* x86: bios_uv.c: uv_systab should be staticJaswinder Singh Rajput2008-12-291-1/+1
| | | | | | | | | | Impact: cleanup, reduce kernel size a bit, avoid sparse warning Fixes sparse warning: arch/x86/kernel/bios_uv.c:28:18: warning: symbol 'uv_systab' was not declared. Should it be static? Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* sgi-xp: xpc needs to pass the physical address, not virtualRuss Anderson2008-12-161-3/+1
| | | | | | | | | | | | | | Impact: fix crash xpc needs to pass the physical address, not virtual. Testing uncovered this problem. The virtual address happens to work most of the time due to the way bios was masking off the node bits. Passing the physical address makes it work all of the time.

* x86, uv: use consistent names for region size and conherence id on x86 and ia64Russ Anderson2008-10-221-4/+4
| | | | | | | | | | Use consistent names for region size and conherence id on x86 and ia64. The SGI xp drivers are used on both ia64 and x86. Using the same names (sn_coherency_id, sn_region_size) simplies the driver code. Signed-off-by: Russ Anderson <rja@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86 BIOS interface for RTC on SGI UVRuss Anderson2008-07-181-0/+48
Real-time code needs to know the number of cycles per second on SGI UV. The information is provided via a run time BIOS call. This patch provides the linux side of that interface. This is the first of several run time BIOS calls to be defined in uv/bios.h and bios_uv.c. Note that BIOS_CALL() is just a stub for now. The bios side is being worked on.
