This reverts commit 1bd83245. To quote Olof: This commit broke a whole lot of tegra boards in last night's -next here. In particular, I've been looking at tegra20-seaboard, which now doesn't boot with console any more. Breaking existing systems is bad.

The Parallella board comes with a U-Boot bootloader that loads one of two predefined FPGA bitstreams before booting the kernel. Both define an AXI interface to the on-board Epiphany processor. Enable clocks FCLK0..FCLK3 for the Programmable Logic by default. Otherwise accessing, e.g., the ESYSRESET register freezes the board, as seen with the Epiphany SDK tools e-reset and e-hw-rev, using /dev/mem.

Pull xfs fixes from Dave Chinner: "This update fixes a warning in the new pagecache_isize_extended() and updates some related comments, another fix for zero-range misbehaviour, and an unforntuately large set of fixes for regressions in the bulkstat code. The bulkstat fixes are large but necessary. I wouldn't normally push such a rework for a -rcX update, but right now xfsdump can silently create incomplete dumps on 3.17 and it's possible that even xfsrestore won't notice that the dumps were incomplete. Hence we need to get this update into 3.17-stable kernels ASAP. In more detail, the refactoring work I committed in 3.17 has exposed a major hole in our QA coverage. With both xfsdump (the major user of bulkstat) and xfsrestore silently ignoring missing files in the dump/restore process, incomplete dumps were going unnoticed if they were being triggered. Many of the dump/restore filesets were so small that they didn't evenhave a chance of triggering the loop iteration bugs we introduced in 3.17, so we didn't exercise the code sufficiently, either. We have already taken steps to improve QA coverage in xfstests to avoid this happening again, and I've done a lot of manual verification of dump/restore on very large data sets (tens of millions of inodes) of the past week to verify this patch set results in bulkstat behaving the same way as it does on 3.16. Unfortunately, the fixes are not exactly simple - in tracking down the problem historic API warts were discovered (e.g xfsdump has been working around a 20 year old bug in the bulkstat API for the past 10 years) and so that complicated the process of diagnosing and fixing the problems. i.e. we had to fix bugs in the code as well as discover and re-introduce the userspace visible API bugs that we unwittingly "fixed" in 3.17 that xfsdump relied on to work correctly. Summary: - incorrect warnings about i_mutex locking in pagecache_isize_extended() and updates comments to match expected locking - another zero-range bug fix for stray file size updates - a bunch of fixes for regression in the bulkstat code introduced in 3.17" * tag 'xfs-for-linus-3.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: xfs: track bulkstat progress by agino xfs: bulkstat error handling is broken xfs: bulkstat main loop logic is a mess xfs: bulkstat chunk-formatter has issues xfs: bulkstat chunk formatting cursor is broken xfs: bulkstat btree walk doesn't terminate mm: Fix comment before truncate_setsize() xfs: rework zero range to prevent invalid i_size updates mm: Remove false WARN_ON from pagecache_isize_extended() xfs: Check error during inode btree iteration in xfs_bulkstat() xfs: bulkstat doesn't release AGI buffer on error

It's desirable for allnconfig and tinyconfig targets to result in the least amount of code possible. DISABLE_DEV_COREDUMP exists as a way to switch off DEV_COREDUMP regardless if any drivers select WANT_DEV_COREDUMP. This patch renames the option to ENABLE_DEV_COREDUMP and setting it to 'n' (as in allnconfig or tinyconfig) will effectively disable device coredump.

There is a race condition when removing glue directory. It can be reproduced in following test: path 1: Add first child device device_add() get_device_parent() /*find parent from glue_dirs.list*/ list_for_each_entry(k, &dev->class->p->glue_dirs.list, entry) if (k->parent == parent_kobj) { kobj = kobject_get(k); break; } .... class_dir_create_and_add() path2: Remove last child device under glue dir device_del() cleanup_device_parent() cleanup_glue_dir() kobject_put(glue_dir); If path2 has been called cleanup_glue_dir(), but not call kobject_put(glue_dir), the glue dir is still in parent's kset list. Meanwhile, path1 find the glue dir from the glue_dirs.list. Path2 may release glue dir before path1 call kobject_get(). So kernel will report the warning and bug_on. This is a "classic" problem we have of a kref in a list that can be found while the last instance could be removed at the same time. This patch reuse gdp_mutex to fix this race condition.

Starting with version 2.24.51.20140728 MIPS binutils complain loudly about mixing soft-float and hard-float object files, leading to this build failure since GCC is invoked with "-msoft-float" on MIPS: {standard input}: Warning: .gnu_attribute 4,3 requires `softfloat' LD arch/mips/alchemy/common/built-in.o mipsel-softfloat-linux-gnu-ld: Warning: arch/mips/alchemy/common/built-in.o uses -msoft-float (set by arch/mips/alchemy/common/prom.o), arch/mips/alchemy/common/sleeper.o uses -mhard-float To fix this, we detect if GAS is new enough to support "-msoft-float" command option, and if it does, we can let GCC pass it to GAS; but then we also need to sprinkle the files which make use of floating point registers with the necessary ".set hardfloat" directives.

This commit adds the Digi Classic board implementation to the staging/jsm driver. The code here is taken from the staging/dgnc driver and modified to match the serial/jsm state. This work is mostly based on the changes that has been done to the code handling the Digi Neo cards with the inspiration coming from the diff between staging/dgnc and serial/jsm as well as the LKML history for the jsm_neo.c The code compiles now and has no sparse and checkpatch errors or warnings.
