a6765c4b44 libmd: Only define SHA256_Transform_c when using the ARM64 ifunc.
GCC 9 doesn't define a SHA256_Transform symbol when the stub just wraps
SHA256_Transform_c resulting in an undefined symbol for
_libmd_SHA256_Transform in libmd.so.

547566526f Make struct syscall_args machine independent
After a round of cleanups in late 2020, all definitions are
functionally identical.

This removes a rotted __aligned(8) on arm. It was added in
b7112ead32 and was intended to align the
args member so that 64-bit types (off_t, etc) could be safely read on
armeb compiled with clang. With the removal of armev, this is no
longer needed (armv7 requires that 32-bit aligned reads of 64-bit
values be supported and we enable such support on armv6).  As further
evidence this is unnecessary, cleanups to struct syscall_args have
resulted in args being 32-bit aligned on 32-bit systems.  The sole
effect is to bloat the struct by 4 bytes.

8d0b41b058 Handle table attributes in the arm64 kernel map
When getting the arm64 kernel maps sysctl we should look at the table
attributes as well as the block/page attributes. These attributes are
different to the last level attributes so need to be translated.

The previous code assumed the table and block/page attributes are
identical, however this is not the case. Handle the difference by
extracting the code into new helper functions & calling them as needed
based on the entry type being checked.

de9c000ced sdhci_fsl_fdt: Add support for HS200/HS400 modes
The controller requires some custom logic to perform MMC tuning
and to later switch to HS400 mode. Implement it supplying mmcbr_tune
and sdhci_set_uhs_timing devmethods respectivly. Since the latter
is called unconditionally when the ios is updated we need to keep
track of the tuning state in sc and execute the HS400 switch logic
only when required.

Two HS200/HS400 related errata were implemented.
1. In HS400 modes the clock divisors are limited to 4, 8, 12.
   Apply it by falling back to the closes, higher divider when needed.
2. Hardware tuning procedure can sometimes fails. If that is the case
   fallback to the software tuning.

e0f4cdba53 e1000: fix interface capabilities management
The e1000 drivers (em, lem, igb) are currently looking at the
iflib copies of the capabilities bitvectors (scctx->isc_capabilities
and scctx->isc_capenable) rather than the ifnet ones
(ifp->if_capabilities and ifp->if_capenable). However, the latter
are the ones that are actually updated by ifconfig and that should
be used by the drivers during interface operation. The former are
set by the driver on interface attach (for iflib internal use)
and should not be used anymore by the driver.
This patch fixes the e1000 driver to use the correct bitvectors.

49c2c62889 sys/_bitset.h: Fix fall-out from commit 5e04571cf3
The changes to the bitset macros allowed sched.h to be included
into userland programs without name space pollution due to BIT_*
and BITSET_* macros.

The definition of a "struct bitset" had been overlooked. This name
space pollution caused the build of port print/miktex to fail.

This commit makes the definition of struct bitset depend on the
same condition as the visibility of the BIT_* and BITSET_* macros,
i.e. needs _KERNEL or _WANT_FREEBSD_BITSET to be defined before
including sys/_bitset.h.

It has been tested with "make universe" since a prior attempt to
fix the issue broke the PowerPC64 kernel build.

This commit shall be MFCed together with commit 5e04571cf3.

22c4ab6cb0 sys/_bitset.h: Fix fall-out from commit 5e04571cf3
There is a reference to malloc() in #define __BITSET_ALLOC. Even
though this macro is only defined but not used, it causes the lang/gcc
ports to fail. The gcc ports "poison" a number of functions including
malloc() and prevent their use (including in macro definitions).

This commit moved the declaration of __BITSET_ALLOC into the
conditional block that depends on _KERNEL or _WANT_FREEBSD_BITSET
being defined.

There is no use of __BITSET_ALLOC in the FreeBSD sources, and userland
programs that want to use BITSEC_ALLOC will define _WANT_FREEBSD_BITSET
anyway.

This patch has been tested by building lang/gcc11 and a successful
make buildworld.

This commit shall be MFCed together with commit 5e04571cf3.

This fix has been suggested by kib. It has been tested to let the
build of the print/miktex port succeed and to not break buildworld.

25927e068f fusefs: correctly handle an inode that changes file types
Correctly handle the situation where a FUSE server unlinks a file, then
creates a new file of a different type but with the same inode number.
Previously fuse_vnop_lookup in this situation would return EAGAIN.  But
since it didn't call vgone(), the vnode couldn't be reused right away.
Fix this by immediately calling vgone() and reallocating a new vnode.

This problem can occur in three code paths, during VOP_LOOKUP,
VOP_SETATTR, or following FUSE_GETATTR, which usually happens during
VOP_GETATTR but can occur during other vops, too.  Note that the correct
response actually doesn't depend on whether the entry cache has expired.
In fact, during VOP_LOOKUP, we can't even tell.  Either it has expired
already, or else the vnode got reclaimed by vnlru.

Also, correct the error code during the VOP_SETATTR path.

169b368a62 amd64: Pass DEBUG when building VDSO wrapper
Not doing so results in ctfconvert failing with

  ERROR: ctfconvert: elf-vdso.so.o doesn't have type data to convert

On FreeBSD this is non-fatal, since the ctf tools have a hack to make
such errors not fail the build and instead just silently continue
without CTF data (which is a bad idea these days and should probably be
removed; they date back to the original import). However, those are
under #ifdef __FreeBSD__ so do not apply when cross-building from
non-FreeBSD, causing the build to fail.

Fix this by forwarding DEBUG on to the compiler invocation for the VDSO
wrapper. It's assembly so it's not hugely useful, but there is a
non-zero amount of information preserved, and other assembly files are
built with -g by default too so this matches them; the alternative would
be to tag the files.amd64 entries with no-ctfmerge. Note that the VDSO
itself is still compiled without debug info, this only affects the
wrapper linked into the kernel.
