838200ff96 Document modff() and modfl(). Technically, modff() and modfl()
live in libm, while modf() lives in libc due to historical
mistakes. I'm claiming in the manpage that they all live in libm,
since programmers should not rely on the mistake.

52481a9a9d - Use vm_object_reference_locked() directly from
vm_object_reference().  This is intended to get rid of vget()
   consumers who don't wish to acquire a lock.  This is functionally
   the same as calling vref(). vm_object_reference_locked() already
   uses vref.

ed271d5c67 Bump __FreeBSD_version in order to reflect BUF_LOCKWAITERS() reintegration

71072af500 b_waiters cannot be adequately protected by the interlock because it is
dropped after the call to lockmgr() so just revert this approach using
something similar to the precedent one:
BUF_LOCKWAITERS() just checks if there are waiters (not the actual number
of them) and it is based on newly introduced lockmgr_waiters() which
returns if the lockmgr has waiters or not. The name has been choosen
differently by old lockwaiters() in order to not confuse them.

KPI results enriched by this commit so __FreeBSD_version bumping and
manpage update will be happening soon.
'struct buf' also changes, so kernel ABI is disturbed.

856744ba93 When retasting, wither any existing GEOMs of the same class. This
allows the class to create a different GEOM for the same provider
as well as avoid that we end up with multiple GEOMs of the same
class with the same name.

For example, when a disk contains a PC98 partition table but
only MBR is supported, then the partition table can be treated
as a MBR. If support for PC98 is later loaded as a module, the
MBR scheme is pre-empted for the PC98 scheme as expected.

99c8ae87a4 In revision 1.70, 1.71 and 1.84 re(4) tried to workaround checksum
offload bugs by manual padding for short IP/UDP frames. Unfortunately
it seems that these workaround does not work reliably on newer PCIe
variants of RealTek chips.

To workaround the hardware bug, always pad short frames if Tx IP
checksum offload is requested. It seems that the hardware has a
bug in IP checksum offload handling. NetBSD manually pads short
frames only when the length of IP frame is less than 28 bytes but I
chose 60 bytes to safety. Also unconditionally set IP checksum
offload bit in Tx descriptor if any TCP or UDP checksum offload is
requested. This is the same way as Linux does but it's not
mentioned in data sheet.

244586d6f1 Remove ng_setisr() call from ng_dequeue(). It is useless as we any way
will never exit ngintr(), while there is some ready requests on the queue.
It was made years ago with hope of parallel queue processing by several
net threads. But even if we have several threads sometimes, we have no
rights to process queue in parallel as it will break original requests
serialization that is critically important for some setups.

97dbe5e48e MFamd64 with few changes:
1. Add support for automatic promotion of 4KB page mappings to 2MB page
   mappings.  Automatic promotion can be enabled by setting the tunable
   "vm.pmap.pg_ps_enabled" to a non-zero value.  By default, automatic
   promotion is disabled.  Tested by: kris

2. To date, we have assumed that the TLB will only set the PG_M bit in a
   PTE if that PTE has the PG_RW bit set.  However, this assumption does
   not hold on recent processors from Intel.  For example, consider a PTE
   that has the PG_RW bit set but the PG_M bit clear.  Suppose this PTE
   is cached in the TLB and later the PG_RW bit is cleared in the PTE,
   but the corresponding TLB entry is not (yet) invalidated.
   Historically, upon a write access using this (stale) TLB entry, the
   TLB would observe that the PG_RW bit had been cleared and initiate a
   page fault, aborting the setting of the PG_M bit in the PTE.  Now,
   however, P4- and Core2-family processors will set the PG_M bit before
   observing that the PG_RW bit is clear and initiating a page fault.  In
   other words, the write does not occur but the PG_M bit is still set.

   The real impact of this difference is not that great.  Specifically,
   we should no longer assert that any PTE with the PG_M bit set must
   also have the PG_RW bit set, and we should ignore the state of the
   PG_M bit unless the PG_RW bit is set.

d97cdd3349 Allow awk (the one true one!) to handle 64 files instead of just 20.
The current FreeBSD syscall generation script uses all 20 and I need
another open file.

It's a shame that something named as the 'one-true-awk' is so limited
by an old denition like FOPEN_MAX when it could just make the file
handling dynamic.

This is done to avoid touching contrib sources on a vendor branch.
