Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now.

/kernel/trunk/
Update page fault handlers to distinguish between different access modes that had caused the page fault.

Modify ia64 linker script to make compilation with gcc 4.1.x possible.
1420
6657 d 3 h
jermar
/kernel/trunk/
Upgrade toolchain to use gcc 4.1.1.
ia64 still cannot be built with combination of binutils 2.16.1 and gcc 4.1.x
1417

/kernel/trunk/generic/
Modify as_area_share() to accept destination area flags bitmask from the sender
(i.e. the sender can limit access mode to the shared area for the recipient).
Modify IPC_M_AS_AREA_SEND code to support this. Arguments for sender: arg1=as_area,
arg2=size, arg3=flags_mask.
The mechanism seems to work, but the page fault handlers need to be altered to
distinguish between faults under different access modes.

/kernel/trunk/generic/
Make implementation of condition variables compliant with their definition.
Signal operation must become a no-op if there is no thread in the wait operation.
Remove condvar_trywait() which has no meaning after this change.

Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount

/kernel/trunk/generic/src/synch/
Small fixes in futex.c.
PTE_GET_FRAME() returns frame address, not PFN.
Update comments.

/kernel/trunk/generic/
Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.
1411
6659 d 21 h
jermar
/kernel/trunk/
Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.

/kernel/trunk/arch/sparc64/
Modify sparc64 to choose optimal page size in each invocation of hw_map().
Use hw_map() to map keyboard device memory.
1409
6660 d 15 h

/kernel/trunk/generic/
Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.
1403

jermar
/kernel/trunk/generic/src/mm/
Fixes of the used_space management code.
Switch as_area_destroy() and as_area_resize() to use the used_space map.
as_area_steal() not switched as it will undergo further changes.

Fixed mips to compile with fb (missing hw_map).
Fixed mips hw virt/phys addresses of fb.
Moved fb_init to post_mm, because it needs malloc().

Add used_space_insert() and used_space_remove().
These are the alpha versions of functions that
will help to map used and unused portions of address
space areas. Currently unused, but many as_area operations
will be more efficient when the used space B+tree map
is used.
