grehan 8d87f5baaa Fix gdb issue where the i-cache was not being updated when a breakpoint ... was written into a user's address space. The fix is to modify uiomove_fromphys to sync the icache when an executable user-space page is written into. Alan Cox suggested that there should probably be a higher-level interface to this in the ptrace code, but agreed that this is an OK short-term solution. Files changed: pmap.h - declaration of pmap_page_executable() pmap_dispatch.c - pass through the page_executable call to the mmu object mmu_oea.c - implement the page_executable method by examining the PTE_EXEC field in the vm_page_t uio_machdep.c - in uiomove_fromphys(), if the op was a UIO_WRITE to user-space, and if the page is executable, sync the icache since this is at the least a breakpoint-write from gdb.
