4Subject: [PATCH 1/3] Ignore differences between mips machine identifiers
5
6Little endian binaries actually use EM_MIPS so you can't tell the endianness
7from the elf machine id. Also, the EM_MIPS_RS3_LE machine is dead anyway (the
8kernel will not load binaries containing it).

4Subject: [PATCH 3/3] Add mips n64 relocation format hack
5
6MIPSEL N64 ELF files use a slightly different format for storing relocation
7entries which is incompatible with the normal R_SYM / R_INFO macros.
8To workaround this, we rearrange the bytes in the relocation's r_info field
9when reading and writing the relocations.
10
11This patch also ensures that strip.c sets the correct value of e_machine
12before manipulating relocations so that these changes take effect.

1GCC7 adds -Wimplicit-fallthrough to warn when a switch case falls through,
2however this causes warnings (which are promoted to errors) with the elfutils
3patches from Debian for mips and parisc, which use fallthrough's by design.
4
5Explicitly mark the intentional fallthrough switch cases with a comment to
6disable the warnings where the fallthrough behaviour is desired.
