ARM: Fix errata 411920 workarounds

Errata 411920 indicates that any "invalidate entire instruction cache"
operation can fail if the right conditions are present.  This is not
limited just to those operations in flush.c, but elsewhere.  Place the
workaround in the already existing __flush_icache_all() function
instead.

ocfs2: return f_fsid info in ocfs2_statfs()

Currently the f_fsid of struct kstatfs returned from ocfs2_statfs() is
undefined (vfs layer fills in 0 as default). Since in some conditions,
f_fsid value might be used in a (f_fsid, ino) pair to uniquely identify
a file, ocfs2 should return a unique defined f_fsid value from
ocfs2_statfs().

Because uuid_str is the same on big or litlle endian machine, it's
endian consistent to use osb->uuid_str to generate f_fsid value.

e100: e100_phy_init() isolates selected PHY, causes 10 second boot delay

A change in how PHYs are electrically isolated caused all PHYs to be
isolated followed by reverting that isolation for the selected PHY.
Unfortunately, isolating the selected PHY for even a short period of
time can result in DHCP negotiation taking more than 10 seconds on certain
embedded configurations delaying boot time as reported by Bernhard Kaindl.
This patch reverts the change to how PHYs are isolated yet still works
around the issue for 82552 needing the selected PHY's BMCR register to
be written after the unused PHYs are isolated.  This code is moved below
the setting of nic->phy ID in order to do the 82552-specific workaround.

e1000e: config PHY via software after resets

On PCH-based (82577/82578) and some ICH8-based parts (82566) there is an
issue with the hardware automatically configuring the PHY with contents
from the EEPROM after the PHY is reset, so do the configuration by the
driver instead.  This was already similarly done for some 82566 parts in
e1000_phy_hw_reset_ich8lan() but needs to be done after other resets,
so move the PHY configuration code to its own function and call after
all PHY resets.

e1000e: rework disable K1 at 1000Mbps for 82577/82578

This patch reworks a previous workaround (commit 7d3cabbcc) for an issue
in hardware where noise on the interconnect between the MAC and PHY could
be generated by a lower power mode (K1) at 1000Mbps resulting in bad
packets.  Disable K1 while at 1000 Mbps but keep it enabled for 10/100Mbps
and when the cable is disconnected.  The original version of this
workaround was found to be incomplete.

xfs: free temporary cursor in xfs_dialloc

Commit bd169565993b39b9b4b102cdac8b13e0a259ce2f seems
to have a slight regression where this code path:

    if (!--searchdistance) {
        /*
         * Not in range - save last search
         * location and allocate a new inode
         */
        ...
        goto newino;
    }

doesn't free the temporary cursor (tcur) that got dup'd in
this function.

This leaks an item in the xfs_btree_cur zone, and it's caught
on module unload:

===========================================================
BUG xfs_btree_cur: Objects remaining on kmem_cache_close()
-----------------------------------------------------------

It seems like maybe a single free at the end of the function might
be cleaner, but for now put a del_cursor right in this code block
similar to the handling in the rest of the function.

xfs: fix xfs_quota remove error

The xfs_quota returns ENOSYS when remove command is executed.
Reproducable with following steps.

    # mount -t xfs -o uquota /dev/sda7 /mnt/mp1
    # xfs_quota -x -c off -c remove
    XFS_QUOTARM: Function not implemented.

The remove command is allowed during quotaoff, but xfs_fs_set_xstate()
checks whether quota is running, and it leads to ENOSYS.

To solve this problem, add a check for X_QUOTARM.

ALSA: sound: Move dereference after NULL test and drop unnecessary NULL tests

In pcm.c, if the NULL test on pcm is needed, then the dereference should be
after the NULL test.

In dummy.c and ali5451.c, the context of the calls to
snd_card_dummy_new_mixer and snd_ali_free_voice show that dummy and pvoice,
respectively cannot be NULL.

A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):

// <smpl>
@match exists@
expression x, E;
identifier fld;
@@

* x->fld
  ... when != \(x = E\|&x\)
* x == NULL

ALSA: sound/parisc: Move dereference after NULL test

If the NULL test on h is needed in snd_harmony_mixer_init, then the
dereference should be after the NULL test.

Actually, there is a sequence of calls: snd_harmony_create, then
snd_harmony_pcm_init, and then snd_harmony_mixer_init.  snd_harmony_create
initializes h, but may indeed leave it as NULL.  There was no NULL test at
the beginning of snd_harmony_pcm_init, so I have added one.  The NULL test
in snd_harmony_mixer_init is then not necessary, but in case the ordering
of the calls changes, I have left it, and moved the dereference after it.
