* leds: convert IDE trigger to common disk triggerStephan Linz2016-06-207-17/+26
| | | | | | | | | | | | | | | | | | | | | | This patch converts the IDE specific LED trigger to a generic disk activity LED trigger. The libata core is now a trigger source just like before the IDE disk driver. It's merely a replacement of the string ide by disk. The patch is taken from http://dev.gentoo.org/~josejx/ata.patch and is widely used by any ibook/powerbook owners with great satisfaction. Likewise, it is very often used successfully on different ARM platforms. Unlike the original patch, the existing 'ide-disk' trigger is still available for backward compatibility. That reduce the amount of patches in affected device trees out of the mainline kernel. For further development, the new name 'disk-activity' should be used.

| * reiserfs: check kstrdup failureMikulas Patocka2016-05-251-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Check out-of-memory failure of the kstrdup option. Note that the argument "arg" may be NULL (in that case kstrup returns NULL), so out of memory condition happened if arg was non-NULL and kstrdup returned NULL. The patch also changes the call to replace_mount_options - if we didn't pass any filesystem-specific options, we don't call replace_mount_options (thus we don't erase existing reported options). Note that to properly report options after remount, the reiserfs filesystem should implement the show_options method. Without the show_options method, options changed with remount replace existing options. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Jan Kara <jack@suse.cz>
| * udf: Use correct partition reference number for metadataAlden Tondettar2016-05-193-12/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UDF/OSTA terminology is confusing. Partition Numbers (PNs) are arbitrary 16-bit values, one for each physical partition in the volume. Partition Reference Numbers (PRNs) are indices into the the Partition Map Table and do not necessarily equal the PN of the mapped partition. The current metadata code mistakenly uses the PN instead of the PRN when mapping metadata blocks to physical/sparable blocks. Windows-created UDF 2.5 discs for some reason use large, arbitrary PNs, resulting in mount failure and KASAN read warnings in udf_read_inode(). For example, a NetBSD UDF 2.5 partition might look like this: PRN PN Type --- -- ---- 0 0 Sparable 1 0 Metadata Since PRN == PN, we are fine. But Windows could gives us: PRN PN Type --- ---- ---- 0 8192 Sparable 1 8192 Metadata So udf_read_inode() will start out by checking the partition length in sbi->s_partmaps[8192], which is obviously out of bounds. Fix this by creating a new field (s_phys_partition_ref) in struct udf_meta_data, referencing whatever physical or sparable map has the same partition number as the metadata partition.

| * udf: Use IS_ERR when loading metadata mirror file entryAlden Tondettar2016-05-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | Currently when udf_get_pblock_meta25() fails to map a block using the primary metadata file, it will attempt to load the mirror file entry by calling udf_find_metadata_inode_efe(). That function will return a ERR_PTR if it fails, but the return value is only checked against NULL. Test the return value using IS_ERR() and change it to NULL if needed.

| * udf: Don't BUG on missing metadata partition descriptorAlden Tondettar2016-05-191-2/+3
| | | | | | | | | | | | | | | | | | | | Currently, if a metadata partition map is missing its partition descriptor, then udf_get_pblock_meta25() will BUG() out the first time it is called. This is rather drastic for a corrupted filesystem, so just treat this case as an invalid mapping instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upon booting, I occasionally spotted some BUGs triggered by the internal DMA test routine executed upon driver probing. This was detected by SLUB_DEBUG ("Freechain corrupt" or "Redzone overwritten"). Tracking this down located a problem in passing 0 as offset in dma_map_page(). As kmalloc, especially when used with SLUB_DEBUG, may return a non page aligned address. This patch fixes this issue by passing the correct offset in dma_map_page(). Tested on a custom Armada XP board.

When running at 400khz, measurements show that SCL spends 0.8125 uS/1.666 uS high/low which violates the requirement for minimum high period of SCL provided in datasheet Table 7.6 which is 1 uS. Switching to 100khz gives us 5 uS/5 uS high/low which both fall above the minimum given values for 100 khz, 4.0 uS/4.7 uS high/low. Without this patch occasionally a voltage set operation from the kernel will appear to have worked but the actual voltage reflected on the PMIC will not have updated, causing problems especially with cpufreq that may update to a higher OPP without actually raising the voltage on DCDC2, leading to a hang.

When booting with a compressed kernel, we need to be careful how we populate memory close to DDR start. AUTO_ZRELADDR is enabled by default in multi-arch enabled configurations, which place some restrictions on where the kernel is placed and where it will be uncompressed to on boot. AUTO_ZRELADDR takes the decompressor code's start address and masks out the bottom 28 bits to obtain an address to uncompress the kernel to (thus a load address of 0x42000000 means that the kernel will be uncompressed to 0x40000000 i.e. DDR START on this platform). Even changing the load address to after the co-processor's shared memory won't render a booting platform, since the AUTO_ZRELADDR algorithm still ensures the kernel is uncompressed into memory shared with the first co-processor (0x40000000). Another option would be to move loading to 0x4A000000, since this will mean the decompressor will decompress the kernel to 0x48000000. However, this would mean a large chunk (0x44000000 => 0x48000000 (64MB)) of memory would essentially be wasted for no good reason. Until we can work with ST to find a suitable memory location to relocate co-processor shared memory, let's disable the shared memory nodes. This will ensure a working platform in the mean time. NB: The more observant of you will notice that we're leaving the DMU shared memory node enabled; this is because a) it is the only one in active use at the time of this writing and b) it is not affected by the current default behaviour which is causing issues.

This is an optional feature of the SD specification.
