Blackfin: fix relocation errors with large initramfs images

Since we are now discarding .exit.text at runtime instead of link time, we
need to place all .text sections ahead of the .data sections.  Otherwise,
a really large attached initramfs may cause link errors as it pushes the
PC relative relocations behind the limits of the Blackfin ISA (~16meg).
The instructions in the .exit.text are unable to call back into the .text
sections leading to a link failure.

SMP systems require per-cpu local clock event devices in order to enable
HRT support.  One a BF561, we can use local core timer for this purpose.
Originally, there was one global core-timer clock event device set up for
core A.

To accomplish this feat, we need to split the gptimer0/core timer logic
so that each is a standalone clock event.  There is no requirement that
we only have one clock event source anyways.  Once we have this, we just
define per-cpu clock event devices for each local core timer.

Typically the inode mutex is used to serialize updates
to the vfs inode, but grabbing the inode mutex in
sysfs_permission and sysfs_getattr causes deadlocks,
because sometimes the vfs calls those operations with
the inode mutex held.  Therefore sysfs  can not use the
inode mutex to serial updates to the vfs inode.

The sysfs_mutex is acquired in all of the routines
where sysfs updates the vfs inode, and with a small
change we can consistently protext sysfs vfs inode
updates with the sysfs_mutex. To protect the sysfs
vfs inode updates with the sysfs_mutex simply requires
extending the scope of sysfs_mutex in sysfs_setattr
over inode_setattr, and over inode_change_ok (so we
have an unchanging inode when we perform the check).

sysdev: fix up the probe/release attributes

These should be sysdev attributes, not class attributes.  This patch
should resolve the problem.

Thanks to Stephen Rothwell for pointing out the problem.

kobject: Constify struct kset_uevent_ops

Constify struct kset_uevent_ops.

This is part of the ops structure constification
effort started by Arjan van de Ven et al.

Benefits of this constification:

 * prevents modification of data that is shared
   (referenced) by many other structure instances
   at runtime

 * detects/prevents accidental (but not intentional)

   read-only kernel data at runtime

 * potentially better optimized code as the compiler

14 years agosysfs: Cache the last sysfs_dirent to improve readdir scalability v2

sysfs: Cache the last sysfs_dirent to improve readdir scalability v2

When sysfs_readdir stops short we now cache the next
sysfs_dirent to return to user space in filp->private_data.
There is no impact on the rest of sysfs by doing this and
in the common case it allows us to pick up exactly where
we left off with no seeking.

Additionally I drop and regrab the sysfs_mutex around
filldir to avoid a page fault abritrarily increasing the
hold time on the sysfs_mutex.

v2: Returned to using INT_MAX as the EOF condition.
    seekdir is ambiguous unless all directory entries have
    a unique f_pos value.
