1823 6521 d 1 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.		  
1822 6521 d 5 h jermar /trunk/ sparc64 work.
1. Formatting fixes.
2. When writing to DMMU ASI's, simple membar() can be used in place of flush().
3. Substantial changes in the way the TLB is taken over.
4. Remove unneeded functions.

This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi
processor.

Note that 3. needs further work as the current implementation depends on the fact
that the compiler will use registers for local variables in take_over_tlb_and_tt().
Rewrite of that function into assembly is to follow.

1803 6536 d 16 h decky /trunk/ fix critical bug  
1802 6536 d 16 h decky /trunk/ cleanup and unify the build system

1800 6536 d 17 h decky /trunk/boot/arch/ppc64/loader/ sync ppc64 with ppc32  
1799 6536 d 17 h decky /trunk/boot/arch/ppc32/loader/ fix typo  
1798 6536 d 17 h decky /trunk/uspace/ make uspace compile for ppc64  
1797 6536 d 17 h decky /trunk/uspace/ dummy Sparc64 uspace support (it just compiles)  
1796 6536 d 17 h decky /trunk/boot/tools/ia64/ new place for vmaxlma  
1795 6536 d 17 h decky /trunk/contrib/ remove orphaned directory  
1794 6536 d 17 h decky /trunk/ move contrib from kernel/ to /
update Sparc64 toolchain to use Binutils 2.17 (neeeded for linking uspace)		  
1793 6539 d 5 h jermar /trunk/kernel/ Change hw_map() on sparc64 to use virtual addresses that are
beyond the end of physical memory. It is beneficial in two
ways: first, physical memory is no longer being wasted by
otherwise necessary calls to frame_alloc() and, second,
virtual addresses for devices are now correctly allocated
and do not overlap with the 4M TLB-locked mapping for
kernel text and data.		  
1792 6539 d 19 h jermar /trunk/ Move functionality of tlb_arch_init() to take_over_tlb_and_tt().
Call take_over_tlb_and_tt() very early after the kernel starts
executing.		  
1791 6539 d 21 h jermar /trunk/boot/arch/sparc64/loader/ Switch to identically mapped stack during boot.
Put stack related and register related macros to dedicated
header files.
