The v6 and v7 implementations of flush_kern_dcache_area do not align the passed MVA to the size of a cacheline in the data cache. If a misaligned address is used, only a subset of the requested area will be flushed. This has been observed to cause failures in SMP boot where the secondary_data initialised by the primary CPU is not cacheline aligned, causing the secondary CPUs to read incorrect values for their pgd and stack pointers. This patch ensures that the base address is cacheline aligned before flushing the d-cache.

sanity_check_meminfo walks over the registered memory banks and attempts to split banks across lowmem and highmem when they would otherwise overlap with the vmalloc space. When SPARSEMEM is used, there are two potential problems that occur when the virtual address of the start of a bank is equal to vmalloc_min. 1.) The end of lowmem is calculated as __pa(vmalloc_min - 1) + 1. In the above scenario, this will give the end address of the previous bank, rather than the actual bank we are interested in. This value is later used as the memblock limit and artificially restricts the total amount of available memory. 2.) The checks to determine whether or not a bank belongs to highmem or not only check if __va(bank->start) is greater or less than vmalloc_min. In the case that it is equal, the bank is incorrectly treated as lowmem, which hoses the vmalloc area. This patch fixes these two problems by checking whether the virtual start address of a bank is >= vmalloc_min and then calculating lowmem_end by finding the virtual end address of the highest lowmem bank.

In commit eb33575c ("[ARM] Double check memmap is actually valid with a memmap has unexpected holes V2"), a new function, memmap_valid_within, was introduced to mmzone.h so that holes in the memmap which pass pfn_valid in SPARSEMEM configurations can be detected and avoided. The fix to this problem checks that the pfn <-> page linkages are correct by calculating the page for the pfn and then checking that page_to_pfn on that page returns the original pfn. Unfortunately, in SPARSEMEM configurations, this results in reading from the page flags to determine the correct section. Since the memmap here has been freed, junk is read from memory and the check is no longer robust. In the best case, reading from /proc/pagetypeinfo will give you the wrong answer. In the worst case, you get SEGVs, Kernel OOPses and hung CPUs. Furthermore, ioremap implementations that use pfn_valid to disallow the remapping of normal memory will break. This patch allows architectures to provide their own pfn_valid function instead of using the default implementation used by sparsemem. The architecture-specific version is aware of the memmap state and will return false when passed a pfn for a freed page within a valid section.

Choosing TMPFS_XATTR default N was switching off TMPFS_POSIX_ACL, even if it had been Y in oldconfig; and Linus reports that PulseAudio goes subtly wrong unless it can use ACLs on /dev/shm. Make TMPFS_POSIX_ACL select TMPFS_XATTR (and depend upon TMPFS), and move the TMPFS_POSIX_ACL entry before the TMPFS_XATTR entry, to avoid asking unnecessary questions then ignoring their answers.

commit 9ec26907 ("timerfd: Manage cancelable timers in timerfd") introduced a CONFIG_HIGHRES_TIMERS (should be CONFIG_HIGH_RES_TIMERS) typo, which caused applications depending on CLOCK_REALTIME timers to become sluggy due to the fact that the time base of the realtime timers was not updated when the wall clock time was set. This causes anything from 100% CPU use for some applications to odd delays and hickups.

The bonding driver initializes some data structures only after its ndo_open routine is called. Among them is the initalization of the alb tx and rx hash locks. So if we add or remove a slave without first opening the bond master device, we run the risk of trying to lock/unlock a spinlock that has garbage for data in it, which results in our above softlock. Note that sometimes this works, because in many cases an unlocked spinlock has the raw_lock parameter initialized to zero (meaning that the kzalloc of the net_device private data is equivalent to calling spin_lock_init), but thats not true in all cases, and we aren't guaranteed that condition, so we need to pass the relevant spinlocks through the spin_lock_init function. Fix it by moving the spin_lock_init calls for the tx and rx hashtable locks to the ndo_init path, so they are ready for use by the bond_store_slaves path. Change notes: v2) Based on conversation with Jay and Nicolas it seems that the ability to enslave devices while the bond master is down should be safe to do. As such this is an outlier bug, and so instead we'll just initalize the errant spinlocks in the init path rather than the open path, solving the problem. We'll also remove the warnings about the bond being down during enslave operations, since it should be safe v3) Fix spelling error Signed-off-by: NNeil Horman <nhorman@tuxdriver.com> Reported-by: jtluka@redhat.com CC: Jay Vosburgh <fubar@us.ibm.com> CC: Andy Gospodarek <andy@greyhouse.net> CC: nicolas.2p.debian@gmail.com CC: "David S.

On ARM, memory accesses through packed pointers behave in unexpected ways in GCC releases 4.3 and higher; see https://lkml.org/lkml/2011/2/2/163 for discussion. In this particular case, 32-bit I/O registers are accessed bytewise, causing incorrect setting of the DMA address registers which in turn leads to an error interrupt storm that brings the system to a halt. Since the mac_regs structure does not need any packing anyway, this patch simply removes the attribute to fix the issue. Signed-off-by: NUlrich Hecht <uli@suse.de> Signed-off-by: NDavid S.

If an ASCONF chunk is outstanding, then the following ASCONF chunk will be queued for later transmission. But when we free the asoc, we forget to free the ASCONF queue at the same time, this will cause memory leak. Signed-off-by: NWei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: NDavid S.

CMD19 -- The offical way to validate bus widths from the JEDEC spec does not work on all platforms. Some platforms that use PCI/PCIe to connect their SD controllers are known to fail. If the quirk MMC_BUS_WIDTH_TEST is not defined we try to figure out the bus width by reading the ext_csd at different bus widths and compare this against the ext_csd read in 1 bit mode. If no ext_csd is available we default to 1 bit operations. Code has been tested on mmp2 against 8 bit eMMC and Transcend 2GB card that is known to not work in 4 bit mode. The physical pins on the card are not present to support 4 bit operation. Signed-off-by: NPhilip Rakity <prakity@marvell.com> Signed-off-by: NChris Ball <cjb@laptop.org>

With this change, you can (and should) build with ARCH=tilepro for the current 32-bit chips. Building with ARCH=tile continues to work, but we've renamed the defconfig file to tilepro_defconfig for consistency. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>
