identify_ramdisk_image() returns 0 (not -1) if a gzipped ramdisk is found:
if (buf[0] == 037 && ((buf[1] == 0213) || (buf[1] == 0236))) {
printk(KERN_NOTICE
"RAMDISK: Compressed image found at block %d\n",
start_block);
nblocks = 0;
^^^^^^^^^^^
goto done;
}...
done:
sys_lseek(fd, start_block * BLOCK_SIZE, 0);
kfree(buf);
return nblocks;
^^^^^^^^^^^^^^Hence correct the typo in the comment, which has existed since the
addition of compressed ramdisk support in 1.3.48.Signed-off-by: Geert Uytterhoeven

The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) /

We currently use a PM notifier to disable user mode helpers before suspend
and hibernation and to re-enable them during resume. However, this is not
an ideal solution, because if any drivers want to upload firmware into
memory before suspend, they have to use a PM notifier for this purpose and
there is no guarantee that the ordering of PM notifiers will be as
expected (ie. the notifier that disables user mode helpers has to be run
after the driver's notifier used for uploading the firmware).For this reason, it seems better to move the disabling and enabling of
user mode helpers to separate functions that will be called by the PM core
as necessary.[akpm@linux-foundation.org: remove unneeded ifdefs]

There are off-by-one errors in decompress_exec() when calculating the length of
optional "original file name" and "comment" fields: the "ret" index is not
incremented when terminating '\0' character is reached. The check of the buffer
overflow (after an "extra-field" length was taken into account) is also fixed.I've encountered this off-by-one error when tried to reuse
gzip-header-parsing part of the decompress_exec() function. There was an
"original file name" field in the payload (with miscalculated length) and
zlib_inflate() returned Z_DATA_ERROR. But after the fix similar to this
one all worked fine.Signed-off-by: Volodymyr G Lukiianyk

The page fault path for normal pages, if the fault is neither a no-page
fault nor a write-protect fault, will update the DIRTY and ACCESSED bits
in the page table appropriately.The hugepage fault path, however, does not do this, handling only no-page
or write-protect type faults. It assumes that either the ACCESSED and
DIRTY bits are irrelevant for hugepages (usually true, since they are
never swapped) or that they are handled by the arch code.This is inconvenient for some software-loaded TLB architectures, where the
_PAGE_ACCESSED (_PAGE_DIRTY) bits need to be set to enable read (write)
access to the page at the TLB miss. This could be worked around in the
arch TLB miss code, but the TLB miss fast path can be made simple more
easily if the hugetlb_fault() path handles this, as the normal page fault
path does.Signed-off-by: David Gibson

A series of patches introduce a generic header file for the software
IO/TLB implementation in lib/swiotlb.c. Currently each architecture using
this code defines the prototypes itself. The prototypes are moved to
include/linux/swiotlb.h and this file is included in architecture specific
code for X86 and IA64.This patch:
Create include/linux/swiotlb.h file which contains all function prototypes
for the lib/swiotlb.c file.(akpm: the dependent patches will be trickled through arch trees)

When we skip unrecognized options in xfs_fs_remount we should just break
out of the switch and not return because otherwise we may skip clearing
the xfs-internal read-only flag. This will only show up on some
operations like touch because most read-only checks are done by the VFS
which thinks this filesystem is r/w. Eventually we should replace the
XFS read-only flag with a helper that always checks the VFS flag to make
sure they can never get out of sync.Bug reported and fix verified by Marcel Beister on #xfs.
