Subject: MIPS: kernel: entry.S: Set correct ISA level for mips_ihb
To: stable@xxxxxxxxxxxxxxx
Message-ID: <48b943431ab90523cb388d461fb30c585c2d27f9.1431087908.git.ralf@xxxxxxxxxxxxxx>
From: Markos Chandras <markos.chandras@xxxxxxxxxx>
Commit aebac99384f7a6d83a3dcd42bf2481eed2670083 upstream.
Commit 6ebb496ffc7e("MIPS: kernel: entry.S: Add MIPS R6 related
definitions") added the MIPSR6 definition but it did not update the
ISA level of the actual assembly code so a pre-MIPSR6 jr.hb instruction
was generated instead. Fix this by using the MISP_ISA_LEVEL_RAW macro.
