If CPU 0's stack grows to large, it will overflow into CPU 1's stack.
If CPU 0 is handling the interrupt then CPU 1 should be in an idle loop.
When the stack overflow occurs it will override the return pointer for
CPU 1, so when CPU 0 unlocks the SMI lock, CPU 1 will attempt to return
to a random address.
This method is not foolproof. If code allocates some stack variables
that overlap with the canary, and if the variables are never set, then
the canary will not be overwritten, but it will have been skipped. We
could mitigate this by adding a larger canary value if we wanted.
I chose to use the stack bottom pointer value as the canary value
because:
* It will change per CPU stack.
* Doesn't require hard coding a value that must be shared between the
.S and .c.
* Passing the expected canary value as a parameter felt like overkill.
We can explore adding other methods of signaling that a stack overflow
had occurred in a follow up. I limited die() to debug only because
otherwise it would be very hard to track down.
TEST=built on grunt with a small and large stack size. Then verified
that one causes a stack overflow and the other does not.

Call to pmc_disable_all_gpe is required before enabling SMIs to ensure
that we do not end up in a recursive SMI handler loop as mentioned in
change 74145f7 (intel/common/pmc: Disable all GPEs during
pmc_init). Thus, this call was added at the end of
pmc_fill_power_state as we want to ensure that all the GPE registers
are backed up before being cleared for identifying the wake source in
ramstage.
This resulted in a side-effect on APL where pmc_fixup_power_state was
called much later in the boot process. Even though we have got rid of
pmc_fixup_power_state, this change moves the call to
pmc_disable_all_gpe to happen just before enabling SMIs. This helps to
keep the disabling of GPEs logically before the enabling of SMIs and
any clean ups that happen in pmc or soc-specific code should not
affect the state of GPEs.

On APL, call to pmc_fixup_power_state was added because GPE0_EN
registers did not have the right bits set on resume from S3 -- this
was a result of GPE_CFG registers getting reset to their default state
on resume. GPE_CFG registers are programmed as part of pmc_gpe_init
which was previously done only in ramstage.
However, with change a673d1c (soc/intel/apollolake: Initialize GPEs in
bootblock), call to pmc_gpe_init was added to bootblock which means
that GPE_CFG registers will have the right state by the time control
reaches romstage where pmc_fill_power_state is called. Thus, call to
pmc_fixup_power_state is totally redundant and in fact leads to
side-effects because of the call to pmc_disable_all_gpe at the end of
pmc_fill_power_state.

Disabling the MMU with proper cache behavior is a bit tricky on ARM64:
you can flush the cache first and then disable the MMU (like we have
been doing), but then you run the risk of having new cache lines
allocated in the tiny window between the two, which may or may not
become a problem when those get flushed at a later point (on some
platforms certain memory regions "go away" at certain points in a way
that makes the CPU very unhappy if it ever issues a write cycle to
them again afterwards).
The obvious alternative is to first disable the MMU and then flush the
cache, ensuring that every memory access after the flush already has the
non-cacheable attribute. But we can't just flip the order around in the
C code that we have because then those accesses in the tiny window
in-between will go straight to memory, so loads may yield the wrong
result or stores may get overwritten again by the later cache flush.
In the end, this all shouldn't really be a problem because we can do
both operations purely from registers without doing any explicit memory
accesses in-between. We just have to reimplement the function in
assembly to make sure the compiler doesn't insert any stack accesses at
the wrong points.

Recent patches in coreboot have fixed the freeze issues related to the
use of me_cleaner on Nehalem.
However, at least on the Lenovo X201, with me_cleaner some PCIe devices
(like the SATA and USB controllers) disappear. In particular, setting
the AltMeDisable bit ("-S" or "-s" flag) makes them disappear
completely, while unsetting it makes them disappear only during cold
boots.
This kind of behaviour was already observed by Youness Alaoui on the
Purism Librem laptops ([1]), and it seems related to some required
board-specific PCIe configuration in the ME's MFS partition.
For this reason, on the Lenovo X201, "-w EFFS" has been added to the
me_cleaner arguments, which whitelists the MFS-equivalent partition for
ME generation 2. This fixes all the issues, and the PCIe devices work as
expected.
