2010-10-29MIPS: Octeon: Apply CN63XXP1 errata workarounds.David Daney1-0/+1
The CN63XXP1 needs a couple of workarounds to ensure memory is not written in unexpected ways. All PREF with hints in the range 0-4,6-24 are replaced with PREF 28. We pass a flag to the assembler to cover compiler generated code, and patch uasm for the dynamically generated code. The write buffer threshold is reduced to 4.

2010-10-29MIPS: Get rid of branches to .subsections.Ralf Baechle1-3/+0
It was a nice optimization - on paper at least. In practice it results in branches that may exceed the maximum legal range for a branch. We can fight that problem with -ffunction-sections but -ffunction-sections again is incompatible with -pg used by the function tracer. By rewriting the loop around all simple LL/SC blocks to C we reduce the amount of inline assembler and at the same time allow GCC to often fill the branch delay slots with something sensible or whatever else clever optimization it may have up in its sleeve. With this optimization gone we also no longer need -ffunction-sections, so drop it. This optimization was originally introduced in 2.6.21, commit 5999eca25c1fd4b9b9aca7833b04d10fe4bc877d (linux-mips.org) rsp. f65e4fa8e0c6022ad58dc88d1b11b12589ed7f9f (kernel.org).

This patch is based on previous work by Sony and Himanshu Chauhan. I have done some cleanup and implemented JProbes and KRETPROBES. The KRETPROBES part is pretty much copied verbatim from powerpc. A possible future enhance might be to factor out the common code.

Conflicts: arch/powerpc/Makefile
2010-08-03kbuild: allow assignment to {A,C,LD}FLAGS_MODULE on the command lineSam Ravnborg1-2/+4
It is now possible to assign options to AS, CC and LD on the command line - which is only used when building modules. {A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile in the arch makefiles, thus users had no way to specify additional options to AS, CC, LD when building modules without overriding the original value. Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE that is used by arch specific files and free up {A,C,LD}FLAGS_MODULE so they can be assigned on the command line. All arch Makefiles that used the old variables has been updated. Note: Previously we had a MODFLAGS variable for both AS and CC. But in favour of consistency this was dropped. So in some cases arch Makefile has one assignmnet replaced by two assignmnets. Note2: MODFLAGS was not documented and is dropped without any notice. I do not expect much/any breakage from this.
