path. When the taken branch leaves the kernel and enters the process,
we still need to execute the instruction at that address. Don't raise
SIGTRAP when we branch into the process, but enable single-stepping
instead.
is sufficiently different that it was simpler to just put separate
reporting functions into read.c and write.c rather than try to have
a single all-purpose reporting function.
Switch to a custom function for converting int64_t to a string; in
the portable version, this saves a lot of configuration headaches
trying to decipher the platform printf().
use -b 2048 (1MiB block size). Setting the limit to 8192 should
allow some room for growth while still helping people who mistakenly
put in byte counts here instead of block counts.
_PDC was deprecated in favor of _OSC long time ago, but it
seems that they still peacefully coexist and in some case
only _PDC is present.
Still _OSC provides a reacher interface and is capable to
report back its status.
If the status is non-zero, then report it, we may find
it useful to understand what firmware expects from OS.
Also clean up some comments that became less useful over time.

The bc(1) program may need to deal with files when it's being run in
interactive mode, so we can not blindly use interactive mode (in turn
use libedit) but need to check if the input source is really the standard
input.
This commit should fix a regression where 'bc -l' would not parse the
mathlib.

disabling interrupts.
Simplify register usage - we can directly load 'curpcb' into 'k1' after
interrupts are disabled. There is no need to do so indirectly through 'a1'.
The only reason we need to have the sb_load64() and sb_store64()
functions in assembly is to cheat the compiler and generate the
'ld' and 'sd' instructions which it otherwise will not do when
compiling for a 32-bit architecture. There are some 64-bit
registers in the SCD unit that must be accessed using 64-bit
load and store instructions.
providers for writing provokes huge traffic related to taste events send
by GEOM on close. This can lead to various problems with opening GEOM
providers that are created on top of other GEOM providers.
