locking, m68k/asm-offsets: Rename signal defines
Browse files Browse the repository at this point in the history
In order to be able to use asm-offsets.h in C files the
existing namespace conflicts must be solved first. In
asm-offsets.h there are defines for signal constants, so they
can be used in assembler files.

Unfortunately the existing defines use a 1:1 mapping for the
macro names which results in name space conflicts if the header
file would also be used in C files. So rename the created
defines and add an "L" prefix to each one since that has
already been done for the SIGTRAP define in entry_mm.
