ARM/io: Remove useless definition of mmiowb()

2019-04-08T10:59:53Z

ARM includes asm-generic/io.h, which provides a dummy definition of mmiowb() if one isn't already provided by the architecture. Remove the useless definition. Acked-by: Linus Torvalds Signed-off-by: Will Deacon

xen: don't include from and

2018-09-26T14:45:18Z

Nothing Xen specific in these headers, which get included from a lot of code in the kernel. So prune the includes and move them to the Xen-specific files that actually use them instead. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

block: remove ARCH_BIOVEC_PHYS_MERGEABLE

2018-09-26T14:45:11Z

Take the Xen check into the core code instead of delegating it to the architectures. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

xen: provide a prototype for xen_biovec_phys_mergeable in xen.h

2018-09-26T14:45:10Z

Having multiple externs in arch headers is not a good way to provide a common interface. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

arm: remove the unused BIOVEC_MERGEABLE define

block: simplify BIOVEC_PHYS_MERGEABLE

2018-09-24T18:33:54Z

Turn the macro into an inline, move it to blk.h and simplify the arch hooks a bit. Also rename the function to biovec_phys_mergeable as there is no need to shout. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

ARM: Implement pci_remap_cfgspace() interface

2017-04-24T18:53:13Z

The PCI bus specification (rev 3.0, 3.2.5 "Transaction Ordering and Posting") defines rules for PCI configuration space transactions ordering and posting, that state that configuration writes have to be non-posted transactions. Current ioremap interface on ARM provides mapping functions that provide "bufferable" writes transactions (ie ioremap uses MT_DEVICE memory type) aka posted writes, so PCI host controller drivers have no arch interface to remap PCI configuration space with memory attributes that comply with the PCI specifications for configuration space. Implement an ARM specific pci_remap_cfgspace() interface that allows to map PCI config memory regions with MT_UNCACHED memory type (ie strongly ordered - non-posted writes), providing a remap function that complies with PCI specifications for config space transactions.

arm, arm64: don't include blk_types.h in

No need for it - we only use struct bio_vec in prototypes and already have forward declarations for it. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe
