Bahadir Balban e8f002f879 Fixed most of userspace (mm0) for capability manipulation 2009-11-07 19:43:05 +02:00
Bahadir Balban d306d6b451 posix: Fixing mm0 mapping task pages incorrectly 
Modifying task_virt_to_page() so that it takes into account page
protections. If mm0 writes to a task page that is meant to be
read-only, (e.g. the zero page) the design is broken.

Every access to a task's page will take the page fault route,
and the page fault handler will return the page instead of 0.

Bahadir Balban 35a5dc4c92 Added userland support for exregs/read, mm0 slightly more graceful for illegal access 2009-11-05 15:56:01 +02:00
Bahadir Balban 7ba7a2e796 Added a simplified ascii_to_int() implementation. 
Removed dependency on hard-coded pager id. Pager id is now passed
as an environment string `pagerid' to tasks. Alternatively, this
could take space in the utcb of each task.
