a7ed916993 Explicitly lock Giant in smbus_if methods in the bktr_i2c and iicsmb
drivers for now.  This can be replaced with driver locks when these
drivers are locked.

25f7299f0f Essentially, neither madvise(..., MADV_DONTNEED) nor madvise(..., MADV_FREE)
work.  (Moreover, I don't believe that they have ever worked as intended.)
The explanation is fairly simple.  Both MADV_DONTNEED and MADV_FREE perform
vm_page_dontneed() on each page within the range given to madvise().  This
function moves the page to the inactive queue.  Specifically, if the page is
clean, it is moved to the head of the inactive queue where it is first in
line for processing by the page daemon.  On the other hand, if it is dirty,
it is placed at the tail.  Let's further examine the case in which the page
is clean.  Recall that the page is at the head of the line for processing by
the page daemon.  The expectation of vm_page_dontneed()'s author was that
the page would be transferred from the inactive queue to the cache queue by
the page daemon.  (Once the page is in the cache queue, it is, in effect,
free, that is, it can be reallocated to a new vm object by vm_page_alloc()
if it isn't reactivated quickly enough by a user of the old vm object.)  The
trouble is that nowhere in the execution of either MADV_DONTNEED or
MADV_FREE is either the machine-independent reference flag (PG_REFERENCED)
or the reference bit in any page table entry (PTE) mapping the page cleared.
Consequently, the immediate reaction of the page daemon is to reactivate the
page because it is referenced.  In effect, the madvise() was for naught.
The case in which the page was dirty is not too different.  Instead of being
laundered, the page is reactivated.

Note: The essential difference between MADV_DONTNEED and MADV_FREE is
that MADV_FREE clears a page's dirty field.  So, MADV_FREE is always
executing the clean case above.

This revision changes vm_page_dontneed() to clear both the machine-
independent reference flag (PG_REFERENCED) and the reference bit in all PTEs
mapping the page.

c04ec928d6 o Remove unused cs_debug tunable. I think I added it and then nothing with
it.  Bad imp.  Removing us dips us under 10,000 in size too.
o Replace an unconditional 30ms DELAY (yes, busy wait) with a check of the
  SIBUSY bit in the SelfST register before accessing the eeprom.  This changes
  the time to read the EEPROM from 2 * 20 * 30ms (1.2s) to < 20*25us (.0005s)
  and make the attach of the card tolerable when ethernet media is present.
  Include data from the datasheet about why this works.  While this is a 2500x
  speed increase, it doesn't really matter at all once the card is probed...
o set dev earlier in softc.

fd86b4a48c Add a -w warning flag to ln(1). When the -w option is enabled,
ln(1) checks to see if the source of a symlink, i.e. the file it
should point to actually exists.  The default is the old ln
behavior, that does not check, to avoid surprising people who may
be using ln(1) in scripts or other non-interactive places.

65134490dc Minor clean up to shave about 1.5k off the size of the driver:
o remove unused fields from softc and args from cs_alloc_irq
o remove some commented code that will never be implemented.
o Don't try to send a packet and see if it worked.  We don't
  need this anymore, and it doesn't add any value.
o tweaks for BNC and AUI.
o limit possible time hung in the kernel to 4s rather than 40s.

980aab4117 Support for the XScale PXA255 SoC as found on the Gumstix Basix and Connex
boards.  This is enough to net-boot to multiuser.

Also supported is the SMSC LAN91C111 parts used on the netCF, netDUO and netMMC
add-on boards.

I'll be putting some instructions on how to boot this on the Gumstix boards
online soon.

This is still fairly rough and will be refined over time but I felt it was
better to get this out there where other people can help out.

38e6324da4 This is a rewritten driver for the SMSC LAN91C111. It's based in part on the
sn(4) driver and also looking at newer drivers.  The reason for the rewrite is
to support MII and to try and resolve some performance issues found when trying
to use the sn(4) driver on the Gumstix network boards.

For reference, the SMSC LAN91C111 is a non-PCI ethernet part whose lineage
dates back to Ye Olde Days of ISA.  It seems to get some use in the embedded
space these days on parts lacking on-board MACs or on-board PCI controllers,
such as the XScale PXA line of ARM CPUs.

This also includes a driver for the SMSC LAN83C183 10/100 PHY.

Man page to follow.

82f26711e2 Fix faulty character to control-character conversion for CTRL().
The CTRL() macro seems to perform character to control-character
conversion (i.e. 'A' to 0x01) to lowercase characters. This is actually
not valid. If we use lowercase characters, conversions such as
CTRL('\\') and CTRL('?') will result to invalid conversions.

Because we must still support old source code that uses CTRL() (bad!),
we make CTRL() accept both forms. When the character is a lowercase
character, we perform the old style conversion.

570605957c Fix the media auto code by breaking it :-). Auto now just means 'use
10BaseT' since it required 10BaseT to have carrier to switch to it.
This chip makes it hard to do proper auto, so we don't do it.  We
can't test carrier on things easily.

Don't insist on carrier when we set the media.  Don't report failures.
Remove a 1s! delay that appears to not be needed.
