2020-10-07x86/platform/uv: Update Copyrights to conform to HPE standardsMike Travis1-0/+1
Add Copyrights to those files that have been updated for UV5 changes. Signed-off-by: Mike Travis <[email protected]> Signed-off-by: Borislav Petkov <[email protected]> Link: https://lkml.kernel.org/r/[email protected]
2020-10-07drivers/misc/sgi-xp: Adjust references in UV kernel modulesMike Travis1-2/+2
Remove the define is_uv() is_uv_system and just use the latter as is. This removes a conflict with a new symbol in the generated uv_mmrs.h file (is_uv()).

2019-08-16misc/sgi-xp: remove SGI SN2 supportChristoph Hellwig1-6/+2
Note this also marks xp broken on ia64 now, as the UV support, which was disable in generic kernels before actually never compiled due to undefined uv_gpa_to_soc_phys_ram and uv_gpa_in_mmr_space symbols since at least commit c2c9f1157414 ("x86: uv: update XPC to handle updated BIOS interface").

2017-05-28sgi-xp: Use designated initializersKees Cook1-29/+7
Prepare to mark sensitive kernel structures for randomization by making sure they're using designated initializers. In this case, no initializers are needed (they can be NULL initialized and callers adjusted to check for NULL, which is more efficient than an indirect call).

2009-04-21sgi-xp/sgi-gru: allow modules to load on non-uv systemsRobin Holt1-6/+6
For an upcoming distro release, we need to have the xp kernel module loadable even when not on UV equipment. The xpc module will not load. This will allow one set of modules dependent upon xp to work on either UV or non-UV equipment.
