2019-08-16ia64: remove support for the SGI SN2 platformChristoph Hellwig1-413/+0
The SGI SN2 (early Altix) is a very non-standard IA64 platform that was at the very high end of even IA64 hardware, and has been discontinued a long time ago. Remove it because there no upstream users left, and it has magic hooks all over the kernel.

2006-02-15[IA64-SGI] sn2 minor fixes and cleanupsJes Sorensen1-10/+4
General SN2 code cleanup: - Do not initialize global variables to zero - Use kzalloc instead of kmalloc+memset - Check kmalloc return values - Do not obfuscate spin lock calls - Remove some unused code - Various formatting cleanups Signed-off-by: Jes Sorensen <jes@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

2006-01-13[IA64-SGI] Fix sn_flush_device_kernel & spinlock initializationPrarit Bhargava1-16/+18
This patch separates the sn_flush_device_list struct into kernel and common (both kernel and PROM accessible) structures. As it was, if the size of a spinlock_t changed (due to additional CONFIG options, etc.) the sal call which populated the sn_flush_device_list structs would erroneously write data (and cause memory corruption and/or a panic). This patch does the following: 1. Removes sn_flush_device_list and adds sn_flush_device_common and sn_flush_device_kernel. 2. Adds a new SAL call to populate a sn_flush_device_common struct per device, not per widget as previously done. 3. Correctly initializes each device's sn_flush_device_kernel spinlock_t struct (before it was only doing each widget's first device).

2005-05-03[IA64-SGI] Altix only: Fix for sn_dma_flushMike Habeck1-1/+1
The following patch fixes a bug in the SGI Altix sn_dma_flush code. sn_dma_flush is broken in 2.6. The code isn't waiting for the DMA data to be flushed out of the PIC ASIC.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+379
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
