A long time ago, probably in 2002, one of the distros, or maybe more than
one, loaded block drivers prior to loading the SCSI mid layer. This meant
that the cciss driver, being a block driver, could not engage the SCSI mid
layer at init time without panicking, and relied on being poked by a
userland program after the system was up (and the SCSI mid layer was
therefore present) to engage the SCSI mid layer.
This is no longer the case, and cciss can safely rely on the SCSI mid
layer being present at init time and engage the SCSI mid layer straight
away. This means that users will see their tape drives and medium
changers at driver load time without need for a script in /etc/rc.d that
does this:
for x in /proc/driver/cciss/cciss*
do
echo "engage scsi" > $x
done
However, if no tape drives or medium changers are detected, the SCSI mid
layer will not be engaged. If a tape drive or medium change is later
hot-added to the system it will then be necessary to use the above script
or similar for the device(s) to be acceesible.

1) Anyone who has read access to loopdev has permission to call set_status
and may change important parameters such as lo_offset, lo_sizelimit and
so on, which contradicts to read access pattern and definitely equals
to write access pattern.
2) Add lo_offset over i_size check to prevent blkdev_size overflow.
##Testcase_bagin
#dd if=/dev/zero of=./file bs=1k count=1
#losetup /dev/loop0 ./file
/* userspace_application */
struct loop_info64 loinf;
fd = open("/dev/loop0", O_RDONLY);
ioctl(fd, LOOP_GET_STATUS64, &loinf);
/* Set offset to any value which is bigger than i_size, and sizelimit
* to nonzero value*/
loinf.lo_offset = 4096*1024;
loinf.lo_sizelimit = 1024;
ioctl(fd, LOOP_SET_STATUS64, &loinf);
/* After this loop device will have size similar to 0x7fffffffffxxxx */
#blockdev --getsz /dev/loop0

If read was not fully successful we have to fail whole bio to prevent
information leak of old pages
##Testcase_begin

losetup /dev/loop0 ./file -o 4096
truncate -s 0 ./file
# OOps loop offset is now beyond i_size, so read will silently fail.
# So bio's pages would not be cleared, may which result in information leak.

("block: check for proper length of iov entries earlier ...")
we still won't check for zero-length entries after an unaligned
entry. Remove the break-statement, so all entries are checked.

bdi_prune_sb() in bdi_unregister() attempts to removes the bdi links
from all super_blocks and then del_timer_sync() the writeback timer.
However, this can race with __mark_inode_dirty(), leading to
bdi_wakeup_thread_delayed() rearming the writeback timer on the bdi
we're unregistering, after we've called del_timer_sync().
This can end up with the bdi being freed with an active timer inside it,
as in the case of the following dump after the removal of an SD card.
Fix this by redoing the del_timer_sync() in bdi_destory().

This reverts commit a72c5e5eb738033938ab30d6a634b74d1d060f10.
The commit introduced alias for block devices which is intended to be
used during logging although actual usage hasn't been committed yet.
This approach adds very limited benefit (raw log might be easier to
follow) which can be trivially implemented in userland but has a lot
of problems.
It is much worse than netif renames because it doesn't rename the
actual device but just adds conveninence name which isn't used
universally or enforced. Everything internal including device lookup
and sysfs still uses the internal name and nothing prevents two
devices from using conflicting alias - ie. sda can have sdb as its
alias.
This has been nacked by people working on device driver core, block
layer and kernel-userland interface and shouldn't have been
upstreamed. Revert it.

get_context_loss_count functions return context loss count as u32, and
zero means an error. However, zero is also returned when context has
never been lost and could also be returned when the context loss count
has wrapped and goes to zero.
Change the functions to return an int, with negative value meaning an
error.
OMAP HSMMC code uses omap_pm_get_dev_context_loss_count(), but as the
hsmmc code handles the returned value as an int, with negative value
meaning an error, this patch actually fixes hsmmc code also.

