Module Name: src Committed By: maxv Date: Sun Oct 16 10:38:49 UTC 2016
Modified Files: src/sys/arch/i386/i386: vector.S Log Message: Use offsets to access the TPR, and not lapic_tpr. For the record: I'm not sure exactly why it was originally done this way, and the cvs logs are not quite enlightening. It might have been a way to speed up the asm access, but it would sound a little bizarre since there are many more legitimate reasons to do it on the EOI register instead.
