31 6961 d 8 h jermar /SPARTAN/trunk/ Replace the deadlock-prone TLB shootdown algorithm with a deadlock-free implementation.
The implementation is a variant of the CMU TLB consistency algorithm.
Very inefficient implementation of a very inefficient (but correct) algorithm.		  
27 6963 d 2 h jermar /SPARTAN/trunk/ APIC changes and fixes.
Be more robust during MP configuration.

Do not use APIC ID as CPU_ID_ARCH anymore.
Changing APIC ID's is not a good idea.
Use dr0 register instead.		  
26 6965 d 10 h jermar /SPARTAN/trunk/ Code cleanup after arch_init() splitting.
Restore %ds and %es registers before iret.		  
25 6965 d 14 h jermar /SPARTAN/trunk/src/ Fix waitq_sleep_timeout() to call before_thread_runs() when handling timeout.  
22 6970 d 6 h jermar /SPARTAN/trunk/ Added before_thread_runs() to cope with TSS of user space tasks.  
19 6977 d 4 h jermar /SPARTAN/trunk/ Re-enable tests and fix include paths' in them.  
16 6977 d 8 h jermar /SPARTAN/trunk/ Switch from mm-based 'the' mechanism to macro-based 'cpu_private_data[CPU_ID_ARCH]' mechanism.
Added l_apic_id() and some other minor APIC changes.
Move gdtr to K_DATA_START section.
Move K_DATA_START section immediately behind K_TEXT_START section so that real-mode addresses work even with growing size of kernel code.		  
3 7028 d 6 h jermar /SPARTAN/trunk/src/ Minor change.  
2 7028 d 7 h jermar /SPARTAN/trunk/src/ Add ia64 and amd64 to config Makefile.  
1 7028 d 7 h jermar /SPARTAN/ Initial import
