4ab7f34ea0 Workaround for fishy situation that caused checksum on outgoing packets
to be broken in certain cases. (Seemingly when 2 short packets sent
back-to-back.) Buffer alignment seems to fix this ...

355a10864b Fixed various GCC compiler warnings for the kernel.
Only main() now gives a warning about the return type (GCC wants an int).

3eeff022fb Added function read_cpu_flags() that returns current cpu flags as a
long.  This is used to check for interrupts being disabled at the time
of a lock() call, if enabled in config.h. The number of times this
happens is then counted in the kinfo structure. These events (recursive
lockings) lead to nasty race conditions.

ec24a0798c Updated function key mapping because of possible changes to NOTIFY.
The TTY driver now only notifies the IS server about function key event,
but does not tell which keys are pressed. The IS servers queries the TTY
driver to find out about this.

c9c6983cc1 Fixed a few quirks in misc.c
. MAX used where it should've been MIN
  . buffer byte too short
  . inobvious use of & with && without parantheses
  . funny length checking

45ddea1cdd Fixed bug that caused the PM to brutalize the contents of the 'memory'
variable. Parsing worked, but future requests for the variable (such as
by the sysenv command) returned truncated data. This caused the system
(e.g. setup script) to think the amount of memory was tiny, and caused
the enabling of swapspace, while it is unnecessary.

d844d2a547 Fixed nasty bug that would cause FS to loop forever in rw_scattered (while
syncing, for instance) if blocks are unwritable. This could happen if:

  . write goes beyond device boundary to a block device
  . write is done for a complete block or more; thus the
    block is not retrieved first (at which point it would be noticed
    it doesn't exist), but the buffer is simply allocated
  . at write time, the device i/o doesn't succeed, but rw_scattered
    doesn't understand this and loops forever trying to get the block
    written.

Currently, if no blocks can be written, the loop aborts, leaving all
buffers intact but potentially dirty. When invalidate() is called on the
device, the buffers will disappear (even if dirty). Same story for if
the buffer is removed due to rmed from lru chain. There's not much we
can do about this, however - we can't keep these blocks around, forever
occupying a buffer in the buffer cache.

The second part of the solution is not to let unwritable buffers be
created in the first place. How to do this, however, without doing a
wasteful read first?

It looks like this code was in 2.0.4 too.

34a9677a5b Made mkfs a little smarter about how to report empty devices.
Also a little smarter about manually specified number of blocks that is
larger than the device capacity.
