If the disabled rb mask register is not properly initialized
program a sane default based on the number of RBs for the
asic. This avoids a potential divide by 0 when calculating

This fixes a regression introduced in commit 03ebebeb1 ("KVM: x86
emulator: Leave segment limit and attributs alone in real mode").
The mentioned commit changed the segment descriptors for both real mode
and VM86 to only update the segment base instead of creating a
completely new descriptor with limit 0xffff so that unreal mode keeps
working across a segment register reload.
This leads to an invalid segment descriptor in the eyes of VMX, which
seems to be okay for real mode because KVM will fix it up before the
next VM entry or emulate the state, but it doesn't do this if the guest
is in VM86, so we end up with:
KVM: entry failed, hardware error 0x80000021
Fix this by effectively reverting commit 03ebebeb1 for VM86 and leaving
it only in place for real mode, which is where it's really needed.

The s3c-fb driver requires header files from the samsung platforms
to find its platform_data definition, but this no longer works on
multiplatform kernels, so let's move the data into a new header
file under include/linux/platform_data.

In multiplatform configurations, we cannot include headers
provided by only the exynos platform. Fortunately a number
of drivers that include those headers do not actually need
them, so we can just remove the inclusions.

Note that the branch has dependencies to two other branches:
- omap-devel-b-for-3.10 from Paul to get the AM33xx missing
hwmod and thus avoid a regression with Santosh's hwmod
cleanup including in this DT series [1]. It avoids breaking
bisect if this series is merged before Paul's fixes.
- omap-for-v3.10/usb branch to avoid nasty merge conflict in
omap3.dtsi and omap4.dtsi due to the DTS patches contained
in the USB branch because of a screw up by the unnamed person
typing this signed tag based on Benoit's comments.

tlbmiss_handler_setup_pgd is run-time generated code and it was convenient
to pretend the symbol was an array in the generator but a function for
the users. LTO gcc won't tolerate this kind of lie anymore so solve the
problem through a cast and function pointer instead.

The code was written as it is because it's more expressive, a bit easier.
But it's always been dirty, if not a bug. But we can't cheat with LTO
compilers, so this results in:

The omapdrm driver currently takes a config/module arg to figure out the number
of crtcs it needs to create. We could create as many crtcs as there are overlay
managers in the DSS hardware, but we don't do that because each crtc eats up
one DSS overlay, and that reduces the number of planes we can attach to a single
crtc.
Since the number of crtcs may be lesser than the number of hardware overlay
managers, we need to figure out which overlay managers to use for our crtcs. The
current approach is to use pipe2chan(), which returns a higher numbered manager
for the crtc.
The problem with this approach is that it assumes that the overlay managers we
choose will connect to the encoders the platform's panels are going to use,
this isn't true, an overlay manager connects only to a few outputs/encoders, and
choosing any overlay manager for our crtc might lead to a situation where the
encoder cannot connect to any of the crtcs we have chosen. For example, an
omap5-panda board has just one hdmi output. If num_crtc is set to 1, with the
current approach, pipe2chan will pick up the LCD2 overlay manager, which cannot
connect to the hdmi encoder at all. The only manager that could have connected
to hdmi was the TV overlay manager.
Therefore, there is a need to choose our overlay managers keeping in mind the
panels we have on that platform. The new approach iterates through all the
available panels, creates encoders and connectors for them, and then tries to
get a suitable overlay manager to create a crtc which can connect to the
encoders.
We use the dispc_channel field in omap_dss_output to retrieve the desired
overlay manager's channel number, we then check whether the manager had already
been assigned to a crtc or not. If it was already assigned to a crtc, we assume
that out of all the encoders which intend use this crtc, only one will run at a
time. If the overlay manager wan't assigned to a crtc till then, we create a
new crtc and link it with the overlay manager.
This approach just looks for the best dispc_channel for each encoder. On DSS HW,
some encoders can connect to multiple overlay managers. Since we don't try
looking for alternate overlay managers, there is a greater possibility that 2
or more encoders end up asking for the same crtc, causing only one encoder to
run at a time.
Also, this approach isn't the most optimal one, it can do either good or bad
depending on the sequence in which the panels/outputs are parsed. The optimal
way would be some sort of back tracking approach, where we improve the set of
managers we use as we iterate through the list of panels/encoders. That's
something left for later.

When userspace calls SET_PLANE ioctl, drm core takes a reference of the fb and
passes control to the update_plane op defined by the drm driver.
In omapdrm, we have a worker thread which queues framebuffers objects received
from update_plane and displays them at the appropriate time.
It is possible that the framebuffer is destoryed by userspace between the time
of calling the ioctl and apply-worker being scheduled. If this happens, the
apply-worker holds a pointer to a framebuffer which is already destroyed.
Take an extra refernece/unreference of the fb in omap_plane_update() to prevent
this from happening. A reference is taken of the fb passed to update_plane(),
the previous framebuffer (held by plane->fb) is unreferenced. This will prevent
drm from destroying the framebuffer till the time it's unreferenced by the
apply-worker.
This is in addition to the exisitng reference/unreference in update_pin(),
which is taken for the scanout of the plane's current framebuffer, and an
unreference the previous framebuffer.

