[MIPS] Fix sparsemem support.

2006-06-05T23:15:20+00:00

    
Move memory_present() in arch/mips/kernel/setup.c. When using sparsemem
extreme, this function does an allocate for bootmem. This would always
fail since init_bootmem hasn't been called yet.
    
Move memory_present after free_bootmem. This only marks actual memory
ranges as present instead of the entire address space.

[MIPS] Fix 64-bit build for RM7000.

2006-06-05T23:15:19+00:00

    
RM7000 has 40-bit virtual / 36-bit physical address space.

[MIPS] Fix non-linear memory mapping on MIPS

2006-06-05T23:15:18+00:00

    
Fix the non-linear memory mapping done via remap_file_pages() -- it
didn't work on any MIPS CPU because the page offset clashing with
_PAGE_FILE and some other page protection bits which should have been left
zeros for this kind of pages.

[MIPS] Fix swap entry for MIPS32 36-bit physical address

2006-06-05T23:15:16+00:00

    
With 64-bit physical address enabled, 'swapon' was causing kernel oops on
Alchemy CPUs (MIPS32) because of the swap entry type field corrupting the
_PAGE_FILE bit in 'pte_low' field. So, switch to storing the swap entry in
'pte_high' field using all its bits except _PAGE_GLOBAL and _PAGE_VALID which
gives 25 bits for the swap entry offset.

[MIPS] Fix mprotect() syscall for MIPS32 w/36-bit physical address support

2006-06-05T23:15:15+00:00

    
Fix mprotect() syscall for MIPS32 CPUs with 36-bit physical address
support: pte_modify() macro didn't clear the hardware page protection bits
before modifying...

[MIPS] Fix declaration of smp_prepare_cpus() platform hook.

2006-06-05T23:15:12+00:00

    
A while ago prom_prepare_cpus was replaced by plat_prepare_cpus but
the declaration has stayed unchanged.

[MIPS] Fix instable BogoMIPS on multi-issue processors.

2006-06-05T23:15:10+00:00

Increase alignment of BogoMIPS loop to 8 bytes.  Having the delay loop
overlap cache line boundaries may cause instable delays.

[SPARC64]: Fix D-cache corruption in mremap

2006-06-02T00:47:25+00:00

If we move a mapping from one virtual address to another,
and this changes the virtual color of the mapping to those
pages, we can see corrupt data due to D-cache aliasing.

Check for and deal with this by overriding the move_pte()
macro.  Set things up so that other platforms can cleanly
override the move_pte() macro too.
