they are now deprecated in favour of the new generic sleep types.

amd64: remove assertion about sizeof(struct pcb)
We no longer put pcb on stack, it is part of the struct thread.
Similarly, we do not put user fpu save area on stack. There is no
constraints on the pcb size due to the XSAVE area required alignment.

HBSD: Append to SHARED_CFLAGS
PICFLAG should not be modified by individual components in base.
Instead, use SHARED_CFLAGS to set the -DOPENSSL_PIC flag.
FreeBSD reverted the bad commit, whereas HardenedBSD fixed the problem
they introduced.

amd64: check that %cs and %ss values from ucontext fit into registers
This change only checks that the values from the user-supplied context
are not truncated by C implicit type convertions. The validity of the
segment selectors is still checked by hardware.

x86 FRED: add hardware definitions for the trap frames fields
as provided by the Intel document 346446-009 AKA FRED 8.0 and SDM v90,
February 2026.
Note that the layout of the struct trapframe does not change with
FRED. The differences are in addition of two fields at the end of the
structure. Other members are carved from existing tf_cs and tf_ss by
limiting hw-written segments to 16 bits officially, and reusing rest
from the doubleword for the new data.

Revert "libcrypto: compile all PIC objects with -DOPENSSL_PIC"
This commit broke the build with some build options.
Some validation needs to be done to confirm that moving the preprocessor
argument to `secure/lib/libcrypto/Makefile.inc` works without breaking
the build, but revert for now until a `tinderbox` run can be done with
the change.

Makefile.inc1: Don't force LLVM_BINUTILS off for cross-tools
Because of this setting we were still using ELF Tool Chain tools for
buildworld. The sets of binary utilities are largely equivalent and
this went unnoticed after commit 1cae7121c667 ("Enable LLVM_BINUTILS
by default").
This was discovered recently because ELF Tool Chain objcopy produces
standalone debug files without phdrs and this caused an issue with a
3rd party ELF parser [1]. Remove the forced setting so that we use
LLVM's binutils to build the system.

Re-commit after fixing a bootstrapping issue with LLVM binutils (in
17494c6e6b7d "build: Boostrap LLVM_BINUTILS for cross-tools").

tpm: fix multi-threaded access with per-open state
The TPM driver currently has a single buffer per instance to hold the
result of a command, and does not allow subsequent commands to be sent
until the current result is read by the same OS thread that sent the
command, with a timeout to throw away the result after a while if the
result is not read in a timely fashion. This has a couple problems:
- The timeout code has a bug which causes all subsequent commands to
hang forever if a different OS thread tries to read the result
before the OS thread which sent the command, and the OS thread
which sent the command never tries to read the result.
- Even if the first problem is fixed, applications expect to be able
to read the result from a different OS thread than the OS thread
which sent the command. The particular case that we saw was a go
application where the go runtime scheduled the goroutine which read
the result to a different OS thread from one where the goroutine
that sent the command ran, and there's no way to force these to

cam (scsi): silence "Medium not present" SCSI sense logging for removable media
Change SS_FATAL to SS_FAIL for SCSI sense code 0x3A (Medium not present)
to suppress console spam when card readers or other removable media
devices have no media inserted.
The error is still returned to callers (ENXIO), but no longer prints to
dmesg during boot/probe.
Verified with Apple SD Card Reader - reduced boot messages from 4 to 2.

loader(8): embedded MD should be the most preferred currdev
A loader built with MD_IMAGE_SIZE is almost always meant for use with
its embedded image and should try that as currdev before anything else.
Recent changes (d69fc3a9dc71, 784150fd2535) seem to have relaxed the ZFS
code's search for a rootfs and exposed this problem.
