r366344 corrected the optimized amd64 skein assembly implementation, so

that it will be rebuit (similar to r366362).

2ffad162f3 Modify mountd.c so that it does not always malloc 4K for the map credentials.
r362163 upgraded mountd so that it could handle MAX_NGROUPS
groups for the anonymous user credentials (the ones provided by
-maproot and -mapall exports options).
The problem is that this resulted in every export structure growing by
about 4Kbytes, because the cr_groups field went from 16->MAX_NGROUPS.

This patch fixes this by only including a small 32 element cr_groups in the
structure and then malloc()'ng cr_groups when a larger one is needed.
The value of SMALLNGROUPS is arbitrarily set to 32, assuming most users
used by -maproot or -mapall will be in <= 32 groups.

31deb3cc76 cxgbe(4): More fixes for the T6 FCS error counter.
r365732 was the first attempt to get an accurate count but it was
writing to some read-only registers to clear them and that obviously
didn't work.  Instead, note the counter's value when it is supposed to
be cleared and subtract it from future readings.

dev.<port>.stats.rx_fcs_error should not be serviced from the MPS
register for T6.

The stats.* sysctls should all use T5_PORT_REG for T5 and above.  This
must have been missed in the initial T5 support years ago.  Fix it while
here.

19fe23fa2b Make vn_generic_copy_file_range() interruptible via a signal.
Without this patch, when vn_generic_copy_file_range() is
doing a large copy, it will remain in the function for a
considerable amount of time, delaying handling of any
outstanding signals until the copy completes.

This patch adds checks for signals that need to be
processed after each successful data copy cycle.
When sig_intr() returns non-zero, vn_generic_copy_file_range()
will return.
The check "if (len < savlen)" ensures that some data
has been copied, so that progress will be made.

Note that, since copy_file_range(2) is allowed to
return fewer bytes copied than requested, it
will never return EINTR/ERESTART when sig_intr()
returns non-zero.

c6d56081c9 Initial support for implementing the bootXXX.efi workaround
Too many version of UEFI firmware (so far only confirmed on amd64)
don't really support efibootmgr selection of boot. That's the most
reliable, when it works, since there's no guesswork. However, many do
not save, unmolested, the variables that efibootmgr sets, so as a
fallback we also install loader.efi as bootXXX.efi (where XXX is
either aa64 or x64) if it doesn't already exist in /efi/boot on the
ESP. The standard only defines this for removable devices, but it's
almost ubiquitously used as a fallback. Many BIOSes implement a drive
selection feature that takes over the efibootmgr protocol, rendinering
it useless (either generally, or for those vendors not on the short
list). bootxxx.efi works around this. However, we don't install it
unconditionally there, as that breaks some popular multi-boot setups.

e1ef4c29a3 Do not leak B_BARRIER.
Normally when a buffer with B_BARRIER is written, the flag is cleared
by g_vfs_strategy() when creating bio.  But in some cases FFS buffer
might not reach g_vfs_strategy(), for instance when copy-on-write
reports an error like ENOSPC.  In this case buffer is returned to
dirty queue and might be written later by other means.  Among then
bdwrite() reasonably asserts that B_BARRIER is not set.

In fact, the only current use of B_BARRIER is for lazy inode block
initialization, where write of the new inode block is fenced against
cylinder group write to mark inode as used.  The situation could be
seen that we break dependency by updating cg without written out
inode.  Practically since CoW was not able to find space for a copy of
inode block, for the same reason cg group block write should fail.

22e6a67086 Add a routine to dump boot metadata
The boot metadata (also referred to as modinfo, or preload metadata)
provides information about the size and location of the kernel,
pre-loaded modules, and other metadata (e.g. the EFI framebuffer) to be
consumed during by the kernel during early boot. It is encoded as a
series of type-length-value entries and is usually constructed by
loader(8) and passed to the kernel. It is also faked on some
architectures when booted by other means.

Although much of the module information is available via kldstat(8),
there is no easy way to debug the metadata in its entirety. Add some
routines to parse this data and allow it to be printed to the console
during early boot or output via a sysctl.

Since the output can be lengthly, printing to the console is gated
behind the debug.dump_modinfo_at_boot kenv variable as well as the
BOOTVERBOSE flag. The sysctl to print the metadata is named
debug.dump_modinfo.
