that is priority is rasied. Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.
This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).
XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX. This platforms still have this bug until their
XXX spl*() functions are fixed.
appropriate spl* macros.
Move spllpt() maro here from intr.h
Prototype setsoftserial().
Define spl_smasks array for software interrupt masks to complement the
hardware interrupt masks.
- Most changes are comment cleanups.
_ iomd.h is no longer an exported header.
- Added intr.h for MI interrupt definitions.
- Added definitions for ARM8 cpu.
- Added bus dma support.
