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://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc: (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() ... | ||||

| * | sparc64: ldc_connect() should not return EINVAL when handshake is in progress. | Sowmini Varadhan | 2014-08-05 | 1 | -1/+1 |
| | | | | | | | | | | | | | | The LDC handshake could have been asynchronously triggered after ldc_bind() enables the ldc_rx() receive interrupt-handler (and thus intercepts incoming control packets) and before vio_port_up() calls ldc_connect(). If that is the case, ldc_connect() should return 0 and let the state-machine progress.

| * | hlist: drop the node parameter from iterators | Sasha Levin | 2013-02-28 | 1 | -2/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually.

| * | SPARC: drivers: remove __dev* attributes. | Greg Kroah-Hartman | 2013-01-04 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand. Cc: Bill Pemberton <wfp5p@virginia.edu> Cc: "David S.

| * | sparc/ldc: remove IRQF_SAMPLE_RANDOM which is now a no-op | Theodore Ts'o | 2012-07-19 | 1 | -4/+2 |
| | | | | | | | | | | | | | With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a no-op; interrupt randomness is now collected unconditionally in a very low-overhead fashion; see commit 775f4b297b. The IRQF_SAMPLE_RANDOM flag was scheduled to be removed in 2009 on the feature-removal-schedule, so this patch is preparation for the final removal of this flag.