The omapdrm driver requires omapdss panel drivers to expose ops like detect,
set_timings and check_timings. These can be NULL for fixed panel DPI, DBI, DSI
and SDI drivers. At some places, there are no checks to see if the panel driver
has these ops or not, and that leads to a crash.
The following things are done to make fixed panels work:
- The omap_connector's detect function is modified such that it considers panel
types which are generally fixed panels as always connected(provided the panel
driver doesn't have a detect op). Hence, the connector corresponding to these
panels is always in a 'connected' state.
- If a panel driver doesn't have a check_timings op, assume that it supports the
mode passed to omap_connector_mode_valid(the 'mode_valid' drm helper function)
- The function omap_encoder_update shouldn't really do anything for fixed
resolution panels, make sure that it calls set_timings only if the panel
driver has one.

modeset_init iterates through all the registered omapdss devices and has some
initial checks to see if the panel has a driver and the required driver ops for
it to be usable by omapdrm.
The function bails out from modeset_init if a panel doesn't meet the
requirements, and stops the registration of the future panels and encoders which
come after it, that isn't the correct thing to do, we should go through the rest
of the panels. Replace the 'return's with 'continue's.

When the 1st rate control entry is a pre-HT rate we want to set
rts_cts_rate_idx "as the fastest basic rate that is not faster than the
data rate"(code comments).
But in case some bss allowed rate indexes are lower than the lowest bss
basic rate, if the rate control selects a rate among the formers for its
1st rate control entry, rts_cts_rate_idx remains 0 and is not a basic
rate index.
This commit sets rts_cts_rate_idx to the lowest bss basic rate index in
this situation.
Note that the code assumes that lowest indexes == lowest bitrates.

When not using DSI PLL to generate the pixel clock, but DSS FCK, the
possible pixel clock rates are rather limited. DSS FCK is currently used
on OMAP2 and OMAP3.
When using Beagleboard with a monitor that supports high resolutions,
the clock rates do not match (at least for me) for the monitor's pixel
clocks within the current threshold in the code, which is +/- 1MHz.
This patch widens the search up to +/- 15MHz. The search is done in
steps, i.e. it first tries to find a rather exact clock, than a bit less
exact, etc. so this should not change the cases where a clock was
already found.

DSS func clock is calculated with prate / div * m. However, the current
omapdss code calculates it with prate * m / div, which yields a slightly
different result when there's a remainder. For example, 432000000 / 14 *
2 = 61714284, but 432000000 * 2 / 14 = 61714285.
In addition to that, the clock framework wants the clock rate given with
clk_set_rate to be higher than the actual (truncated) end result. So, if
prate is 432000000, and div is 14, the real result is 30857142.8571...
We need to call clk_set_rate with 30857143, which gives us a clock of
30857142. That's why we need to use DIV_ROUND_UP() when calling
clk_set_rate.
This patch fixes the clock calculation.

Commit:
a8aed3e075 ("x86/mm/pageattr: Prevent PSE and GLOABL leftovers to confuse pmd/pte_present and pmd_huge")
introduced a valid fix but one location that didn't trigger the bug that
lead to finding those (small) problems, wasn't updated using the
right variable.
The wrong variable was also initialized for no good reason, that
may have been the source of the confusion. Remove the noop
initialization accordingly.
Commit a8aed3e075 also erroneously removed one canon_pgprot pass meant
to clear pmd bitflags not supported in hardware by older CPUs, that
automatically gets corrected by this patch too by applying it to the right
variable in the new location.

Documentation/kernel-parameters.txt and
Documentation/x86/x86_64/boot-options.txt contain virtually
identical text describing earlyprintk.
This consolidates the two copies and updates the documentation a
bit. No one ever documented the:
earlyprintk=serial,0x1008,115200
syntax, nor mentioned that ARM is now a supported earlyprintk
arch.

When compiling kernel with -jN (N > 1), all warning/error messages
printed while openssl is generating key pair may get mixed dots and
other symbols openssl sends to stderr. This patch makes sure openssl
logs go to default stdout.
Example of the garbage on stderr:

This adds a config option USB_DWC2_DEBUG_PERIODIC that allows debugging
output be suppressed for periodic transfers. This helps when debugging
non-periodic transfers while there are also periodic transfers going on
(both to make the debug output less polluted and to prevent all CPU time
going to debug messages).
In addition, a debug message from dwc2_hcd_is_status_changed is removed
entirely, since it often floods the log regardless of periodic
transfers.
