MFppc64: Kernel sources for 64-bit PowerPC, along with build-system changes to keep 32-bit kernels compiling (build system changes for 64-bit kernels are coming later). Existing 32-bit PowerPC kernel configurations must be updated after this change to specify their architecture. 2010-07-13 05:32:19 +00:00			`#ifdef __powerpc64__`

Add a kdb show command to print arbitrary SPRs on PowerPC Summary: There is often a need at the debugger to print arbitrary special purpose registers (SPRs) on PowerPC. Using a rewritable asm stub, print any SPR provided on the command line. Note, as there is no checking in this, attempting to print a nonexistent SPR may cause a Program exception (illegal instruction, or boundedly undefined). Note also that this relies on the kernel text pages being writable. If in the future this is made not the case, this will need to be reworked.
