Comments in /drivers/misc/sgi-xp has been using '>>>' as a means to draw attention to something that needs to be done or considered. To avoid colliding with git rejects, '>>>' will now be replaced by '!!!' to indicate something to do, and by '???' to indicate something to be considered. Signed-off-by:

This series of patches adds a driver for the SGI UV GRU. The driver is still in development but it currently compiles for both x86_64 & IA64. All simple regression tests pass on IA64. Although features remain to be added, I'd like to start the process of getting the driver into the kernel. Additional kernel drivers will depend on services provide by the GRU driver. The GRU is a hardware resource located in the system chipset. The GRU contains memory that is mmaped into the user address space. This memory is used to communicate with the GRU to perform functions such as load/store, scatter/gather, bcopy, AMOs, etc. The GRU is directly accessed by user instructions using user virtual addresses. GRU instructions (ex., bcopy) use user virtual addresses for operands. The GRU contains a large TLB that is functionally very similar to processor TLBs. Because the external contains a TLB with user virtual address, it requires callouts from the core VM system when certain types of changes are made to the process page tables. There are several MMUOPS patches currently being discussed but none has been accepted into the kernel. The GRU driver is built using version V18 from Andrea Arcangeli. This patch: Contains the definitions of the hardware GRU data structures that are used by the driver to manage the GRU. [akpm@linux-foundation;org: export hpage_shift] Signed-off-by:

zap_vma_ptes() is intended to be used by drivers to unmap ptes assigned to the driver private vmas. This interface is similar to zap_page_range() but is less general & less likely to be abused. Needed by the GRU driver. Signed-off-by:
