The conditions that one specific PE's frozen count exceeds the maximal
allowed times (EEH_MAX_ALLOWED_FREEZES) and it's in isolated or recovery
state indicate the PE was removed permanently implicitly. The patch
introduces flag EEH_PE_REMOVED to indicate that explicitly so that we
don't depend on the fixed maximal allowed times, which can be varied as
we do in subsequent patch.
Flag EEH_PE_REMOVED is expected to be marked for the PE whose frozen
count exceeds the maximal allowed times, or just failed from recovery.

PE#0 should be regarded as valid for P7IOC, while it's invalid for
PHB3. The patch adds flag EEH_VALID_PE_ZERO to differentiate those
two cases. Without the patch, we possibly see frozen PE#0 state is
cleared without EEH recovery taken on P7IOC as following kernel logs
indicate:

When calling to early_setup(), we pick "boot_paca" up for the master CPU
and initialize that with initialise_paca(). At that point, the SLB
shadow buffer isn't populated yet. Updating the SLB shadow buffer should
corrupt what we had in physical address 0 where the trap instruction is
usually stored.
This hasn't been observed to cause any trouble in practice, but is
obviously fishy.

Currently, all non-dot symbols are being treated as function descriptors
in ABIv1. This is incorrect and is resulting in perf probe not working:
# perf probe do_fork
Added new event:
Failed to write event: Invalid argument
Error: Failed to add events.
# dmesg | tail -1
[192268.073063] Could not insert probe at _text+768432: -22
perf probe bases all kernel probes on _text and writes,
for example, "p:probe/do_fork _text+768432" to
/sys/kernel/debug/tracing/kprobe_events. In-kernel, _text is being
considered to be a function descriptor and is resulting in the above
error.
Fix this by changing how we lookup symbol addresses on ppc64. We first
check for the dot variant of a symbol and look at the non-dot variant
only if that fails. In this manner, we avoid having to look at the
function descriptor.
While at it, also separate out how this works on ABIv2 where
we don't have dot symbols, but need to use the local entry point.

Once upon a time, at least 9 years ago (< 2.6.12), _TIF_SYSCALL_T_OR_A
meant "TRACE or AUDIT". But these days it means TRACE or AUDIT or
SECCOMP or TRACEPOINT or NOHZ.

When IOMMU bypass is enabled, a PCI device can read and write memory
that was not mapped by the driver without causing an EEH. That might
cause memory corruption, for example.
When we disable bypass, DMA reads and writes to addresses not mapped by
the IOMMU will cause an EEH, allowing us to debug such issues.

The current handling of EPOW_SHUTDOWN_ON_UPS event does not shutdown the
system after logging the message. All the events of EPOW_SYSTEM_SHUTDOWN
action code (EPOW_SHUTDOWN_ON_UPS is a part of it) must initiate system
shutdown as per the SPAPR spec. If the LPAR does not shutdown after
receiving this rtas based event, it will expose itself to a forced
abrupt shutdown initiated by the platform firmware. This patch fixes the
situation.

We have two arrays in kvm_host_state that contain register values for
the PMU. Currently we only create an asm-offsets symbol for the base of
the arrays, and do the array offset in the assembly code.
Creating an asm-offsets symbol for each field individually makes the
code much nicer to read, particularly for the MMCRx/SIxR/SDAR fields, and
might have helped us notice the recent double restore bug we had in this
code.

Moving config DTL up so it is below config PPC_SPLPAR means that
menuconfig will show config DTL nicely indented right below config
PPC_SPLPAR when PPC_SPLPAR is enabled.
To contrast that, right now if I enable PPC_SPLPAR in menuconfig, all I
can immediately tell is that "something showed up further down the list
where I wasn't looking", and I end up having to toggle the option a few
times to figure out what showed up, or look at the KConfig to find out
that config DTL depends on config PPC_SPLPAR.

The __ldcw macro has a problem when its argument needs to be reloaded from
memory. The output memory operand and the input register operand both need to
be reloaded using a register in class R1_REGS when generating 64-bit code.
This fails because there's only a single register in the class. Instead, use a
memory clobber. This also makes the __ldcw macro a compiler memory barrier.

On arm64 the TTBR0_EL1 register is set to either the reserved TTBR0
page tables on boot or to the active_mm mappings belonging to user space
processes, it must never be set to swapper_pg_dir page tables mappings.
When a CPU is booted its active_mm is set to init_mm even though its
TTBR0_EL1 points at the reserved TTBR0 page mappings. This implies
that when __cpu_suspend is triggered the active_mm can point at
init_mm even if the current TTBR0_EL1 register contains the reserved
TTBR0_EL1 mappings.
Therefore, the mm save and restore executed in __cpu_suspend might
turn out to be erroneous in that, if the current->active_mm corresponds
to init_mm, on resume from low power it ends up restoring in the
TTBR0_EL1 the init_mm mappings that are global and can cause speculation
of TLB entries which end up being propagated to user space.
This patch fixes the issue by checking the active_mm pointer before
restoring the TTBR0 mappings. If the current active_mm == &init_mm,
the code sets the TTBR0_EL1 to the reserved TTBR0 mapping instead of
switching back to the active_mm, which is the expected behaviour
corresponding to the TTBR0_EL1 settings when __cpu_suspend was entered.
