From: Linus Torvalds Date: Sat, 2 Mar 2013 15:44:16 +0000 (-0800) Subject: Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus X-Git-Tag: v3.9-rc1~26 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=aebb2afd5420c860b7fbc3882a323ef1247fbf16;p=profile%2Fcommon%2Fkernel-common.git Merge branch 'upstream' of git://git.linux-mips.org/ralf/upstream-linus Pull MIPS updates from Ralf Baechle: o Add basic support for the Mediatek/Ralink Wireless SoC family. o The Qualcomm Atheros platform is extended by support for the new QCA955X SoC series as well as a bunch of patches that get the code ready for OF support. o Lantiq and BCM47XX platform have a few improvements and bug fixes. o MIPS has sent a few patches that get the kernel ready for the upcoming microMIPS support. o The rest of the series is made up of small bug fixes and cleanups that relate to various parts of the MIPS code. The biggy in there is a whitespace cleanup. After I was sent another set of whitespace cleanup patches I decided it was the time to clean the whitespace "issues" for once and and that touches many files below arch/mips/. Fix up silly conflicts, mostly due to whitespace cleanups. * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (105 commits) MIPS: Quit exporting kernel internel break codes to uapi/asm/break.h MIPS: remove broken conditional inside vpe loader code MIPS: SMTC: fix implicit declaration of set_vi_handler MIPS: early_printk: drop __init annotations MIPS: Probe for and report hardware virtualization support.
