* MIPS: DEC/SNI: O32 wrapper stack switching fixesMaciej W. Rozycki2014-05-132-23/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: delete non-required instances of include <linux/init.h>Paul Gortmaker2014-01-241-1/+0
| | | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

* MIPS: Kconfig: Rename several firmware related config symbols.Ralf Baechle2012-12-131-1/+1
| | | | | | | | | | | | With the upcoming merge of the ARC architecture there is a small likelyhood of conflicting use for the CONFIG_ARC config symbol. Rename it to CONFIG_FW_ARC. Also rename CONFIG_ARC32 to CONFIG_FW_ARC32, CONFIG_ARC64 to CONFIG_FW_ARC64. For consistence also rename CONFIG_SNIPROM to CONFIG_FW_SNIPROM and CONFIG_CFE to CONFIG_FW_CFE.

I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that.
