* expmed.c (expand_shift): Additionally check that the shift_cost
is not MAX_COST and that INTVAL(op1) is less than MAX_BITS_PER_WORD
before implementing a LSHIFT_EXPR as a sequence of additions.
* config/sh/sh.c (shift_costs): Return MAX_COST to inform the
middle-end that DImode shifts need to be synthesized by expand.

Explain that the UGEN_BULK_RA_WB option enables the USB_SET_BULK_*
ioctls.
Explain that select works in BULK mode, but not in the unbuffered
mode.
Explain more clearly that UGEN_SET_BULK_RA causes the driver to read
from the device whenever there is space in the buffer.
- adapt to NVERIEXEC in init_sysctl.c.
- we now need "veriexec.h" for NVERIEXEC.
- "opt_verified_exec.h" -> "opt_veriexec.h", and include it only where
it is needed.
ahead and write behind, improving performance for the Universal
Software Radio Peripheral (USRP) used with GNU Radio.
Enable UGEN_BULK_RA_WB in GENERIC and GENERIC_LAPTOP; behavior is
unchanged unless the new ioctl is called.
This code was written by Joanne Mikkelson under funding from DARPA's
ACERT program.

but does not check when strftime fails because the buffer is too small.
Our implementation of strftime does not NUL terminat the buffer
on failure (it does not have to; the results are undefined), so
garbage gets printed. Use a dynamically allocated buffer instead.
commands to the controller.
Add a amrctl(8) control tool, which for now only allows to get status
from the adapter (status of adapter, logical volumes and and individual
drives).
From FreeBSD, with some adjustements by Andrew Doran and me.
(mostly based on pmax)
- pass symbol info from bootloader to kernel via bootinfo
(currently bootinfo is allocated in the bootloader and
copied by kernel later; maybe we should rethink about this)
- use passed bootinfo to initialize ksyms(4) in kernel
- remove options SYMTAB_SPACE from kernel config files
- bump bootloader version
