From e4ac58afdfac792c0583af30dbd9eae53e24c78b Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Mon, 3 Apr 2006 17:56:36 +0100 Subject: [MIPS] Rewrite all the assembler interrupt handlers to C. Saves like 1,600 lines of code, is way easier to debug, compilers frequently do a better job than the cut and paste type of handlers many boards had. And finally having all the stuff done in a single place also means alot of bug potencial for the MT ASE is gone. The only surviving handler in assembler is the DECstation one; I hope Maciej will rewrite it.
