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:

Solves http://bugzilla.kernel.org/show_bug.cgi?id=11127 The old rtc.c driver did it and some drivers (like rtc-sh) do it in their release function, though they should not -- because they should provide the irq_set_state op and the rtc framework itself should care about it. This patch makes it do so. I am aware that some drivers, like rtc-sh, handle userspace PIE sets in their ioctl op (instead of having the framework call the op), exporting the irq_set_state op at the same time. The logic in rtc_irq_set_state should make sure it doesn't matter and the driver should not need to care stopping periodic interrupts in its release routine any more. The correct way, in my opinion, should be this: 1) The driver provides the irq_set_state op and does not care closing the interrupts in its release op. 2) If the driver does not provide the op and handles PIE in the ioctl op, it's reponsible for closing them in its release op. 3) Something similar for other IRQs, like UIE -- if there's no in-kernel API like irq_set_state, handle it in ioctl and release ops. The framework will be responsible either for everything or for nothing. (This will probably change later.) Signed-off-by:

Writes to the cmap fifo while the display is blanked caused cmap FIFO timeout messages and a wrong colormap. To avoid this the driver now maintains a colormap in memory and updates the colormap after the display is unblanked. Signed-off-by:
