That lets us also get rid of the run-time initialization of protection_map[] and all the ugly module workarounds for PAGE_KERNEL and PAGE_SHARED to deal with the fact that we can't do btfixups for modular code. Signed-off-by: -

Also we can remove BTFIXUPCALL_SWAPO0G0 as that is no longer used. This was rather amusing, we were setting the btfixup vectors based upon cpu type but all to the same exact generic srmmu routines. Furthermore, we were inconsistently marking the fixup as either BTFIXUPCALL_SWAPO0G0 or BTFIXUPCALL_NORM. What a mess, glad we could untangle this stuff. Signed-off-by: -

It is a noop for srmmu - so use a define as sparc64 does. And drop all sparc callers - no need to confuse our-self be calling a noop function. Signed-off-by:

This revealed that the implementation of switch_mm had a bogus extra argument. No harm as said argument was never used - but confusing. Signed-off-by:

Small cleanup to improve readability. Dropped one test for sparc_cpu_model - we already know that only sun4m support floppy. Signed-off-by:

Fix following warning: arch/sparc/include/asm/floppy_32.h:342:5: warning: 'op' may be used uninitialized in this function The warning are legitimite and we can end up using op uninitialized. This fixes build with my gcc on UP. Signed-off-by:

We know this is not a sun4/sun4c - as we checked earlier. So no need to repeat the check. Signed-off-by:

It was present only to support the sun4, sun4c boxes which do not have the "compatible" property in the root-node of the device tree. Signed-off-by:

We already sorted out if we are a sun4/sun4c and halted. So no need to check the prom version as we know this is a v2 or v3 as sun4m, sun4d etc. does not use a v1 prom. Signed-off-by:

We need to do the check before we try to remap the kernel using SRMMU operations. Signed-off-by: -

I left some around, like the ones in the openprom headers, since we need to think about which pieces of those datastructures and code we can completely toss now. Signed-off-by: -

All the remaining references are trivially removed since we've just eliminated the final reference to sparc_cpu_model from assembler code in commit b7d96ce1 ("sparc32: Remove sparc_cpu_model read from floppy interrupt handler.") Signed-off-by:

Since we no longer test the cpu model value, no need to load it into a register any more. It just gets overwritten in the next instruction anyways. :-) Signed-off-by: -

Remove sun4 and sun4c machine ID values from asm/machines.h Also kill NUM_SUN_MACHINES, use ARRAY_SIZE instead. Kill asm/machines.h include and sun4c checks from asm/floppy_32.h Remove asm/machines.h include from setup_32.c and time_32.c, unused. Signed-off-by: -

As we no longer support sun4c we can remove all the code to support remapping the kernel in head_32.S. We also try to tell the user that the machine is not support, in case someone try to boot the kernel on a sun4c one day Signed-off-by:
