The mpc836x_mds platform has been broken since the commit
6fe3264945
"netdev/phy: Use mdiobus_read() so that proper locks are taken"
which caused the fsl_pq_mdio TBI autoprobe to oops. The oops
was "fixed" in commit 28d8ea2d56
"fsl_pq_mdio: Clean up tbi address configuration"
by simply removing the the autoscan code, and making tbi nodes
mandatory. Some of the newer reference platforms were updated
to have tbi nodes in 220669495b
"powerpc: Add TBI PHY node to first MDIO bus"
but the older mpc836x didn't get one and hence was just failing
with -EBUSY as follows:
fsl-pq_mdio: probe of e0102120.mdio failed with error -16
...
net eth0: Could not attach to PHY
eth0: Cannot initialize PHY, aborting.
Add a TBI node and use the 1st free address for it.

When the P1022's DIU video controller is active, the pixis must be accessed
in "indirect" mode, which uses localbus chip select addresses.
Switching between the DVI and LVDS monitor ports is handled by the pixis,
so that switching needs to be done via indirect mode.
This has the side-effect of no longer requiring U-Boot to enable the DIU.
Now Linux can enable the DIU all by itself.

The Freescale P1022 has a unique pin muxing "feature" where the DIU video
controller's video signals are muxed with 24 of the local bus address signals.
When the DIU is enabled, the bulk of the local bus is disabled, preventing
access to memory-mapped devices like NOR flash and the pixis FPGA.
Therefore, if the DIU is going to be enabled, then memory-mapped devices on
the localbus, like NOR flash, need to be disabled.
This also means that the localbus is not a 'simple-bus' any more, so remove
that string from the compatible node.

This is here most likely since the FSL bsp. Back in the FSL bsp it was
set to 50Mhz and working. However the driver divided the SoC freq. only
by 2. According to the TRM the platform clock (which the manual refers
in its formula) is the system clock divided by two. So in the end it has
to divide by 4 and this is what the fsl-spi driver in tree is doing.
Since then the flash is not wokring I guess. After chaning the freq from
50Mhz to 40Mhz like others do then I can access the flash.

As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block
is pending in the shared queue.
Also, use the new helper function introduced in commit 5e6292c0f2
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate
code across architectures. In the past some architectures got this
code wrong, so using this helper function should stop that from
happening again.

When a machine boots up, the TSC generally gets reset. However,
when kexec is used to boot into a kernel, the TSC value would be
carried over from the previous kernel. The computation of
cycns_offset in set_cyc2ns_scale is prone to an overflow, if the
machine has been up more than 208 days prior to the kexec. The
overflow happens when we multiply *scale, even though there is
enough room to store the final answer.
We fix this issue by decomposing tsc_now into the quotient and
remainder of division by CYC2NS_SCALE_FACTOR and then performing
the multiplication separately on the two components.
Refactor code to share the calculation with the previous
fix in __cycles_2_ns().
