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: David Howells <dhowells@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

In commit c441d4a5 ("MIPS: mm: Only build one microassembler that is suitable"), the Makefile at arch/mips/mm was rewritten to only build the "right" microassembler file, depending on whether CONFIG_CPU_MICROMIPS is set or not. In the files, however, there are still preprocessor definitions depending on CONFIG_CPU_MICROMIPS. The #ifdef around them can now never evaluate to true, so let's remove them altogether. This inconsistency was found using the undertaker-checkpatch tool. Signed-off-by: Andreas Ruprecht <rupran@einserver.de> Reviewed-by: Maciej W.

The current code uses bits 0-6 of the sys_cpupll register to calculate core clock speed. However this is only valid on Au1300, on all earlier models the hardware only uses bits 0-5 to generate core clock. This fixes clock calculation on the MTX1 (Au1500), where bit 6 of cpupll is set as well, which ultimately lead the code to calculate a bogus cpu core clock and also uart base clock down the line.

There doesn't seem to be any valid reason to allocate the pages array with the same flags as the buffer itself. Doing so can eventually lead to the following safeguard in mm/slab.c's cache_grow() to be hit: if (unlikely(flags & GFP_SLAB_BUG_MASK)) { pr_emerg("gfp: %un", flags & GFP_SLAB_BUG_MASK); BUG(); } This happens when buffers are allocated with __GFP_DMA32 or __GFP_HIGHMEM. Fix this by allocating the pages array with GFP_KERNEL to follow what is done elsewhere in this file. Using GFP_KERNEL in __iommu_alloc_buffer() is safe because atomic allocations are handled by __iommu_alloc_atomic().
