This commit adds the Device Tree files for the Armada 39x family of processors, as well as one Armada 398 Development Board. Like for other Marvell EBU families, a common armada-39x.dtsi contains the description of the common features of all Armada 39x SoCs, while armada-390.dtsi and armada-398.dtsi respectively describe the specificities of those SoCs. Finally, an armada-398-db.dts file is added to describe the Armada 398 Development Board itself. So far, the following features are supported: * SMP: dual Cortex-A9 * Basic ARM IPs: SCU, timer, GIC, L2 cache * Basic Marvell IPs: pin-muxing, clocks, system controller, MBus controller, MPIC interrupt controller, timer, CPU reset for SMP, PMSU. * I2C * SPI * SDHCI * XOR * NAND * UART * PCIe Additional features will be supported in the future.

The Device Tree nodes describing the MPIC nodes on Armada 370, 375, 38x and XP had a unit address that did not match the first reg property, as suggested by the ePAPR. This commit fixes that.

This commit adds the stdout-path property in /chosen for all Armada boards that were not yet carrying this property, and gets rid of /chosen/bootargs which becomes unneeded: earlyprintk should not be used by default, and the console= parameter is replaced by the /chosen/stdout-path property.

This commit adds 'serialX' aliases for the various serial ports on Armada 370, 375, 38x and XP platforms. It will allow the usage of the stdout-path property. Signed-off-by:

Thomas Petazzoni authored
Having aliases for Ethernet devices is useless, since the networking subsystem unfortunately doesn't care about aliases to name network interfaces. Note that the 'aliases' nodes in armada-370-xp.dtsi and armada-xp.dtsi become empty, but that we keep it as is since a followup patch will re-add some aliases to it. Signed-off-by:

On Marvell Armada 38x, the USB2 controller registers are at 0x58000, so the corresponding Device Tree node should have a unit address of 58000, and not 50000. We were using 50000 due to an incorrect copy/pastebin of Armada 370/XP code. Signed-off-by:

.. after extensive statistical analysis of my G+ polling, I've come to the inescapable conclusion that internet polls are bad. Big surprise. But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38% margin, in a poll that people weren't even supposed to participate in. Who can argue with solid numbers like that? 5,796 votes from people who can't even follow the most basic directions? In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%, but with a total of 29,110 votes right now. Now, arguably, that vote spread is only about 3,200 votes, which is less than the almost six thousand votes that the "please ignore" poll got, so it could be considered noise. But hey, I asked, so I'll honor the votes.

As it is, we have debugfs_remove() racing with symlink traversals. Supply ->evict_inode() and do freeing there - inode will remain pinned until we are done with the symlink body. And rip the idiocy with checking if dentry is positive right after we'd verified debugfs_positive(), which is a stronger check... Cc: stable@vger.kernel.org Signed-off-by: -

I've noticed significant locking contention in memory reclaimer around sb_lock inside grab_super_passive(). Grab_super_passive() is called from two places: in icache/dcache shrinkers (function super_cache_scan) and from writeback (function __writeback_inodes_wb). Both are required for progress in memory allocator. Grab_super_passive() acquires sb_lock to increment sb->s_count and check sb->s_instances. It seems sb->s_umount locked for read is enough here: super-block deactivation always runs under sb->s_umount locked for write. Protecting super-block itself isn't a problem: in super_cache_scan() sb is protected by shrinker_rwsem: it cannot be freed if its slab shrinkers are still active. Inside writeback super-block comes from inode from bdi writeback list under wb->list_lock. This patch removes locking sb_lock and checks s_instances under s_umount: generic_shutdown_super() unlinks it under sb->s_umount locked for write. New variant is called trylock_super() and since it only locks semaphore, callers must call up_read(&sb->s_umount) instead of drop_super(sb) when they're done. Signed-off-by:

Fix up the following scripted S_ISDIR/S_ISREG/S_ISLNK conversions (or lack thereof) in cachefiles: (1) Cachefiles mostly wants to use d_can_lookup() rather than d_is_dir() as it doesn't want to deal with automounts in its cache. (2) Coccinelle didn't find S_IS* expressions in ASSERT() statements in cachefiles. Signed-off-by: -

Convert the following where appropriate: (1) S_ISLNK(dentry->d_inode) to d_is_symlink(dentry). (2) S_ISREG(dentry->d_inode) to d_is_reg(dentry). (3) S_ISDIR(dentry->d_inode) to d_is_dir(dentry). This is actually more complicated than it appears as some calls should be converted to d_can_lookup() instead. The difference is whether the directory in question is a real dir with a ->lookup op or whether it's a fake dir with a ->d_automount op. In some circumstances, we can subsume checks for dentry->d_inode not being NULL into this, provided we the code isn't in a filesystem that expects d_inode to be NULL if the dirent really *is* negative (ie. if we're going to use d_inode() rather than d_backing_inode() to get the inode pointer). Note that the dentry type field may be set to something other than DCACHE_MISS_TYPE when d_inode is NULL in the case of unionmount, where the VFS manages the fall-through from a negative dentry to a lower layer. In such a case, the dentry type of the negative union dentry is set to the same as the type of the lower dentry. However, if you know d_inode is not NULL at the call site, then you can use the d_is_xxx() functions even in a filesystem. There is one further complication: a 0,0 chardev dentry may be labelled DCACHE_WHITEOUT_TYPE rather than DCACHE_SPECIAL_TYPE. Strictly, this was intended for special directory entry types that don't have attached inodes. The following perl+coccinelle script was used: use strict; my @callers; open($fd, 'git grep -l \'S_IS[A-Z].*->d_inode\' |') || die "Can't grep for S_ISDIR and co. callers"; @callers = <$fd>; close($fd); unless (@callers) { print "No matches\n"; exit(0); } my @cocci = ( '@@', 'expression E;', '@@', '', '- S_ISLNK(E->d_inode->i_mode)', '+ d_is_symlink(E)', '', '@@', 'expression E;', '@@', '', '- S_ISDIR(E->d_inode->i_mode)', '+ d_is_dir(E)', '', '@@', 'expression E;', '@@', '', '- S_ISREG(E->d_inode->i_mode)', '+ d_is_reg(E)' ); my $coccifile = "tmp.sp.cocci"; open($fd, ">$coccifile") || die $coccifile; print($fd "$_\n") || die $coccifile foreach (@cocci); close($fd); foreach my $file (@callers) { chomp $file; print "Processing ", $file, "\n"; system("spatch", "--sp-file", $coccifile, $file, "--in-place", "--no-show-diff") == 0 || die "spatch failed"; } [AV: overlayfs parts skipped] Signed-off-by: -
