This patch adds minimal support and build configuration for TI8148 EVM. Also
adds support for low level debugging on UART1 console on the EVM.
Note that existing TI8168 EVM file (board-ti8168evm.c) is updated with machine
info for TI8148 EVM.

This patch updates existing macros, functions used for TI816X, to enable
addition of other SoCs belonging to TI81XX family (e.g., TI814X).
The approach taken is to use TI81XX/ti81xx for code/data going to be common
across all TI81XX devices.
cpu_is_ti81xx() is introduced to handle code common across TI81XX devices.
In addition, ti8168_evm_map_io() is now replaced with ti81xx_map_io() and moved
in mach-omap2/common.c as same will be used for TI814X and is not board

Signed-off-by: Tony Lindgren <tony@atomide.com>
This patch updates the common platform files with AM335X device
support (AM33XX family).
The approach taken in this patch is,
AM33XX device will be considered as OMAP3 variant, and a separate
SoC class created for AM33XX family of devices with a subclass type
for AM335X device, which is newly added device in the family.
This means, cpu_is_omap34xx(), cpu_is_am33xx() and cpu_is_am335x()
checks will return success on AM335X device.
A kernel config option CONFIG_SOC_OMAPAM33XX is added under OMAP3
to include support for AM33XX build.
Also, cpu_mask and RATE_IN_XXX flags have crossed 8 bit hence
struct clksel_rate.flags, struct prcm_config.flags and cpu_mask
are changed to u16 from u8.

(2) Only events actually used by Linux are described.
(3) Where possible, architected events are used in preference to

The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned,
but not 64-bit aligned. The dqc_bitmap is accessed by ocfs2_set_bit(),
ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit(). These
are wrapper macros for ext2_*_bit() which need to take an unsigned long
aligned address (though some architectures are able to handle unaligned
address correctly)
So some 64bit architectures may not be able to access the dqc_bitmap
correctly.
This avoids such unaligned access by using another wrapper functions for
ext2_*_bit(). The code is taken from fs/ext4/mballoc.c which also need to
handle unaligned bitmap access.

Commit 4a54c8c16 introduced raid-repair, killing the individual
readpage_io_failed_hook entries from inode.c and disk-io.c. Commit
4bb31e92 introduced new readahead code, adding a readpage_io_failed_hook to
disk-io.c.
The raid-repair commit had logic to disable raid-repair, if
readpage_io_failed_hook is set. Thus, the readahead commit effectively
disabled raid-repair for meta data.
This commit changes the logic to always attempt raid-repair when needed and
call the readpage_io_failed_hook in case raid-repair fails. This is much
more straight forward and should have been like that from the beginning.

The SWP instruction is deprecated on ARMv6 and with ARMv7 it will be
UNDEFINED when CONFIG_SWP_EMULATE is selected. In this case, probing a
SWP instruction will cause an oops when the kprobes emulation code
executes an undefined instruction.
As the SWP instruction should be rare or non-existent in kernels for
ARMv6 and later, we can simply avoid these problems by not allowing
probing of these.

There is a kprobes testcase for the instruction "strd r2, [r3], r4".
This has unpredictable behaviour as it uses r3 for register writeback
addressing and also stores it to memory.
On a cortex A9, this testcase would fail because the instruction writes
the updated value of r3 to memory, whereas the kprobes emulation code
writes the original value.
Fix this by changing testcase to used r5 instead of r3.

We test whether a block group has enough free space to hold the
requested block, but when we're doing clustered allocation, we can
save some cycles by testing whether it has enough room for the cluster
upfront, otherwise we end up attempting to set up a cluster and
failing. Only in the NO_EMPTY_SIZE loop do we attempt an unclustered
allocation, and by then we'll have zeroed the cluster size, so this
patch won't stop us from using the block group as a last resort.

The field that indicates the size of the largest contiguous chunk of
free space in the cluster is not initialized when setting up bitmaps,
it's only increased when we find a larger contiguous chunk. We end up
retaining a larger value than appropriate for highly-fragmented
clusters, which may cause pointless searches for large contiguous
groups, and even cause clusters that do not meet the density
requirements to be set up.

We're failing to create clusters with bitmaps because
setup_cluster_no_bitmap checks that the list is empty before inserting
the bitmap entry in the list for setup_cluster_bitmap, but the list
field is only initialized when it is restored from the on-disk free
space cache, or when it is written out to disk.
Besides a potential race condition due to the multiple use of the list
field, filesystem performance severely degrades over time: as we use
up all non-bitmap free extents, the try-to-set-up-cluster dance is
done at every metadata block allocation. For every block group, we
fail to set up a cluster, and after failing on them all up to twice,
we fall back to the much slower unclustered allocation.
To make matters worse, before the unclustered allocation, we try to
create new block groups until we reach the 1% threshold, which
introduces additional bitmaps and thus block groups that we'll iterate
over at each metadata block request.
To reproduce this bug:
# dd if=/dev/zero of=img bs=1M count=256
# mkfs.btrfs img
# losetup -r /dev/loop1 img
# mount /dev/loop1 /mnt
OOPS!!
It triggered BUG_ON(!nr_devices) in btrfs_calc_avail_data_space().
To fix this, instead of checking write-only devices, we check all open
deivces:
