2012-09-28ARM: 7541/1: Add ARM ERRATA 775420 workaroundSimon Horman
arm: Add ARM ERRATA 775420 workaround Workaround for the 775420 Cortex-A9 (r2p2, r2p6,r2p8,r2p10,r3p0) erratum. In case a date cache maintenance operation aborts with MMU exception, it might cause the processor to deadlock. This workaround puts DSB before executing ISB if an abort may occur on cache maintenance. Based on work by Kouei Abe and feedback from Catalin Marinas.

The OHCI fix has been reported a number of times and is a regression from 3.5, and the patch that causes the regression was on the way to the -stable trees before I was reminded (again) that this fix needed to get to your tree soon. The host controller bugfix was reported in older kernels as being pretty easy to trigger, and has been tested by Red Hat and their customers. Both have been in the usb-next branch in the -next tree for a while now, I just cherry-picked them out to get to you in time for the 3.6 release.

2012-09-27USB: Fix race condition when removing host controllersAlan Stern
This patch (as1607) fixes a race that can occur if a USB host controller is removed while a process is reading the /sys/kernel/debug/usb/devices file. The usb_device_read() routine uses the bus->root_hub pointer to determine whether or not the root hub is registered. The is not a valid test, because the pointer is set before the root hub gets registered and remains set even after the root hub is unregistered and deallocated. As a result, usb_device_read() or usb_device_dump() can access freed memory, causing an oops. The patch changes the test to use the hcd->rh_registered flag, which does get set and cleared at the appropriate times. It also makes sure to hold the usb_bus_list_lock mutex while setting the flag, so that usb_device_read() will become aware of new root hubs as soon as they are registered.

The 'enough' function is written to work with 'near' arrays only in that is implicitly assumes that the offset from one 'group' of devices to the next is the same as the number of copies. In reality it is the number of 'near' copies. So change it to make this number explicit. This bug makes it possible to run arrays without enough drives present, which is dangerous. It is appropriate for an -stable kernel, but will almost certainly need to be modified for some of them.

2012-09-26syscalls: add __NR_kcmp syscall to generic unistd.hMark Salter
Commit d97b46a64 ("syscalls, x86: add __NR_kcmp syscall" ) added a new syscall to support checkpoint restore. It is currently x86-only, but that restriction will be removed in a subsequent patch. Unfortunately, the kernel checksyscalls script had a bug which suppressed any warning to other architectures that the kcmp syscall was not implemented. A patch to checksyscalls is being tested in linux-next and other architectures are seeing warnings about kcmp being unimplemented. This patch adds __NR_kcmp to <asm-generic/unistd.h> so that kcmp is wired in for architectures using the generic syscall list.

Pull more networking fixes from David Miller: 1) Eric Dumazet discovered and fixed what turned out to be a family of bugs. These functions were using pskb_may_pull() which might need to reallocate the linear SKB data buffer, but the callers were not expecting this possibility. The callers have cached pointers to the packet header areas, and would need to reload them if we were to continue using pskb_may_pull(). So they could end up reading garbage. It's easier to just change these RAW4/RAW6/MIP6 routines to use skb_header_pointer() instead of pskb_may_pull(), which won't modify the linear SKB data area. 2) Dave Jone's syscall spammer caught a case where a non-TCP socket can call down into the TCP keepalive code. The case basically involves creating a raw socket with sk_protocol == IPPROTO_TCP, then calling setsockopt(sock_fd, SO_KEEPALIVE, ...) Fixed by Eric Dumazet. 3) Bluetooth devices do not get configured properly while being powered on, resulting in always using legacy pairing instead of SSP. Fix from Andrzej Kaczmarek. 4) Bluetooth cancels delayed work erroneously, put stricter checks in place. From Andrei Emeltchenko. 5) Fix deadlock between cfg80211_mutex and reg_regdb_search_mutex in cfg80211, from Luis R. Rodriguez. 6) Fix interrupt double release in iwlwifi, from Emmanuel Grumbach. 7) Missing module license in bcm87xx driver, from Peter Huewe. 8) Team driver can lose port changed events when adding devices to a team, fix from Jiri Pirko. 9) Fix endless loop when trying ot unregister PPPOE device in zombie state, from Xiaodong Xu. 10) batman-adv layer needs to set MAC address of software device earlier, otherwise we call tt_local_add with it uninitialized. 11) Fix handling of KSZ8021 PHYs, it's matched currently by KS8051 but that doesn't program the device properly.

2012-09-25lib/flex_proportions.c: fix corruption of denominator in flexible proportionsJan Kara
When racing with CPU hotplug, percpu_counter_sum() can return negative values for the number of observed events. This confuses fprop_new_period(), which uses unsigned type and as a result number of events is set to big *positive* number. From that moment on, things go pear shaped and can result e.g. in division by zero as denominator is later truncated to 32-bits. This bug causes a divide-by-zero oops in bdi_dirty_limit() in Borislav's 3.6.0-rc6 based kernel. Fix the issue by using a signed type in fprop_new_period(). That makes us bail out from the function without doing anything (mistakenly) thinking there are no events to age. That makes aging somewhat inaccurate but getting accurate data would be rather hard.

2012-09-25sb_edac: Avoid overflow errors at memory size calculationMauro Carvalho Chehab
Sandy bridge EDAC is calculating the memory size with overflow. Basically, the size field and the integer calculation is using 32 bits. More bits are needed, when the DIMM memories have high density. The net result is that memories are improperly reported there, when high-density DIMMs are used: EDAC DEBUG: in drivers/edac/sb_edac.c, line at 591: mc#0: channel 0, dimm 0, -16384 Mb (-4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800 EDAC DEBUG: in drivers/edac/sb_edac.c, line at 591: mc#0: channel 1, dimm 0, -16384 Mb (-4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800 As the number of pages value is handled at the EDAC core as unsigned ints, the driver shows the 16 GB memories at sysfs interface as 16760832 MB! The fix is simple: calculate the number of pages as unsigned 64-bits integer. After the patch, the memory size (16 GB) is properly detected: EDAC DEBUG: in drivers/edac/sb_edac.c, line at 592: mc#0: channel 0, dimm 0, 16384 Mb (4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800 EDAC DEBUG: in drivers/edac/sb_edac.c, line at 592: mc#0: channel 1, dimm 0, 16384 Mb (4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800 Cc: stable@kernel.org Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
