2012-05-13sparc32: drop btfixup in pgtable_32.hSam Ravnborg
Only one function left using btfixup. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-05-12sparc32: Pass -mcpu=v7 explicitly to gcc.David S. Miller
We should be agnostic to what gcc happens to be generating by default. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: Un-btfixup more PTE constants and PTE ops.David S. Miller
pte_{filei,wrprotecti,mkcleani,mkoldi} pte_{mkwrite,mkdirty,mkyoung} Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: Un-btfixup pte_{write,dirty,young}iDavid S. Miller
And we can certainly get rid of the const function attributes, there is no way that's needed any longer and no other arch uses this kind of annotation here. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: drop unused code in process_32Sam Ravnborg
It is commented out using #ifdef 0 / #endif, and has been so for a long time. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: Un-btfixup set_pte, pte_present, mk_pte{_phys,_io}().David S. Miller

2012-05-12sparc32: Un-btfixup pgd_{none,bad,present}.David S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: Un-btfixup PAGE_{NONE,COPY,READONLY,SHARED,KERNEL}.David S. Miller
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: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: Un-btfixup pmd_page and pte_pfn.David S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: Un-btfixup {pte,pmd,pgd}_clear().David S. Miller
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: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: Un-btfixup PGDIR_{SHIFT,SIZE,MASK} {USER_,}PTRS_PER_{PGD,PMD}David S. Miller
Only one set of values exist, the SRMMU ones. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: drop unused type/externSam Ravnborg
Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: drop btfixup for check_pgt_cacheSam Ravnborg
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: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: drop btfixup for switch_mmSam Ravnborg
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: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: code cleanup in floppy glueSam Ravnborg
Small cleanup to improve readability. Dropped one test for sparc_cpu_model - we already know that only sun4m support floppy. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: fix warning in floopy glueSam Ravnborg
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: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: simpler cputype check in head_32.SSam Ravnborg
We know this is not a sun4/sun4c - as we checked earlier. So no need to repeat the check. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: drop extra getprop call during bootSam Ravnborg
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: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: drop prom version check in head_32.SSam Ravnborg
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: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: remove sun4c specific variables from head_32.SSam Ravnborg
This gives us back 7 pages... Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: Add back early sun4/sun4c detection so we can warn properly.David S. Miller
We need to do the check before we try to remap the kernel using SRMMU operations. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: Trivial removal of sun4c references in comments.David S. Miller
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: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: Remove sun4 and sun4c from enum sparc_cpu.David S. Miller
All the remaining references are trivially removed since we've just eliminated the final reference to sparc_cpu_model from assembler code in commit b7d96ce189564e661909fbf8df39d7358149885b ("sparc32: Remove sparc_cpu_model read from floppy interrupt handler.") Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-12sparc32: Remove sparc_cpu_model read from floppy interrupt handler.David S. Miller
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: David S. Miller <davem@davemloft.net>

2012-05-11sparc32: Restore SMP build and rectify sun4m NMI when non-SMP.David S. Miller
The non-SMP sun4m NMI handler was still accessing SUN4C registers. Fix that and share the sun4m NMI trap code between SMP and non-SMP cases. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-11sparc32: Kill asm/vac-ops.hDavid S. Miller

Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-11sparc32: Remove sun4c floppy assembler.David S. Miller
There were two blocks of code for the two ways to twiddle the terminal count pin in the AUXIO register, one for sun4c and one for sun4m. Kill the former. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-11sparc32: Put back SPARC_BRANCH.David S. Miller
It's needed for the floppy interrupt trap table patching. Signed-off-by: David S. Miller <davem@davemloft.net>

2012-05-11sparc: Convert some assembler over to linakge.h's ENTRY/ENDPROCDavid S. Miller
Use those, instead of doing it all by hand. Signed-off-by: David S. Miller <davem@davemloft.net>

2012-05-11sparc32: use inline versions of pgprot_noncached, pte_to_pgoff and pgoff_to_pteSam Ravnborg
We no longer have different versions of these so use a few simple static inline functions. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-05-11sparc32: drop btfixup for alloc_thread_info_node/free_thread_infoSam Ravnborg

2012-05-11sparc32: drop sun4c bits from head_32.SSam Ravnborg
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: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-05-11sparc32: drop sun4c user stack checking routineSam Ravnborg
With this we no longer do any run-time patchings of traps. So drop the function + macro to support this. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
