Pull misc vfs updates from Al Viro:
"All kinds of stuff. That probably should've been 5 or 6 separate
branches, but by the time I'd realized how large and mixed that bag
had become it had been too close to -final to play with rebasing.Some fs/namei.c cleanups there, memdup_user_nul() introduction and
switching open-coded instances, burying long-dead code, whack-a-mole
of various kinds, several new helpers for ->llseek(), assorted
cleanups and fixes from various people, etc.One piece probably deserves special mention - Neil's
lookup_one_len_unlocked(). Similar to lookup_one_len(), but gets
called without ->i_mutex and tries to avoid ever taking it. That, of
course, means that it's not useful for any directory modifications,
but things like getting inode attributes in nfds readdirplus are fine
with that. I really should've asked for moratorium on lookup-related
changes this cycle, but since I hadn't done that early enough... I
*am* asking for that for the coming cycle, though - I'm going to try
and get conversion of i_mutex to rwsem with ->lookup() done under lock
taken shared.There will be a patch closer to the end of the window, along the lines
of the one Linus had posted last May - mechanical conversion of
->i_mutex accesses to inode_lock()/inode_unlock()/inode_trylock()/
inode_is_locked()/inode_lock_nested(). To quote Linus back then:-----
| This is an automated patch using
|
| sed 's/mutex_lock(&\(.*\)->i_mutex)/inode_lock(\1)/'
| sed 's/mutex_unlock(&\(.*\)->i_mutex)/inode_unlock(\1)/'
| sed 's/mutex_lock_nested(&\(.*\)->i_mutex,[ ]*I_MUTEX_\([A-Z0-9_]*\))/inode_lock_nested(\1, I_MUTEX_\2)/'
| sed 's/mutex_is_locked(&\(.*\)->i_mutex)/inode_is_locked(\1)/'
| sed 's/mutex_trylock(&\(.*\)->i_mutex)/inode_trylock(\1)/'
|
| with a very few manual fixups
-----I'm going to send that once the ->i_mutex-affecting stuff in -next
gets mostly merged (or when Linus says he's about to stop taking
merges)"* 'work.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (63 commits)

hwrng kthread can be waiting via hwrng_fillfn for some data from a rng

In order to allow panic actions to be processed, the ipmi watchdog
driver sets a new timeout value on panic. The 255s timeout
was designed to allow kdump and others actions on panic, as in
http://lkml.iu.edu/hypermail/linux/kernel/0711.3/0258.htmlThis is counter-intuitive for a end-user who sets watchdog timeout
value to something like 30s and who expects BMC to reset the system
within 30s of a panic.This commit allows user to configure the timeout on panic.

__compat_only_sysfs_link_entry_to_kobj() was unconditionally called for
TPM1 chips, which caused crash on Acer C720 laptop where DSM for the
ACPI object did not exist.There are two reasons for unwanted behavior:
* The code did not check whether
__compat_only_sysfs_link_entry_to_kobj() returned -ENOENT. This is
OK. It just meanst that ppi is not available.
* The code did not clean up properly. Compat link should added only
after all other init is done.This patch sorts out these issues.

This patch replaces timeval with timespec64 as 32 bit 'struct timeval'
will not give current time beyond 2038.The patch changes the code to use ktime_get_real_ts64() which returns
a 'struct timespec64' instead of do_gettimeofday() which returns a
'struct timeval'This patch also alters the format string in pr_info() for now.tv_sec
to incorporate 'long long' on 32 bit architectures.Signed-off-by: Amitoj Kaur Chawla

Add Device Tree support for the driver. The Pseudo Random Number
Generator module is the same in almost all of Exynos SoCs, since
Exynos4210 (however the tests were done only on Trats2 board with
Exynos4412). There are some differences on newer Exynos Octa
(Exynos542x) SoCs.Signed-off-by: Krzysztof Kozlowski

After suspend to RAM the device stopped to work with ETIMEDOUT error:
$ dd if=/dev/hwrng of=/dev/null bs=1 count=16
dd: reading `/dev/hwrng': Connection timed outIn the STATUS register the bits #5 (PRNG_DONE) and #1
(SEED_SETTING_DONE) were not set. Instead PRNG_ERROR (seventh bit) was
high.After each system suspend initialize the seed to fix the error.

Currently this driver calls pm_runtime_get_sync() rampantly
but never puts anything back. This makes it impossible for the
device to autosuspend properly; it will remain fully active
after the first use.Fix in the obvious way.

The base pointer for the event log is allocated in the local
kernel (in prom_instantiate_sml()), therefore it is already in
the host's endian byte order and requires no conversion.The content of the 'basep' pointer in read_log() stores the
base address of the log. This patch ensures that it is correctly
implemented.Signed-off-by: Hon Ching(Vicky) Lo

This patch makes the code endianness independent. We defined a
macro do_endian_conversion to apply endianness to raw integers
in the event entries so that they will be displayed properly.
tpm_binary_bios_measurements_show() is modified for the display.Signed-off-by: Hon Ching(Vicky) Lo
