Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.

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/
Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.

Added uspace call to enable/disable interrupts.

Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.

/kernel/trunk/arch/amd64/
Cleanup of amd64 code.

Add support for more then 2GB of address space for AMD64.
1051

Move amd64's ident_page_mapper() and page_fault() to page.h.

Remove WAKEUP_IPI stuff.
Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL.

Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.

palkovsky
/kernel/trunk/
Preliminary work on AMD userspace.

Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.
756

/kernel/trunk/
Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
755
6773 d 4 h
jermar
/kernel/trunk/
Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created.

break AMD64, will be fixed soon

Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.
684
6795 d 13 h
jermar
/kernel/trunk/
Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.
