* ext4: export iov_shorten from kernel for ext4's useEric Sandeen2008-01-281-0/+1

* ext4: Support large filesAneesh Kumar K.V2008-01-283-11/+33
| | | | | | | | | | | | | | | This patch converts ext4_inode i_blocks to represent total blocks occupied by the inode in file system block size. Earlier the variable used to represent this in 512 byte block size. This actually limited the total size of the file. The feature is enabled transparently when we write an inode whose i_blocks cannot be represnted as 512 byte units in a 48 bit variable. inode flag EXT4_HUGE_FILE_FL Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
* ext4: Add support for 48 bit inode i_blocks.Aneesh Kumar K.V2008-01-283-11/+119
| | | | | | | | | | | | | | | Use the __le16 l_i_reserved1 field of the linux2 struct of ext4_inode to represet the higher 16 bits for i_blocks. With this change max_file size becomes (2**48 -1 )* 512 bytes. We add a RO_COMPAT feature to the super block to indicate that inode have i_blocks represented as a split 48 bits. Super block with this feature set cannot be mounted read write on a kernel with CONFIG_LSF disabled.

* ext4: add ext4_group_t, and change all group variables to this type.Avantika Mathur2008-01-289-87/+91
| | | | | | | | | | | | | In many places variables for block group are of type int, which limits the maximum number of block groups to 2^31. Each block group can have up to 2^15 blocks, with a 4K block size, and the max filesystem size is limited to 2^31 * (2^15 * 2^12) = 2^58 -- or 256 PB This patch introduces a new type ext4_group_t, of type unsigned long, to represent block group numbers in ext4. All occurrences of block group variables are converted to type ext4_group_t. Signed-off-by: Avantika Mathur <mathur@us.ibm.com>

* ext4: Introduce ext4_lblk_tAneesh Kumar K.V2008-01-288-226/+143
| | | | | | | | | | | | | | | | | | | This patch adds a new data type ext4_lblk_t to represent the logical file blocks. This is the preparatory patch to support large files in ext4 The follow up patch with convert the ext4_inode i_blocks to represent the number of blocks in file system block size. This changes makes it possible to have a block number 2**32 -1 which will result in overflow if the block number is represented by signed long.

* ext4: Avoid rec_len overflow with 64KB block sizeJan Kara2008-01-283-46/+63
| | | | | | | | | | With 64KB blocksize, a directory entry can have size 64KB which does not fit into 16 bits we have for entry lenght. So we store 0xffff instead and convert value when read from / written to disk. The patch also converts some places to use ext4_next_entry() when we are changing them anyway.

* ext4: Support large blocksize up to PAGESIZETakashi Sato2008-01-282-2/+7
| | | | | | | | | | | | | | | | | | | | | | | This patch set supports large block size(>4k, <=64k) in ext4, just enlarging the block size limit. But it is NOT possible to have 64kB blocksize on ext4 without some changes to the directory handling code. The reason is that an empty 64kB directory block would have a rec_len == (__u16)2^16 == 0, and this would cause an error to be hit in the filesystem. The proposed solution is treat 64k rec_len with a an impossible value like rec_len = 0xffff to handle this. The Patch-set consists of the following 2 patches. [1/2] ext4: enlarge blocksize - Allow blocksize up to pagesize [2/2] ext4: fix rec_len overflow - prevent rec_len from overflow with 64KB blocksize Now on 64k page ppc64 box runs with this patch set we could create a 64k block size ext4dev, and able to handle empty directory block.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The audit of _p usage shows various drivers assume inb_p is somehow atomic. Of course it isn't and the delay can be split from the I/O cycle causing a timing violation on chips that matter (eg this one) With the proposed use of udelay() for some _p delays this will cease to be a mostly theoretical bug (as the delay stall is unsplittable) and wants fixing.

| * | sh: add spi header and r2d platform data V3Magnus Damm2008-01-282-0/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the header file asm/spi.h and board specific code for the r2d board. The header file contains a structure that should be used to point out a single spi bus. The board specific code for r2d is updated with such a structure for the new spi_sh_sci driver. The structure contains a chip select callback plus information about the R9701 rtc chip which is attached to the spi bus.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the board specific irq code for r7780rp. The new code is very similar to the other highlander implementations, with the exception that the r7780rp handles pci interrupts using IRL. To simplify the pci code and use the same interrupt numbers as r7780mp and r7785rp we hook in to the cpu specific pci vectors. The pci interrupts and the push switch all work well with and without this patch. CF and AX88796 are not ok though and the source of the problem is unknown at this point. The AX88796 does for not detect it's proper mac address (IPL gets it right) and the kernel hangs on CF access. As a workaround this patch removes the CF and the AX88796 from the platform datain case of r7780rp. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This driver implements Sega's Packet Interface (SPI) - at least partially. It will also read disks in SEGA's propreitary GD format. Unlike previous drivers (which were never in mainline) this uses DMA and not PIO to read disks. It is a new driver, not a refactoring of old drivers.
