dma-mapping: use unsigned long for dma_attrs

2016-08-04T12:50:07Z

The dma-mapping core and the implementations do not change the DMA attributes passed by pointer. Thus the pointer can point to const data. However the attributes do not have to be a bitfield. Instead unsigned long will do fine: 1. This is just simpler. Both in terms of reading the code and setting attributes. Instead of initializing local attributes on the stack and passing pointer to it to dma_set_attr(), just set the bits. 2. It brings safeness and checking for const correctness because the attributes are passed by value.

treewide: replace obsolete _refok by __ref

2016-08-02T21:31:41Z

There was only one use of __initdata_refok and __exit_refok __init_refok was used 46 times against 82 for __ref. Those definitions are obsolete since commit 312b1485fb50 ("Introduce new section reference annotations tags: __ref, __refdata, __refconst") This patch removes the following compatibility definitions and replaces them treewide. /* compatibility defines */ #define __init_refok __ref #define __initdata_refok __refdata #define __exit_refok __ref I can also provide separate patches if necessary. (One patch per tree and check in 1 month or 2 to remove old definitions) [akpm@linux-foundation.org: coding-style fixes] Link: http://lkml.kernel.org/r/1466796271-3043-1-git-send-email-fabf@skynet.be Signed-off-by: Fabian Frederick Cc: Ingo Molnar Cc: Sam Ravnborg Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

powerpc/64: Move 64-bit probe_machine() to later in the boot process

2016-07-21T08:59:22Z

We no long need the machine type that early, so we can move probe_machine() to after the device-tree has been expanded. This will allow further consolidation. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Michael Ellerman

powerpc/mm: Move hash table ops to a separate structure

2016-07-21T08:59:09Z

Moving probe_machine() to after mmu init will cause the ppc_md fields relative to the hash table management to be overwritten. Since we have essentially disconnected the machine type from the hash backend ops, finish the job by moving them to a different structure. The only callback that didn't quite fix is update_partition_table since this is not specific to hash, so I moved it to a standalone variable for now. We can revisit later if needed.

powerpc/64: Move MMU backend selection out of platform code

2016-07-21T08:56:38Z

We move it into early_mmu_init() based on firmware features. For PS3, we have to move the setting of these into early_init_devtree(). Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Michael Ellerman

powerpc: Make ppc_md.{halt, restart} __noreturn

2016-07-14T11:12:06Z

powernv marks it's halt and restart calls as __noreturn. However, ppc_md does not have this annotation. Add the annotation to ppc_md, and then to every halt/restart function that is missing it. Additionally, I have verified that all of these functions do not return. Occasionally I have added a spin loop to be sure. Signed-off-by: Daniel Axtens Signed-off-by: Michael Ellerman

char/genrtc: remove powerpc support

2016-06-03T22:23:35Z

PowerPC is the last architecture using the GEN_RTC driver on some machines, but we can migrate them all to using the RTC_DRV_GENERIC driver instead now. This moves over the CONFIG_GEN_RTC option from drivers/char into arch/powerpc/platforms/Kconfig and makes it just select the replacement driver instead, for the only reason of not breaking existing defconfig and .config files that users may have.

powerpc/mm/hash: Add support for Power9 Hash

2016-05-01T08:32:40Z

PowerISA 3.0 adds a parition table indexed by LPID. Parition table allows us to specify the MMU model that will be used for guest and host translation. This patch adds support with SLB based hash model (UPRT = 0). What is required with this model is to support the new hash page table entry format and also setup partition table such that we use hash table for address translation. We don't have segment table support yet. In order to make sure we don't load KVM module on Power9 (since we don't have kvm support yet) this patch also disables KVM on Power9.
