I hope that this and the i386 version of it will not be needed, but
this is currently about 16 cycles or 36% faster than the C version,
and the i386 version is about 8 cycles or 19% faster than the C
version, due to poor optimization of the C version.

semaphore wouldn't be freed.

destroy call; this transpired because the inpcb alloc path for IPv4/IPv6
is the same code, but IPv6 has a separate free path. The results was
that as new IPv6 TCP connections were created, kernel memory would
gradually leak.

- Import latest changes to cxgb_main.c and cxgb_sge.c from toestack p4 branch
- make driver local copy of tcp_subr.c and tcp_usrreq.c and override tcp_usrreqs so
TOE can also functions on versions with unmodified TCP
- add cxgb back to the build
- rename tcp_ofld.[ch] to tcp_offload.[ch]
- document usage and locking conventions of the functions in the
toe_usrreqs function vector
- document tcpcb, inpcb, and socket fields used by toe
- widen the listen interface into 2 functions
- rename DISABLE_TCP_OFFLOAD to TCP_OFFLOAD_DISABLE
- shrink conditional compilation to reduce the likelihood of bitrot
- replace sc->sc_toepcb checks in tcp_syncache.c with TOEPCB_ISSET
deallocation and dynamic load balancing via the MALLOC_LAZY_FREE and
MALLOC_BALANCE knobs. This is a non-functional change, since these
features are still enabled when possible.
Clean up a few things that more pedantic compiler settings would cause
complaints over.
adds two new directories in msun: ld80 and ld128. These are for
long double functions specific to the 80-bit long double format
used on x86-derived architectures, and the 128-bit format used on
sparc64, respectively.
says they are never supposed to, and the fact that they did could
cause apps that run with unmasked FP exceptions to SIGFPE after a
scanf() or strtod(). The vendor stated that he will not be fixing
this, citing portability concerns.
- Accept the '0x' prefix so strtod("nan(0x...)", NULL) returns the same
thing as gcc's builtin nan("0x...") for such strings.
- Don't return uninitialized memory.
- Finish processing the string up to the closing ')' (provided it's
lexically valid) for compatibility with C99 and *scanf().
Implement -E option which will erase the filesystem sectors before
making the new filesystem. Reserved space in front of the superblock
(bootcode) is not erased.
NB: Erasing can take as long time as writing every sector sequentially.
This is relevant for all flash based disks which use wearlevelling.
or any other bio chopping geom a reasonable size of work.
Check for delivered signals between chunks, because the request size
and service time is unbounded.
