Commit 14f7dd63 ("Copy XFS readdir hack into nfsd code") introduced a bug to generic code which had been extant for a long time in the XFS version -- it started to call through into lookup_one_len() and hence into the file systems' ->lookup() methods without i_mutex held on the directory. This patch fixes it by locking the directory's i_mutex again before calling the filldir functions. The original deadlocks which commit 14f7dd63 was designed to avoid are still avoided, because they were due to fs-internal locking, not i_mutex. While we're at it, fix the return type of nfsd_buffered_readdir() which should be a __be32 not an int -- it's an NFS errno, not a Linux errno. And return nfserrno(-ENOMEM) when allocation fails, not just -ENOMEM. Sparse would have caught that, if it wasn't so busy bitching about __cold__. Commit 05f4f678 ("nfsd4: don't do lookup within readdir in recovery code") introduced a similar problem with calling lookup_one_len() without i_mutex, which this patch also addresses. To fix that, it was necessary to fix the called functions so that they expect i_mutex to be held; that part was done by J. Bruce Fields.

In current code we register/unregister connector object by drm_sysfs_connector_add/remove function. However under some cases, we need to dynamically register or unregister device multiple times, so we have to go through register -> unregister ->register routine. Because after device_unregister function our memory is dirty, we need to do clean operation in order to re-register the device, otherwise the system will crash.

Commit 900af0d9 (PM: Change suspend code ordering) changed the ordering of suspend code in such a way that the platform .prepare() callback is now executed after the device drivers' late suspend callbacks have run. Unfortunately, this turns out to break ARM platforms that need to talk via I2C to power control devices during the .prepare() callback. For this reason introduce two new platform suspend callbacks, .prepare_late() and .wake(), that will be called just prior to disabling non-boot CPUs and right after bringing them back on line, respectively, and use them instead of .prepare() and .finish() for ACPI suspend. Make the PM core execute the .prepare() and .finish() platform suspend callbacks where they were executed previously (that is, right after calling the regular suspend methods provided by device drivers and right before executing their regular resume methods, respectively). It is not necessary to make analogous changes to the hibernation code and data structures at the moment, because they are only used by ACPI platforms. Signed-off-by: NRafael J.

This reverts commit 1c55f187. Ingo Brueckl was assuming that reverting to 1:1 mapping for chars >= 128 was not useful, but it happens to be: due to the limitations of the Linux console, when a blind user wants to read BIG5 on it, he has no other way than loading a font without SFM and let the 1:1 mapping permit the screen reader to get the BIG5 encoding.

Since commit 0a1c01c9 ("Make relatime default") when a file system is mounted explicitely with noatime it gets both the MNT_RELATIME and MNT_NOATIME bits set. This shows up like this in /proc/mounts: /dev/xxx /yyy ext3 rw,noatime,relatime,errors=continue,data=writeback 0 0 That looks strange. The VFS uses noatime in this case, but both flags are set. So it's more a cosmetic issue, but still better to fix. Cc: mjg@redhat.com Signed-off-by: NAndi Kleen <ak@linux.intel.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Typical message: 'lguest: unhandled trap 6 at 0x418726 (0x0)' vmlinux guests were broken by 4cd8b5e2 'lguest: use KVM hypercalls', which rewrites guest text from kvm hypercalls to trap 31. The Launcher mmaps the kernel image. The Guest executes and immediately faults in the first text page (read-only). Then it hits a hypercall, and we rewrite that hypercall, causing a copy-on-write. But the Guest pagetables still refer to the old page: we fault again, but as Host we see the hypercall already rewritten, and pass the fault back to the Guest. The Guest hasn't set up an IDT yet, so we kill it. This doesn't happen with bzImages: they unpack themselves and so the text pages are already read-write.
