Pull ARM fixes from Russell King: "A few more ARM fixes: - the assembly backtrace code suffers problems with the new printk() implementation which assumes that kernel messages without KERN_CONT should have newlines inserted between them. Fix this. - fix a section naming error - ".init.text" rather than ".text.init" - preallocate DMA debug memory at core_initcall() time rather than fs_initcall(), as we have some core drivers that need to use DMA mapping - and that triggers a kernel warning from the DMA debug code. - fix XIP kernels after the ro_after_init changes made this data permanently read-only" * 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: Fix XIP kernels ARM: 8628/1: dma-mapping: preallocate DMA-debug hash tables in core_initcall ARM: 8624/1: proc-v7m.S: fix init section name ARM: fix backtrace

ext4: sanity check the block and cluster size at mount time

2016-11-20T01:58:15Z

If the block size or cluster size is insane, reject the mount. This is important for security reasons (although we shouldn't be just depending on this check).

fscrypto: don't use on-stack buffer for key derivation

2016-11-20T01:56:13Z

With the new (in 4.9) option to use a virtually-mapped stack (CONFIG_VMAP_STACK), stack buffers cannot be used as input/output for the scatterlist crypto API because they may not be directly mappable to struct page. get_crypt_info() was using a stack buffer to hold the output from the encryption operation used to derive the per-file key. Fix it by using a heap buffer. This bug could most easily be observed in a CONFIG_DEBUG_SG kernel because this allowed the BUG in sg_set_buf() to be triggered.

fscrypto: don't use on-stack buffer for filename encryption

2016-11-20T01:56:06Z

With the new (in 4.9) option to use a virtually-mapped stack (CONFIG_VMAP_STACK), stack buffers cannot be used as input/output for the scatterlist crypto API because they may not be directly mappable to struct page. For short filenames, fname_encrypt() was encrypting a stack buffer holding the padded filename. Fix it by encrypting the filename in-place in the output buffer, thereby making the temporary buffer unnecessary. This bug could most easily be observed in a CONFIG_DEBUG_SG kernel because this allowed the BUG in sg_set_buf() to be triggered.

i2c: i2c-mux-pca954x: fix deselect enabling for device-tree

2016-11-19T20:49:29Z

Deselect functionality can be ignored for device-trees with "i2c-mux-idle-disconnect" entries if no platform_data is available. By enabling the deselect functionality outside the platform_data block the logic works as it did in previous kernels.
