When invalidating entire TLBs on sparc64, make sure to also invalidate any (locked) global entries.
This fixes Ticket #21.
Fix a comment in start.S stating that the kernel installs a global entry for itself. All entries installed by the kernel
are local to some memory context. |

Add option to compile the sparc64 kernel without the TTE_CV bit support.
The bit is not used by default now.
Enabling it may theoretically lead to physical memory inconsistencies until code that
mitigates the problem is written. |

- Improve panic screen on data_access_exception
by dumping contents of DSFSR and DSFAR.
- Change the FHC enable interrupt code to only
set the IMAP_V bit. |

Small fixes.

sparc64 work.
- the syscall wrapper needs to use the "memory"
clobber specifier to prevent over-optimization.
- on sparc64, the user address space spans the whole
64-bit space and therefore the macro
USER_ADDRESS_SPACE_SIZE_ARCH, as it was defined,
overflows to 0
- stop using USER_ADDRESS_SPACE_SIZE_ARCH and define
MAX_HEAP_SIZE instead
- in our situation when kernel and user address spaces
are separate, the G (global) bit cannot be used
(there is no point in it anymore)
- add the DEBUG() macro to stdio.h; DEBUG() uses
SYS_IO and is a good debugging tool for getting
early userspace to work |

sparc64 update.
- Prototype userspace layer implementation that
at least relates to sparc64 and compiles cleanly.
- Fixes for kernel's preemptible_handler and code
related to running userspace.
- Enable userspace. Several dozen instructions
are now run in userspace! We are pretty near
the userspace milestone for sparc64. |

A lot of untested sparc64 stuff:
- Write ASID to hardware when a thread is about to run in userspace.
- Add userspace() and switch_to_userspace() functions.
- Handle special cases when the userspace spill/fill handler causes MMU trap.
- Resolve some TODOs in the existing sparc64 code.
- sparc64 has now C99 compliant header guards.
- Formatting and indentation fixes. |

sparc64 work.
- Convert interrupt_vector trap handler and some mm related trap handlers to
use preemptibe_handler(), which is essential for traps coming from userspace.
- Add fast_data_access_protection() handler. |
