.

ff82ae2996 NTB: workaround for high traffic hardware hang
This patch comes from Dave Jiang's Linux tree, davejiang/ntb.  It hasn't
been accepted into Linus' tree, so I do not have an authoritative SHA1
to point at.  Original commit log:

=====================================================================
A hardware errata causes the NTB to hang when heavy bi-directional
traffic in addition to the usage of BAR0/1 (where the registers reside,
including the doorbell registers to trigger interrupts).

This workaround is only available on Haswell and Broadwell platform.
The workaround is to enable split BAR in the BIOS to allow the 64bit
BAR4 to be split into two 32bit BAR4 and BAR5. The BAR4 shall be pointed
to LAPIC region of the remote host. We will bypass the db mechanism and
directly trigger the MSIX interrupts. The offsets and vectors are
exchanged during transport scratch pad negotiation. The scratch pads are
now overloaded in order to allow the exchange of the information. This
gets around using the doorbell and prevents the lockup with additional
pcode changes in BIOS.

Signed-off-by:	Dave Jiang <dave.jiang@intel.com>
=====================================================================

Notable changes in the FreeBSD version of this patch:
* The MSIX BAR is configurable, like hw.ntb.b2b_mw_idx (msix_mw_idx).
  The Linux version of the patch only uses BAR4.
* MSIX negotiation aborts if the link goes down.

1960ec586d ext2fs: Remove panics for rename() race conditions.
Sync with r84642 from UFS:

The panics are inappropriate because the IN_RENAME flag only fixes a
few of the huge number of race conditions that can result in the
source path becoming invalid even prior to the VOP_RENAME() call.
