into a single, system-wide table, rather than having a separate hash table
per inode. Significantly reduces the "system" cpu usage of your average
file write.
be assured that the last byte of a file is always allocated. Previously
a file extension could cause the filesystem to be flushed, writing an
inconsistent inode to disk. Although this condition would be corrected
the next time blocks were written to disk, an intervening crash would leave
the filesystem in an inconsistent state, leaving fsck_lfs to complain
of an inode "partially truncated".

Many thanks to Hiroyuki Bessho for testing this driver with the new
aurateconv interface, as I no longer have access to the hardware.

* Return ENXIO from ac97_attach_type if the modem codec fails to power-on.
This will prevent broken AC97 modems *cough*Conexant*cough* from giving
the impression that they will actually work.

12000 was a stupid choice since we don't actually support it in the driver
yet.

the name is from user space.
modstat -n NAME works again.

don't bother to kill processes.

page type balancing rather than spinning unnecessarily.

prevents the compiler (especially gcc -O0) from inserting accesses to
locations in virtual address space when such accesses would fail.
The *DISC definition is only for backward compatibility with deprecated
TIOC[GS]ETD ioctls, and not needed for new TIOC[GS]LINED ioctls.
The value of IRFRAMEDISC has never been correct, so we don't have any
compatibility to be kept.
Just remove the IRFRAMEDISC defintion.
Rather, cast our single vector. We weren't reporting which vector
when panicking, and if somebody uses a vector that isn't
implemented it should be easy enough to trap down anyways.
* Ignore ICH_PCM246_MASK for modem devices
* Set LINE1 rate and level in set_params
* Enable mmap for modem devices. This was previously disallowed due to
the ext_id field not advertising that the device supported variable
rates. Since modems don't use ext_id (they use ext_mid instead), enable
mmap. Multiple rates are supported on AC'97 modems.
fix "warning: resource shortage: %d pages of swap lost".
extent(9) has some undesirable characteristics for swap allocation:
- it involves alloc-to-free.
- its operational cost is O(n*n) where n is number of entries.
