sparc64: provide smp_send_pull_timers() implementation

2009-04-23T19:02:28+00:00

add sys_null_call() to enable system call overhead tracing

2009-03-02T21:16:35+00:00

A simple noop system call to record kernel entry and exit
times.

sparc: force resched on IPI

2008-05-01T23:15:25+00:00

This replicates 1a229e67e4cf08a539fc558d017a95ff03705ac5 for sparc64.

This is what happens:
	smp_send_reschedule()
	-> smp_receive_signal() (smp.c)
	~~> IPI
	~~> xcall_receive_signal (ultra.S)
	~~> soft interrupt (ttable.S)
	-> smp_receive_signal_client (smp.c)
	-> set_tsk_need_resched()

sparc64: include LITMUS syscalls

2008-05-01T20:58:48+00:00

add LITMUS syscalls in jump table and unistd.h

sparc64: enable LITMUS configuration options

[SPARC64]: Partially revert "Constify function pointer tables."

2008-01-24T05:32:04+00:00

This partially reverts 872e2be7c4056496c2871bd9b0f2fae6c374fe47
(Constify function pointer tables.)

The solaris/socksys.c transformation wasn't valid:

arch/sparc64/solaris/socksys.c:192: error: assignment of read-only variable ‘socksys_file_ops’
arch/sparc64/solaris/socksys.c:195: error: assignment of read-only variable ‘socksys_file_ops’
arch/sparc64/solaris/socksys.c:196: error: assignment of read-only variable ‘socksys_file_ops’

Fix following Section mismatch warning in sparc64:

The pci_* were all missing __init annotations.
For the vio.c case it was a function with a wrong annotation which was removed.

[SPARC64]: Fix hypervisor TLB operation error reporting.

2008-01-17T14:26:55+00:00

1) Trap level wasn't being passed down properly, we need to
   move it from %l4 into the correct outgoing arg register.

2) Although the TPC often provides the most direct clue, we
   have the caller PC so we should provide that as well.
