[PATCH] powerpc: Merge bug.h

Browse Source 
ppc32/ppc64: Merge bug.h into include/asm-powerpc

This patch merges bug.h into include/asm-powerpc.  Changed the data
structure for bug_entry such that line is always an int on both 32 and
64-bit platforms; removed casts to int from the 64-bit trap code to
reflect this.
