2008-02-19MN10300: Make the kernel jump into gdbstub on a BUGDavid Howells
Make the kernel jump into gdbstub (if configured) on a BUG with the register set from the BUG rather than interpolating another illegal instruction and leaving gdbstub's idea of the process counter in unsupported_syscall() where the original BUG was detected. With this patch, gdbstub reports a SIGABRT to the compiler and reports the program counter at the original BUG, allowing the execution state at the time of the BUG to be examined with GDB.

2008-02-19[MIPS] Handle I-cache coherency in flush_cache_range()Ralf Baechle
So far flush_cache_range() did't consider the I-cache largely because it did rarely ever matter to real world code. This was working primarily because normally code and data are don't share the same pages - with the exception of MIPS16 code which uses address constants embedded between the code. The following sequence of events may break the code: o MIPS16 executable being loaded o dynamic linker relocates the address constants embedded into the code: o Uses mprotect(2) to make code pages PROT_READ|PROT_WRITE o Performs the actual relocations by writing to the pages which likely are COW. Because no PROT_EXEC is set I-cache coherence will not be considered. o Uses mprotect(2) to switch code pages back to PROT_READ|PROT_EXEC. This results in a call to flush_cache_range() which also does not consider I-caches. o => executing the page just having been relocated may now result in the I-cache getting refilled with stale data from memory.
