MIPS: DEC/SNI: O32 wrapper stack switching fixes Commit 231a35d37293ab88d325a9cb94e5474c156282c0 [[MIPS] RM: Collected changes] broke DECstation support by introducing an incompatible copy of arch/mips/dec/prom/call_o32.S in arch/mips/fw/lib/, built unconditionally. The copy happens to land earlier of the two among the modules used in the link and is therefore chosen for the DECstation rather than the intended original. As a result random kernel data is corrupted because a pointer to the "%s" formatted output template is used as a temporary stack pointer rather than being passed down to prom_printf. This also explains why prom_printf still works, up to a point -- the next argument is the actual string to output so it works just fine as the output template until enough kernel data has been corrupted to cause a crash. This change adjusts the modified wrapper in arch/mips/fw/lib/call_o32.S to let callers request no stack switching by passing a null temporary stack pointer in $a1, reworks the DECstation callers to work with the updated interface and removes the old copy from arch/mips/dec/prom/call_o32.S. A few minor readability adjustments are included as well, most importantly O32_SZREG is now used throughout where applicable rather than hardcoded multiplies of 4 and $fp is used to access the argument save area as a more usual register to operate the stack with rather than $s0. Finally an update is made to the temporary stack space used by the SNI platform to guarantee 8-byte alignment as per o32 requirements. Signed-off-by: Maciej W.

MIPS: Whitespace cleanup. Having received another series of whitespace patches I decided to do this once and for all rather than dealing with this kind of patches trickling in forever. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

MIPS: Eleminate filenames from comments They tend to get not updated when files are moved around or copied and lack any obvious use. While at it zap some only too obvious comments and as per Shinya's suggestion, add a copyright header to extable.c.

[MIPS] RM: Collected changes - EISA support for non PCI RMs (RM200 and RM400-xxx). The major part is the splitting of the EISA and onboard ISA of the RM200, which makes the EISA bus on the RM200 look like on other RMs. - 64bit kernel support - system type detection is now common for big and little endian - moved sniprom code to arch/mips/fw - added call_o32 function to arch/mips/fw/lib, which uses a private stack for calling prom functions - fix problem with ISA interrupts, which makes using PIT clockevent possible Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
