URL: http://svn.reactos.org/svn/reactos?rev=49573&view=rev Log: [FREELDR] Convert most of the trap and blue screen code from asm to C, use KTRAP_FRAME and KSPECIAL_REGISTERS on the stack, instead of using a bunch of global variables. Convert multiply used asm code chunks into macros. Use intel syntax for remaining asm. 135 lines of C + 178 lines of asm, instead of 942 lines of asm