Commit d6504acd2125984c61dce24727dd3842d0144015 ("OMAP2+: hwmod:
remove OMAP_CHIP*") tests the inverse condition of what it should be
testing for the return value from omap_hwmod_register(). This causes
several IP blocks to not be registered on several OMAP3 family devices.
Fixing that bug also unmasked another bug, originally reported by
Chase Maupin <chase.maupin@ti.com> and then subsequently by Abhilash K
V <abhilash.kv@ti.com>, which caused SmartReflex IP blocks to be
registered on SoCs that don't support them.
Thanks to Russell King - ARM Linux <linux@arm.linux.org.uk> for comments
on a previous version of the patch.

Commit 4d17aeb1c5b2375769446d13012a98e6d265ec13 ("OMAP: I2C: split
device registration and convert OMAP2+ to omap_device") makes
omap2_i2c_add_bus() return a pointer to an omap_device instead on
success instead of 0.
This breaks the omap_register_i2c_bus() ABI and results in the igep0020
board code detecting an I2C bus registration error when there is none.
Fix the problem by using PTR_RET() instead of PTR_ERR() in
omap2_i2c_add_bus().

Based on the documents that I have here, there doesn't appear to be an
equivalent to erratum i443 for OMAP3630, so restrict this one to OMAP34xx
chips.
Also, explicitly restrict this erratum to EMU and HS devices.

The way that we detect which OMAP3 chips support I/O wakeup and
software I/O chain clock control is broken.
Currently, I/O wakeup is marked as present for all OMAP3 SoCs other
than the AM3505/3517. The TI81xx family of SoCs are at present
considered to be OMAP3 SoCs, but don't support I/O wakeup. To resolve
this, convert the existing blacklist approach to an explicit,
whitelist support, in which only SoCs which are known to support I/O
wakeup are listed. (At present, this only includes OMAP34xx,
OMAP3503, OMAP3515, OMAP3525, OMAP3530, and OMAP36xx.)
Also, the current code incorrectly detects the presence of a
software-controllable I/O chain clock on several chips that don't
support it. This results in writes to reserved bitfields, unnecessary
delays, and console messages on kernels running on those chips:
http://www.spinics.net/lists/linux-omap/msg58735.html
Convert this test to a feature test with a chip-by-chip whitelist.

The context lost count is modified in omap_sram_idle() path when
pwrdm_post_transition() is called. But pwrdm_post_transition() is called
only after omap_gpio_resume_after_idle() is called. Correct this so that
context lost count is modified before calling omap_gpio_resume_after_idle().
This would be useful when OMAP GPIO save/restore context is called by
the OMAP GPIO driver itself.

The OMAP36xx and OMAP4xxx DPLLs have a different internal reference
clock frequency (fint) operating range than OMAP3430. Update the
dpll_test_fint() function to check for the correct frequency ranges
for OMAP36xx and OMAP4xxx.
For OMAP36xx and OMAP4xxx devices, DPLLs fint range is 0.5MHz to
2.5MHz for j-type DPLLs and otherwise it is 32KHz to 52MHz for all
other DPLLs.

The parent clock of the OCP_ABE_ICLK is the AESS_FCLK and the
parent clock of the AESS_FCLK is the ABE_FCLK...
ABE_FCLK --> AESS_FCLK --> OCP_ABE_ICLK
The AESS_FCLK and OCP_ABE_ICLK clocks both have dividers which
determine their operational frequency. However, the dividers for
the AESS_FCLK and OCP_ABE_ICLK are controlled via a single bit,
which is the CM1_ABE_AESS_CLKCTRL[24] bit. When this bit is set to
0, the AESS_FCLK divider is 1 and the OCP_ABE_ICLK divider is 2.
Similarly, when this bit is set to 1, the AESS_FCLK divider is 2
and the OCP_ABE_ICLK is 1.
The above relationship between the AESS_FCLK and OCP_ABE_ICLK
dividers ensure that the OCP_ABE_ICLK clock is always half the
frequency of the ABE_CLK...
OCP_ABE_ICLK = ABE_FCLK/2
The divider for the OCP_ABE_ICLK is currently missing so add a
divider that will ensure the OCP_ABE_ICLK frequency is always half
the ABE_FCLK frequency.

