* | Blackfin: fix data cache flushing when doing icache flushingMike Frysinger2009-06-123-36/+16
| | | | | | | | | | | | | | | | | | | | | | Make sure we flush all data caches and their write buffers before flushing icache, otherwise random edge cases could crop up where stale data is read into icache from external memory. As fallout, punt the combined icache + dcache flush function since we cannot safely do them back to back -- the SSYNC is needed between the dcache flush and the icache flush.

* flat: fix data sections alignmentOskar Schirmer2009-05-291-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flat loader uses an architecture's flat_stack_align() to align the stack but assumes word-alignment is enough for the data sections. However, on the Xtensa S6000 we have registers up to 128bit width which can be used from userspace and therefor need userspace stack and data-section alignment of at least this size. This patch drops flat_stack_align() and uses the same alignment that is required for slab caches, ARCH_SLAB_MINALIGN, or wordsize if it's not defined by the architecture. It also fixes m32r which was obviously kaput, aligning an uninitialized stack entry instead of the stack pointer.

* Blackfin SPI Driver: Make mmc_spi driver work on BlackfinWolfgang Muees2009-04-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | 1. Rewrite of the non-dma data transfer functions to use only ONE mode of TIMOD (TIMOD=0x1). With TIMOD=0, it was not possible to set the TX bit pattern. So the TDBR = 0xFFFF inside the read calls won't work. 2. Clear SPI_RDBR before reading and before duplex transfer. Otherwise the garbage data in RDBR will get read. Since mmc_spi uses a lot of duplex transfers, this is the main cause of mmc_spi failure. 3. Poll RXS for transfer completion. Polling SPIF or TXS cannot guarantee transfer completion. This may interrupt a transfer before it is finished. Also this may leave garbage data in buffer and affect next transfer.

To make use of this feature, set chip_select = 0 and add a proper cs_gpio to your controller_data. struct spi_board_info .chip_select = 0 struct bfin5xx_spi_chip .cs_gpio = GPIO_P### There are various SPI devices that require SPI MODE_0, and need to have the Chip Selects asserted during the entire transfer.

Because now <asm/ftrace.h> is included unconditionally in <linux/ftrace.h> all archs that don't already had this include get an empty one for free.

Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>
