For the explicit calls to .udiv/.umul in assembler, I made a mechanical (read as: safe) transformation. I didn't attempt to make any simplifications. In particular, __ndelay and __udelay can be simplified significantly. Some of the %y reads are unnecessary and these routines have no need any longer for allocating a register window, they can be leaf functions. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Use sparc_config to hold the last two function pointers. There was no point generating dedicated _ops structures only for these. Signed-off-by: NSam Ravnborg <sam@ravnborg.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

I ended up renaming set_cpu_int to send_ipi to be consistent all way around. send_ipi was moved to the *_smp.c files so we could call the relevant method direct, without any _ops indirection. Signed-off-by: NSam Ravnborg <sam@ravnborg.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This is the last non-trivial user of btfixup. Like sparc64, use a special patch section to resolve the various implementations of how to read the current CPU's ID when we don't have current_thread_info()->cpu necessarily available.

This eliminated most of the remaining users of btfixup. There are some complications because of the special cases we have for sun4d, leon, and some flavors of viking. It was found that there are no cases where a flush_page_for_dma method was not hooked up to something, so the "noflush" iommu methods were removed. Add some documentation to the viking_sun4d_smp_ops to describe exactly the hardware bug which causes us to need special TLB flushing on sun4d. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This set of changes displays one major danger of btfixup, interface signatures are not always type checked fully. As seen here the iounit variant of the map_dma_area routine had an incorrect type for one of it's arguments. It turns out to be harmless in this case, but just imagine trying to debug something involving this kind of problem. No thanks. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

These were used on sun4c during floppy data transfers since on that chip we had to lock the cpu mappings into the TLB because we cannot take a TLB miss during the assembler floppy interrupt handler that does the data transfer. That is no longer necessary since we've removed sun4c support, thus this stuff can disappear completely. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The magic Swift SRMMU code in question has not been enabled for something on the order of a decade, and it as well as it's comment is there in the history in case we ever need it again. Therefore all implementations are NOPs and we can kill this stuff off. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

We always have this instruction available, so no need to use btfixup for it any more. This also eradicates the whole of atomic_32.S and thus the __atomic_begin and __atomic_end symbols completely. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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: NDavid S.
