powerpc: Mark some variables in the page fault path __read_mostly

2010-02-03T06:39:48Z

Using perf to trace L1 dcache misses and dumping data addresses I found a few variables taking a lot of misses. Since they are almost never written, they should go into the __read_mostly section. Signed-off-by: Anton Blanchard Signed-off-by: Benjamin Herrenschmidt

powerpc/pseries: Add extended_cede_processor() helper function.

2009-11-24T03:33:03Z

This patch provides an extended_cede_processor() helper function which takes the cede latency hint as an argument. This hint is to be passed on to the hypervisor to cede to the corresponding state on platforms which support it.

powerpc/booke: Fix xmon single step on PowerPC Book-E

2009-10-27T05:42:40Z

Prior to the arch/ppc -> arch/powerpc transition, xmon had support for single stepping on 4xx boards. The functionality was lost when arch/ppc was removed. This patch restores single step support for 44x boards, and Book-E in general. Signed-off-by: Josh Boyer Signed-off-by: Benjamin Herrenschmidt

powerpc/4xx: Fix erroneous xmon warning on PowerPC 4xx

2009-09-24T05:31:49Z

The xmon code relies on MSR_RI being non-zero to indicate that an exception is recoverable. If it is not, it prints a warning message. However, the PowerPC 4xx cores do not have an MSR_RI bit and this warning is produced for every xmon event. This introduces an unrecoverable_excp function to determine if an exception is recoverable or not. This gets rid of the erroneous warnings on 4xx.

powerpc: Enable GCOV

2009-08-20T00:29:28Z

Make it possible to enable GCOV code coverage measurement on powerpc. Lightly tested on 64-bit, seems to work as expected. Signed-off-by: Michael Ellerman Signed-off-by: Benjamin Herrenschmidt

powerpc: Remaining 64-bit Book3E support

2009-08-20T00:25:11Z

This contains all the bits that didn't fit in previous patches :-) This includes the actual exception handlers assembly, the changes to the kernel entry, other misc bits and wiring it all up in Kconfig. Signed-off-by: Benjamin Herrenschmidt

powerpc: Add configurable -Werror for arch/powerpc

2009-06-16T04:15:45Z

Add the option to build the code under arch/powerpc with -Werror. The intention is to make it harder for people to inadvertantly introduce warnings in the arch/powerpc code. It needs to be configurable so that if a warning is introduced, people can easily work around it while it's being fixed. The option is a negative, ie. don't enable -Werror, so that it will be turned on for allyes and allmodconfig builds. The default is n, in the hope that developers will build with -Werror, that will probably lead to some build breaks, I am prepared to be flamed. It's not enabled for math-emu, which is a steaming pile of warnings. Signed-off-by: Michael Ellerman Signed-off-by: Benjamin Herrenschmidt