OMAP4460 specific clocks are not getting added as the
cpu_is_omap44xx is choosing only OMAP4430 specific clock nodes.
Changing it to add to OMAP4460 specific clocks also.
This is clocks are required of temperature sensor.

This is a continuation of Mike Turquette's patch "OMAP3+: use
DPLL's round_rate when setting rate".
omap3_noncore_dpll_set_rate() and omap3_noncore_dpll_enable() call
omap2_get_dpll_rate() explicitly. It may be necessary for some
DPLLs to use a different function and so use the DPLLs recalc()
function pointer instead.
An example is the DPLL_ABE on OMAP4 which can have a 4X multiplier
in addition to the usual MN multipler and dividers and therefore
uses a different round_rate and recalc function.

The rounded rate can differ from target rate, so to better reflect
reality set clk->rate equal to the rounded rate when setting DPLL frequency.
This avoids issues where the DPLL frequency is slightly different than what
debugfs clock tree reports using the old target rate.
An example of a clock that requires this is DPLL_ABE on OMAP4 which
can have a 4x multiplier on top of the usual MN dividers depending on
register settings. This requires a special round_rate function that
might yield a rate different from the initial target.

omap3_noncore_dpll_set_rate uses omap2_dpll_round_rate explicitly. Instead
use the struct clk pointer's round_rate function to allow for DPLL's with
special needs.

OMAP4 DPLL_ABE can enable a 4X multipler on top of the normal MN multipler
and divider. This is achieved by setting CM_CLKMODE_DPLL_ABE.DPLL_REGM4XEN
bit in CKGEN module of CM1. From the OMAP4 TRM:
Fdpll = Fref x 2 x (4 x M/(N+1)) in case REGM4XEN bit field is set (only
applicable to DPLL_ABE).
Add new round_rate() and recalc() functions for OMAP4, that check the
setting of REGM4XEN bit and handle this appropriately. The new functions
are a simple wrapper on top of the existing omap2_dpll_round_rate() and
omap2_dpll_get_rate() functions to handle the REGM4XEN bit.
The REGM4XEN bit is only implemented for the ABE DPLL on OMAP4 and so
only dpll_abe_ck uses omap4_dpll_regm4xen_round_rate() and
omap4_dpll_regm4xen_recalc() functions.

Mountpoint crossing is similar to following procfs symlinks - we do
not get ->d_revalidate() called for dentry we have arrived at, with
unpleasant consequences for NFS4.
Simple way to reproduce the problem in mainline:
cat >/tmp/a.c <<'EOF'
#include <unistd.h>
#include <fcntl.h>
#include <stdio.h>
main()
{
struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
if (fcntl(0, F_SETLK, &fl))
perror("setlk");
}
EOF
cc /tmp/a.c -o /tmp/test
then on nfs4:
mount --bind file1 file2
/tmp/test < file1 # ok
/tmp/test < file2 # spews "setlk: No locks available"...
What happens is the missing call of ->d_revalidate() after mountpoint
crossing and that's where NFS4 would issue OPEN request to server.
The fix is simple - treat mountpoint crossing the same way we deal with
following procfs-style symlinks. I.e. set LOOKUP_JUMPED...

In the old --stdio interface the annotation is done just after one
selects a symbol, while in --tui, now the default when the required libs
are installed, we annotate all symbols with samples so that when
annotation is asked we see what happened recently on that symbol.
To achieve that the --stdio variant checks if the hist_entry being
processed is the one selected by the user via the 's' hotkey. What
happens now that we share the hist_entry abstractions with 'perf report'
is that for minimizing locking contention multiple rb_trees are used,
one for collecting the samples and other to browse/show them after
resorting it by number of samples and decay them, which is done
periodically.
So the simple test in record_precise_ip doesn't work as we move
hist_entries between those rb_trees. To fix it just check that the
underlying struct symbol associated with those hist_entries is the same.

It makes sense for the stdio where we can't navigate to the other pages.
On the TUI it breaks as soon as we navigate to other pages that have,
DSOs with longer names than the ones on the first page.
