2014-03-02ARM: dts: am43xx: add support for parallel NAND flashPekon Gupta
This patch: - enables GPMC h/w and ELM h/w engine for AM43xx devices (am4372.dtsi) - adds pinmux and DT node for Micron 4K-paged x8 NAND device (MT29F4G08AB) present on following boards: am43x-epos-evm: On this board, NAND Flash control lines are muxed with QSPI, Thus only one of the two can be used at a time. Selection is controlled by: (a) dynamically driving following GPIO pin from software GPMC_A0(GPIO) == 0 NAND is selected (default) GPMC_A0(GPIO) == 1 eMMC is selected Signed-off-by: Pekon Gupta <pekon@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

Since we will probably never implement full HP-UX support, we prefer to drop this compatibility to make it easier for us with Linux userspace programs which mostly never checked for both values.

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.

2014-02-02hpfs: remember free spaceMikulas Patocka
Previously, hpfs scanned all bitmaps each time the user asked for free space using statfs. This patch changes it so that hpfs scans the bitmaps only once, remembes the free space and on next invocation of statfs it returns the value instantly. New versions of wine are hammering on the statfs syscall very heavily, making some games unplayable when they're stored on hpfs, with load times in minutes. This should be backported to the stable kernels because it fixes user-visible problem (excessive level load times in wine).
