From: Linus Torvalds Date: Fri, 3 Jul 2015 23:02:25 +0000 (-0700) Subject: Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5fc835284d45a10a181b5c3f149a701e0391d1b2;p=openwrt%2Fstaging%2Fblogic.git Merge tag 'for_linus' of git://git./linux/kernel/git/mst/vhost Pull virtio/vhost cross endian support from Michael Tsirkin: "I have just queued some more bugfix patches today but none fix regressions and none are related to these ones, so it looks like a good time for a merge for -rc1. The motivation for this is support for legacy BE guests on the new LE hosts. There are two redeeming properties that made me merge this: - It's a trivial amount of code: since we wrap host/guest accesses anyway, almost all of it is well hidden from drivers. - Sane platforms would never set flags like VHOST_CROSS_ENDIAN_LEGACY, and when it's clear, there's zero overhead (as some point it was tested by compiling with and without the patches, got the same stripped binary). Maybe we could create a Kconfig symbol to enforce the second point: prevent people from enabling it eg on x86. I will look into this" * tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost: virtio-pci: alloc only resources actually used. macvtap/tun: cross-endian support for little-endian hosts vhost: cross-endian support for legacy devices virtio: add explicit big-endian support to memory accessors vhost: introduce vhost_is_little_endian() helper vringh: introduce vringh_is_little_endian() helper macvtap: introduce macvtap_is_little_endian() helper tun: add tun_is_little_endian() helper virtio: introduce virtio_is_little_endian() helper --- 5fc835284d45a10a181b5c3f149a701e0391d1b2
