2017-01-18ARC: Revert "ARC: mm: IOC: Don't enable IOC by default"Vineet Gupta1-1/+1
The programming model has been fixed with prev patches so re-enable it by default This reverts commit 23cb1f644019bac49d87b4dd7c1eac0569cc4f53. Signed-off-by: Vineet Gupta <[email protected]>
2017-01-18ARC: mm: split arc_cache_init to allow __init reaping of bulkVineet Gupta1-14/+19
arc_cache_init() is called for each core so can't be tagged __init. However bulk of it is only executed by master core and thus is candidate for __init reaping. So split it up to allow that. Signed-off-by: Vineet Gupta <[email protected]>

2017-01-18ARCv2: IOC: Adhere to progamming model guidelines to avoid DMA corruptionVineet Gupta2-3/+50
On AXS103 release bitfiles, DMA data corruptions were seen because IOC setup was not following the recommended way in documentation. Flipping IOC on when caches are enabled or coherency transactions are in flight, might cause some of the memory operations to not observe coherency as expected. So strictly follow the programming model recommendations as documented in comment header above arc_ioc_setup() Signed-off-by: Vineet Gupta <[email protected]>

The extension is necessary right now because we need a proper way to unbreak LTTNG, which iscurrently non functional due to the removal of the notifiers. Surely it's out of tree, but it's widely used by distros. The simple solution would have been to reserve a state for LTTNG, but I'm not fond about unused crap in the kernel and the dynamic range, which we admittedly should have done right away, allows us to remove quite some of the hardcoded states, i.e. those which have no ordering requirements.

2017-01-18ovl: fix possible use after free on redirect dir lookupAmir Goldstein1-9/+18
ovl_lookup_layer() iterates on path elements of d->name.name but also frees and allocates a new pointer for d->name.name. For the case of lookup in upper layer, the initial d->name.name pointer is stable (dentry->d_name), but for lower layers, the initial d->name.name can be d->redirect, which can be freed during iteration. [SzM] Keep the count of remaining characters in the redirect path and calculate the current position from that. This works becuase only the prefix is modified, the ending always stays the same.

The current hardware is not able to run with all cores enabled at a cluster frequency superior at 1536MHz. But the currently shipped u-boot for the platform still reports an OPP table with possible DVFS frequency up to 2GHz, and will not change since the off-tree linux tree supports limiting the OPPs with a kernel parameter. A recent u-boot change reports the boot-time DVFS around 100MHz and the default performance cpufreq governor sets the maximum frequency. Previous version of u-boot reported to be already at the max OPP and left the OPP as is. Nevertheless, other governors like ondemand could setup the max frequency and make the system crash. This patch disables the DVFS clock and disables cpufreq.

But if we are at the maximum ID and then ask for the "next" one, we may wrap back to zero. In this case, userspace may loop forever, because it will start querying again at zero. We'll fix this in userspace as well, but for the kernel, return -ENOENT if we ask for the next quota ID past UINT_MAX so the caller knows to stop.

2017-01-17xfs: replace xfs_mode_to_ftype table with switch statementAmir Goldstein3-18/+25
The size of the xfs_mode_to_ftype[] conversion table was too small to handle an invalid value of mode=S_IFMT. Instead of fixing the table size, replace the conversion table with a conversion helper that uses a switch statement. Suggested-by: Christoph Hellwig <[email protected]> Reviewed-by: Darrick J.

2017-01-17xfs: add missing include dependencies to xfs_dir2.hAmir Goldstein1-0/+3
xfs_dir2.h dereferences some data types in inline functions and fails to include those type definitions, e.g.: xfs_dir2_data_aoff_t, struct xfs_da_geometry.

2017-01-17xfs: sanity check directory inode di_sizeAmir Goldstein2-3/+7
This changes fixes an assertion hit when fuzzing on-disk i_mode values. The easy case to fix is when changing an empty file i_mode to S_IFDIR. In this case, xfs_dinode_verify() detects an illegal zero size for directory and fails to load the inode structure from disk. For the case of non empty file whose i_mode is changed to S_IFDIR, the ASSERT() statement in xfs_dir2_isblock() is replaced with return -EFSCORRUPTED, to avoid interacting with corrupted jusk also when XFS_DEBUG is disabled.

2017-01-17xfs: make the ASSERT() condition likelyAmir Goldstein1-3/+3
The ASSERT() condition is the normal case, not the exception, so testing the condition should be likely(), not unlikely().

2017-01-17scsi: mpt3sas: fix hang on ata passthrough commandsJames Bottomley2-14/+38
mpt3sas has a firmware failure where it can only handle one pass through ATA command at a time. If another comes in, contrary to the SAT standard, it will hang until the first one completes (causing long commands like secure erase to timeout). The original fix was to block the device when an ATA command came in, but this caused a regression with commit 669f044170d8933c3d66d231b69ea97cb8447338 Author: Bart Van Assche <[email protected]> Date: Tue Nov 22 16:17:13 2016 -0800 scsi: srp_transport: Move queuecommand() wait code to SCSI core So fix the original fix of the secure erase timeout by properly returning SAM_STAT_BUSY like the SAT recommends. The original patch also had a concurrency problem since scsih_qcmd is lockless at that point (this is fixed by using atomic bitops to set and test the flag).

2017-01-17qla2xxx: Disable out-of-order processing by default in firmwareQuinn Tran1-6/+0
Out of order(OOO) processing requires initiator, switch and target to support OOO. In today's environment, none of the switches support OOO. OOO requires extra buffer space which affect performance. By turning ON this feature in QLogic's FW, it delays error recovery because dropped frame is treated as out of order frame. We're turning OFF this option of speed up error recovery.
