Pull sparc updates from David Miller: 1) Move to 4-level page tables on sparc64 and support up to 53-bits of physical addressing. Kernel static image BSS size reduced by several megabytes. 2) M6/M7 cpu support, from Allan Pais. 3) Move to sparse IRQs, handle hypervisor TLB call errors more gracefully, and add T5 perf_event support. From Bob Picco. 4) Recognize cdroms and compute geometry from capacity in virtual disk driver, also from Allan Pais. 5) Fix memset() return value on sparc32, from Andreas Larsson. 6) Respect gfp flags in dma_alloc_coherent on sparc32, from Daniel Hellstrom. 7) Fix handling of compound pages in virtual disk driver, from Dwight Engen. 8) Fix lockdep warnings in LDC layer by moving IRQ requesting to ldc_alloc() from ldc_bind(). 9) Increase boot string length to 1024 bytes, from Dave Kleikamp. * git:// (31 commits) sparc64: Fix lockdep warnings on reboot on Ultra-5 sparc64: Increase size of boot string to 1024 bytes sparc64: Kill unnecessary tables and increase MAX_BANKS. sparc64: sparse irq sparc64: Adjust vmalloc region size based upon available virtual address bits. sparc64: Increase MAX_PHYS_ADDRESS_BITS to 53. sparc64: Use kernel page tables for vmemmap. sparc64: Fix physical memory management regressions with large max_phys_bits. sparc64: Adjust KTSB assembler to support larger physical addresses. sparc64: Define VA hole at run time, rather than at compile time. sparc64: Switch to 4-level page tables. sparc64: Fix reversed start/end in flush_tlb_kernel_range() sparc64: Add vio_set_intr() to enable/disable Rx interrupts vio: fix reuse of vio_dring slot sunvdc: limit each sg segment to a page sunvdc: compute vdisk geometry from capacity sunvdc: add cdrom and v1.1 protocol support sparc: VIO protocol version 1.6 sparc64: Fix hibernation code refrence to PAGE_OFFSET. sparc64: Move request_irq() from ldc_bind() to ldc_alloc() ...
2014-10-09nosave: consolidate __nosave_{begin,end} in <asm/sections.h>Geert Uytterhoeven1-3/+1
The different architectures used their own (and different) declarations: extern __visible const void __nosave_begin, __nosave_end; extern const void __nosave_begin, __nosave_end; extern long __nosave_begin, __nosave_end; Consolidate them using the first variant in <asm/sections.h>.

2014-09-26sparc64: Fix hibernation code refrence to PAGE_OFFSET.David S. Miller1-2/+2
We changed PAGE_OFFSET to be a variable rather than a constant, but this reference here in the hibernate assembler got missed. Signed-off-by: David S. Miller <>
2013-03-20sparc64: Hibernation supportTkhai Kirill3-0/+176
This patch adds CONFIG_HIBERNATION support for sparc64 architecture. The suspend function is the same as on another platforms. The restore function uses Bypass feature of MMU which allows to make the process more comfortable and plesant.
