2008-02-21Hibernation: Handle DEBUG_PAGEALLOC on x86Rafael J. Wysocki
Make hibernation work with CONFIG_DEBUG_PAGEALLOC set on x86, by checking if the pages to be copied are marked as present in the kernel mapping and temporarily marking them as present if that's not the case. No functional modifications are introduced if CONFIG_DEBUG_PAGEALLOC is unset. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Len Brown <len.brown@intel.com>

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.
