When allocating a cappage, allocate a shadow object. (capfree): Really free CAPPAGE if there is another page available. If freeing CAPPAGE, unlink DESC and update DESC->CAP to reflect that the page has been deallocated, deallocate the shadow, and deallocate CAPPAGE. * exceptions.c (exception_thread): Print IP when a fault cannot be resolved. * mmap.c (mmap): Cast addr to a uintptr_t to elide warning. ruth/ 2007-11-22 Neal H. Walfield <neal@gnu.org> * ruth.c (main): Update uses of stroage_alloc to its new interface.

2007-11-19 Neal H. Walfield <neal@gnu.org> * Makefile.am (includehurd_HEADERS): Add exceptions.h. * headers.m4: Link $(BUILDIR)/include/hurd/exceptions.h to exceptions.h. * exceptions.h: New file. viengoos/ 2007-11-19 Neal H. Walfield <neal@gnu.org> * thread.h (struct thread): Add fields have_exception and exception. (UTCB_AREA_SIZE): Provide space for two UTCBs. * thread.c: Include <hurd/exceptions.h>. (thread_create_in): For each thread that we allocate, allocate two consecutive l4 thread ids. (thread_commission): Initialize the main thread and the exception thread. (thread_decommission): Destroy both the main thread and the exception thread. * rm.h: Add RM_exception_collect. (rm_method_id_string): Handle RM_exception_collect. (exception_collect): New RPC method. * server.c: Include <hurd/exceptions.h>. (server_loop): If FROM is the exception thread, look up the thread object using the main thread id. Propagate any fault to the exception thread. If not immediately successful, save the message in THREAD->EXCEPTION and set THREAD->HAVE_EXCEPTION. Implement the exception_collect method. (DEBUG): Also print the method number. libhurd-mm/ 2007-11-19 Neal H. Walfield <neal@gnu.org> * Makefile.am (libhurd_mm_a_SOURCES): Add exceptions.h, exceptions.c, pager.h, pager.c, anonymous.h and anonymous.c. * headers.m4: Link $(BUILDDIR)/include/hurd/pager.h to pager.h. Link $(BUILDDIR)/include/hurd/anonymous.h to anonymous.h. * mm-init.c: Include "exceptions.h". (mm_init): Call exception_handler_init. * pager.h: Completely rewrite. * pager.c: Likewise. * anonymous.h: Likewise. * anonymous.c: Likewise. * exceptions.h: New file. * exceptions.c: Likewise. * mmap.c: Include <hurd/anonymous.h>. (mmap): Rewrite to use an anonymous pager.
