New Revision: 204309
URL: http://svn.freebsd.org/changeset/base/204309
Log:
Introduce the new kernel sub-tree x86 which should contain all the code
shared and generalized between our current amd64, i386 and pc98.
This is just an initial step that should lead to a more complete effort.
For the moment, a very simple porting of cpufreq modules, BIOS calls and
the whole MD specific ISA bus part is added to the sub-tree but ideally
a lot of code might be added and more shared support should grow.

+ * all level triggered interrupts use active-lo polarity.
+ *
+ * The format of the ELCR is simple: it is a 16-bit bitmap where bit 0
