Subject: powerpc: Fix BUG/WARN macros for 64-bit
X-Git-Tag: v3.12-rc1~40567^2~16^2~28

powerpc: Fix BUG/WARN macros for 64-bit

The bug_entry struct had an int in the middle of pointers and unsigned
longs, and the inline asm that generated the bug table entries didn't
insert the necessary padding, so the fields following it didn't get
initialized properly and an oops resulted.  This changes the int field
(the line number) to a long so that all the fields are the same size
and no padding is required.
