227 6920 d 21 h jermar /SPARTAN/trunk/ Add couple of assertions CPU != NULL.

Change type of nrdy from int to count_t.

Rewrite halt() to avoid page fault when CPU == NULL.		  
226 6920 d 21 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.		  
223 6921 d 2 h jermar /SPARTAN/trunk/ Preemption work.
Instrument spinlock functions with preemption_disable() and preemption_enable() calls.		  
221 6921 d 3 h jermar /SPARTAN/trunk/ Preemption work.
Define PREEMPTION_DISABLED macro.
This macro determines the level of preemptivity (0 = preemption enabled, THE->preemption_disabled = no preemption inside spinlock, 1 = preemption disabled).
Reformulate preemption code in clock.c to consider PREEMPTION_DISABLED.		  
220 6921 d 4 h vana /SPARTAN/trunk/ Universal exception handler and all exceptions routine to call it added  
219 6921 d 11 h palkovsky /SPARTAN/trunk/ Fixed bad type in frame.c.
Amd64 prints banner.		  
216 6921 d 12 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
214 6921 d 14 h vana /SPARTAN/trunk/src/  
213 6921 d 14 h jermar /SPARTAN/trunk/ Add some comments.  
212 6921 d 14 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
210 6921 d 14 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
208 6921 d 23 h palkovsky /SPARTAN/trunk/ arch_pre_init_mm now working.  
207 6922 d 0 h decky /SPARTAN/trunk/ separated stack mapping  
206 6922 d 1 h palkovsky /SPARTAN/trunk/ Better types for ia32 drivers, so that they can be reused in amd64.
Build script cleanup amd64.
New code / not working yet / in amd64.		  
205 6922 d 2 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().		  
202 6922 d 13 h palkovsky /SPARTAN/trunk/src/lib/ Fixed bad types in memsetw.  
200 6922 d 14 h palkovsky /SPARTAN/trunk/ Added putchar to AMD  
198 6922 d 14 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.		  
197 6922 d 16 h palkovsky /SPARTAN/trunk/ Context-save/restore in AMD64  
195 6922 d 16 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option
