2013-04-27T20:58:36Z

Pull ARM SoC fix from Olof Johansson: "A late-arriving fix for musb on OMAP4, resolving an issue where the musb IP won't be clocked and thus not functional. Small in scope, most of the lines changed is a longish comment." * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: OMAP4: hwmod data: make 'ocp2scp_usb_phy_phy_48m" as the main clock

vm: add no-mmu vm_iomap_memory() stub

2013-04-27T20:25:38Z

I think we could just move the full vm_iomap_memory() function into util.h or similar, but I didn't get any reply from anybody actually using nommu even to this trivial patch, so I'm not going to touch it any more than required. Here's the fairly minimal stub to make the nommu case at least potentially work. It doesn't seem like anybody cares, though. Signed-off-by: Linus Torvalds

From Tony Lindgren: One MUSB regression fix that I forgot to send earlier. Without this MUSB no longer works on omap4 based devices. * tag 'omap-for-v3.9-rc6/fixes-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP4: hwmod data: make 'ocp2scp_usb_phy_phy_48m" as the main clock Signed-off-by: Olof Johansson

Pull media fixes from Mauro Carvalho Chehab: "Two driver fixes. One avoids reading any file at a system with a cx25821 board (fortunately, this is not a common device). The other one prevents reading after a buffer with ISDB-T devices based on mb86a20s." * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: [media] cx25821: do not expose broken video output streams [media] mb86a20s: Fix estimate_rate setting

Merge branch 'fixes-3.9-late' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

2013-04-26T15:05:01Z

Pull late parisc fixes from Helge Deller: "I know it's *very* late in the 3.9 release cycle, but since there aren't that many people testing the parisc linux kernel, a few (for our port) critical issues just showed up a few days back for the first time. What's in it? - add missing __ucmpdi2 symbol, which is required for btrfs on 32bit kernel. - change kunmap() macro to static inline function. This fixes a debian/gcc-4.4 build error. - add locking when doing PTE updates. This fixes random userspace crashes. - disable (optional) -mlong-calls compiler option for modules, else modules can't be loaded at runtime. - a smart patch by Will Deacon which fixes 64bit put_user() warnings on 32bit kernel." * 'fixes-3.9-late' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: use spin_lock_irqsave/spin_unlock_irqrestore for PTE updates parisc: disable -mlong-calls compiler option for kernel modules parisc: uaccess: fix compiler warnings caused by __put_user casting parisc: Change kunmap macro to static inline function parisc: Provide __ucmpdi2 to resolve undefined references in 32 bit builds.

efivars: only check for duplicates on the registered list

2013-04-26T15:02:03Z

variable_is_present() accesses '__efivars' directly, but when called via gsmi_init() Michel reports observing the following crash, BUG: unable to handle kernel NULL pointer dereference at (null) IP: variable_is_present+0x55/0x170 Call Trace: register_efivars+0x106/0x370 gsmi_init+0x2ad/0x3da do_one_initcall+0x3f/0x170 The reason for the crash is that '__efivars' hasn't been initialised nor has it been registered with register_efivars() by the time the google EFI SMI driver runs. The gsmi code uses its own struct efivars, and therefore, a different variable list. Fix the above crash by passing the registered struct efivars to variable_is_present(), so that we traverse the correct list.

TTY: fix atime/mtime regression

2013-04-26T14:59:23Z

In commit b0de59b5733d ("TTY: do not update atime/mtime on read/write") we removed timestamps from tty inodes to fix a security issue and waited if something breaks. Well, 'w', the utility to find out logged users and their inactivity time broke. It shows that users are inactive since the time they logged in. To revert to the old behaviour while still preventing attackers to guess the password length, we update the timestamps in one-minute intervals by this patch.
