Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[SPARC64]: Fix system type in /proc/cpuinfo and remove bogus OBP check. Report 'sun4v' when appropriate in /proc/cpuinfo Remove all the verifications of the OBP version string. Just make sure it's there, and report it raw in the bootup logs and via /proc/cpuinfo. Signed-off-by: David S. Miller <davem@davemloft.net>

[SPARC64]: Rewrite bootup sequence. Instead of all of this cpu-specific code to remap the kernel to the correct location, use portable firmware calls to do this instead. What we do now is the following in position independant assembler: chosen_node = prom_finddevice("/chosen"); prom_mmu_ihandle_cache = prom_getint(chosen_node, "mmu"); vaddr = 4MB_ALIGN(current_text_addr()); prom_translate(vaddr, &paddr_high, &paddr_low, &mode); prom_boot_mapping_mode = mode; prom_boot_mapping_phys_high = paddr_high; prom_boot_mapping_phys_low = paddr_low; prom_map(-1, 8 * 1024 * 1024, KERNBASE, paddr_low); and that replaces the massive amount of by-hand TLB probing and programming we used to do here. The new code should also handle properly the case where the kernel is mapped at the correct address already (think: future kexec support). Consequently, the bulk of remap_kernel() dies as does the entirety of arch/sparc64/prom/map.S We try to share some strings in the PROM library with the ones used at bootup, and while we're here mark input strings to oplib.h routines with "const" when appropriate. There are many more simplifications now possible. For one thing, we can consolidate the two copies we now have of a lot of cpu setup code sitting in head.S and trampoline.S. This is a significant step towards CONFIG_DEBUG_PAGEALLOC support. Signed-off-by: David S. Miller <davem@davemloft.net>

[SPARC64]: Detect sun4v early in boot process. We look for "SUNW,sun4v" in the 'compatible' property of the root OBP device tree node. Protect every %ver register access, to make sure it is not touched on sun4v, as %ver is hyperprivileged there. Lock kernel TLB entries using hypervisor calls instead of calls into OBP.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[SPARC64]: Rewrite bootup sequence. Instead of all of this cpu-specific code to remap the kernel to the correct location, use portable firmware calls to do this instead. What we do now is the following in position independant assembler: chosen_node = prom_finddevice("/chosen"); prom_mmu_ihandle_cache = prom_getint(chosen_node, "mmu"); vaddr = 4MB_ALIGN(current_text_addr()); prom_translate(vaddr, &paddr_high, &paddr_low, &mode); prom_boot_mapping_mode = mode; prom_boot_mapping_phys_high = paddr_high; prom_boot_mapping_phys_low = paddr_low; prom_map(-1, 8 * 1024 * 1024, KERNBASE, paddr_low); and that replaces the massive amount of by-hand TLB probing and programming we used to do here. The new code should also handle properly the case where the kernel is mapped at the correct address already (think: future kexec support). Consequently, the bulk of remap_kernel() dies as does the entirety of arch/sparc64/prom/map.S We try to share some strings in the PROM library with the ones used at bootup, and while we're here mark input strings to oplib.h routines with "const" when appropriate. There are many more simplifications now possible. For one thing, we can consolidate the two copies we now have of a lot of cpu setup code sitting in head.S and trampoline.S.

[SPARC64]: Use ASI_SCRATCHPAD address 0x0 properly. This is where the virtual address of the fault status area belongs. To set it up we don't make a hypervisor call, instead we call OBP's SUNW,set-trap-table with the real address of the fault status area as the second argument.
