head_32.S failed to set cputypval for leon, causing boot to fail. The boot failed because we failed to recognize this was a LEON cpu so we did not preoperly run-time patch the the kernel.

UltraSPARC-T2 and later do not use the fp_exception_other trap and do not set the floating point trap type field in the %fsr at all when you try to execute an unimplemented FPU operation. Instead, it uses the illegal_instruction trap and it leaves the floating point trap type field clear. So we should not validate the %fsr trap type field when do_mathemu() is invoked from the illegal instruction handler. Also, the floating point trap type field is 3 bits, not 4 bits.

Davis S. Miller wrote: " The way we do that now is overkill. We only needed to use the MMU cache ops when we had sun4c around because sun4c lacked support for the "flush" instruction. But all sun4m and later chips have it so we can use it unconditionally. So in the per_cpu_patch() code, get rid of the cache ops invocation, and instead execute a "flush %reg" after each of the instruction patch assignments, where %reg is set to the address of the instruction that was stored into. Perhaps take the flushi() definition from asm/cacheflush_64.h and place it into asm/cacheflush.h, then you can simply use that. " Implemented as per suggestion. Moved run-time patching before we call paging_init(), so helper methods in paging_init() may utilise run-time patching too. Signed-off-by: NSam Ravnborg <sam@ravnborg.org> Signed-off-by: NDavid S.

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>
