add guards to just make available to the bootblocks what they need.

Calculate i/o starts and sizes in 'proper' sectors rather assuming
512-byte sectors. Unlikely to affect CF's in the near future.

- replace main() with mips_init() so we can save the arguments from uboot to
  pass it to the kernel later on. also use it to get the clock frequency.
- implement getsecs() so the bootprompt timeout works

We have EVP_CIPH_FLAG_DEFAULT_ASN1 in evp.h; no need to keep constructs to
build on pre-EVP_CIPH_FLAG_DEFAULT_ASN1 codebases.

Oops. Correct variable name more likely to compile.
zap trailing whitespace;
Remove signed/unsigned warning, statement before declaration and
add a function to use function pointers that does not take sizeof(fptr).

getentropy on Windows.  It compiles but has not been thoroughly tested yet.

Use a saner and consistent address layout for my network tests that
run over 4 machines.  Add a check-setup target to verify that
interface addresses and routes are properly set up.
revert a few stragglers hiding out
Log a warning whenever RTM_DESYNC is seen. Thus giving entrail
investigators some clue why dhclient may have gotten confused when
some RTM_ messages vanish.

sthen@ thinks this is a good start.
Resize the pcb hashtable automatically.  The table size will be doubled
when the number of the hash entries reaches 75% of the table size.

Fix USB connect freeze by clearing the host port interrupt.

Connects and disconnects have no affect on the machine, just like before
this driver came into existence.

While at it check for a few more interrupt types.
Remove this sentence:
``The probability that a randomly generated key is weak is -1/2^52,
  so it is not really worth checking for them.''

This kind of naively optimistic attitude is not compatible with security.
Refactor out dosigsuspend() function

Kill the last dumb DVACT_DEACTIVATE handlers.
Add devel/cmake bits (rotted in my tree for more than a year) and a short
description of x11/kde4 variables. Everyone is welcome to extend&improve.
