MIPS: R1: Fix hazard barriers to make kernels work on R2 also.

2007-11-16T16:22:56Z

patch 572afc248c33c902760f6f24a72c180f0e4f1719 in mainline. Tested with Malta; inflates malta_defconfig by 3932 bytes. Ideally there should be additional configuration to allow getting rid of this overhead but that would be too much complexity at this stage of the release cycle.

[MIPS] Provide empty irq_enable_hazard definition for legacy and R1 cores.

2007-09-10T20:25:28Z

Following a strict interpretation the empty definition of irq_enable_hazard has always been a bug - but an intentional one because it didn't bite. This has now changed, for uniprocessor kernels mm/slab.c:do_drain() [...] on_each_cpu(do_drain, cachep, 1, 1); check_irq_on(); [...] may be compiled into a mtc0 c0_status; mfc0 c0_status sequence resulting in a back-to-back hazard.

[MIPS] Fix pipeline hazard.

2007-03-24T17:01:49Z

In the the sequence: ei .. mfc0 $x, $status the mfc0 may not see the SR_IE bit set. This was a deliberate bug in the kernel code because we knew this was a safe thing to do on all R2 silicon so far but new silicon is changing this. Signed-off-by: Ralf Baechle
