implies that _UC_CPU must be set in the context passed. Check for this
and return EINVAL if not; this gives a cheap test for corrupted
ucontexts eg on a signal handler stack which would go unnoticed otherwise.
-Don't ckeck for NULL ucontext pointers explicitely. This is an error,
except in the swapcontext() case where it can be easily caught in
userland.
required to initialize ksyms_hdr. Otherwise LKMs do not work when using
ksyms_init_explicit instead of ksyms_init, as is the case of booting an
i386 kernel using Multiboot.

all the places we call ksiginfo_queue() without a ksiginfo.

XXX: We still install rmd160.h and sha2.h in /usr/include/crypto, unlike
the other hash functions which get installed in /usr/include for compatibility.
allowed. It takes three int * arguments indicating domain, type, and
protocol. Replace previous KAUTH_REQ_NETWORK_SOCKET_RAWSOCK with it (but
keep it still).
Places that used to explicitly check for privileged context now don't
need it anymore, so I replaced these with XXX comment indiacting it for
future reference.
Documented and updated examples as well.
exact address of the symtab and strtab ELF sections contents beforehand.
This will be used in i386's Multiboot code to add the initial kernel ksyms
without having to prepare a minimal ELF image that matches the format
expected by the reguluar ksyms_init function.
This part was reviewed by cube@ and successfully passes a full i386 release
build.
for the disk.
- Add a new function, disk_ioctl(), that does generic disk ioctl handling.
DIOCGDISKINFO is handled here now, and others will be added in the future.
- In the wd driver, fill in the dk_info member of struct disk and use the
new disk_ioctl() function.
Make some "#ifdef DIAGNOSTIC" blocks always compiled in; others
convert to KASSERT() where appropriate.
Add some sanity checks and comments while here.
Add _lwp_getspecific_by_lwp() to get lwp specific data from other lwp's.

pool_get(). pre-allocate the ksiginfo_t before taking sched_lock and
use it if necessary, or freeing it if it is unused.
rename ksiginfo_{get,put}() to ksiginfo_{dequeue,queue}() (idea from chuq.)
this fixes PR#32962. thanks to christos, chuq and go for help/ideas.
