2014-02-18ARM: shmobile: Remove Koelsch DT reference legacy clock bitsMagnus Damm
Koelsch DT reference is these days built for multiplatform only which means that CCF comes with the package. Remove unused legacy code ifdefs to clean up the code.

2014-02-18ARM: shmobile: Remove KZM9D board codeMagnus Damm
Get rid of KZM9D board code written in C. This version of the C board code was used in the case of multiplatform, but these days DT can be used instead, so because of that simply get rid of the C code to simplify and save space.

Ether MAC is a DMA-capable device and so should have 'dev.dma_mask' and 'dev.coherent_dma_mask' fields set properly, to reflect 32-bit DMA addressing ability. Currently, the code works without DMA masks but as we would have to enable CONFIG_HIGHMEM to access the full board memory in the future, when support for NETIF_F_SG would be added to the 'sh_eth' driver as well, the correct DMA masks should start to matter...

Remove ifdefs to make the Lager USBHS device always present. This makes it more like other devices, no need to be special.

2014-02-02hpfs: optimize quad buffer loadingMikulas Patocka
HPFS needs to load 4 consecutive 512-byte sectors when accessing the directory nodes or bitmaps. We can't switch to 2048-byte block size because files are allocated in the units of 512-byte sectors. Previously, the driver would allocate a 2048-byte area using kmalloc, copy the data from four buffers to this area and eventually copy them back if they were modified. In the current implementation of the buffer cache, buffers are allocated in the pagecache. That means that 4 consecutive 512-byte buffers are stored in consecutive areas in the kernel address space. So, we don't need to allocate extra memory and copy the content of the buffers there. This patch optimizes the code to avoid copying the buffers. It checks if the four buffers are stored in contiguous memory - if they are not, it falls back to allocating a 2048-byte area and copying data there.
