symbols, and made it impossible for the kernel to use that value, and
correctly find symbols from LKMs.
o Allow LKM users to use DDB to debug the entry function of a LKM by
loading the symbol table with the temporary name /lkmtemp/ before calling
it, and then renaming it once we know the module name.

may turn into exceptions on Mach: a small message sent by the kernel to
the task that requested the exception.
On Darwin, when an exception is sent, no signal can be delivered.
TODO: more exceptions: arithmetic, bad instructions, emulation, s
software, and syscalls (plain and Mach). There is also RPC alert, but
I have no idea about what it is.
While we are there, remove some user ktrace in notification code, and add
a NODEF qualifier in mach_services.master: it will be used for notifications
and exceptions, where the kernel is always client and never server: we
don't want the message to be displayed as "unimplemented xxx" in kdump (thus
UNIMPL is not good), but we don't want to generate the server prototype
(therefore, STD is not good either). NODEF will declare it normally in the
name tables without creating the prototype.
local-loopback (lo0). As posted for review on tech-kern 2003-18-09,
with a long comment explaining (one of) the deadlock scenarios.
I've used this since shortly after 2002-09-12-, without noticing
performance degradataion or instability for non-loopback mounts.
- tweak some attach messages
- establish interrupt after all dma resouces are successfully allocated
- wrap an assertion with #ifdef DIAGNOSTIC
- assume NCRCFG2_FE bit is always enabled
- call bus_dmamap_sync for mdldmap at POSTWRITE for consistency
- pass proper dmamapsize for mdldmap
crossing boundary in iommu_dvmamap_load().
Fixes E2BIG error on dmamap with smaller boundary size than maxxfersize
(which is used by recent changed pcscp(4)).
While here, some KNF around debug printf etc.
the functionality of ixp425_bs_tag.
- Add missing stream_{read,write}_1 ops to ixp425_bs_tag.
- Re-work the delay() implementation to use the free-running Time-
Stamp counter. This removes the need to bootstrap TMR0 early on.
bswapl, and bf_cbc.S uses it. Unfortunately, this means that GENERIC
will no longer use the asm code -- though it will still use the asm
for the basic Blowfish transform. This won't slow down the KAME IPsec
(since it rolls its own CBC) but may slow down fast-ipsec in kernels
that have I386_CPU defined.
