We get a NULL pointer dereference on omap3 for thumb2 compiled kernels:

The power management related assembly on omaps needs to interact with
ARM mode bootrom code, so we need to keep most of the related assembly
in ARM mode.
Turns out this error is because of missing ENDPROC for assembly code
as suggested by Stephen Boyd <sboyd@codeaurora.org>. Let's fix the
problem by adding ENDPROC in two places to sleep34xx.S.
Let's also remove the now duplicate custom code for mode switching.
This has been unnecessary since commit 6ebbf2ce437b ("ARM: convert
all "mov.* pc, reg" to "bx reg" for ARMv6+").
And let's also remove the comments about local variables, they are
now just confusing after the ENDPROC.
The reason why ENDPROC makes a difference is it sets .type and then
the compiler knows what to do with the thumb bit as explained at:

Commit 97badf873ab6 (device property: Make it possible to use
secondary firmware nodes) uncovered a bug in the x86 (and ia64) PCI
host bridge initialization code that assumes bridge->bus->sysdata
to always point to a struct pci_sysdata object which need not be
the case (in particular, the Xen PCI frontend driver sets it to point
to a different data type). If it is not the case, an incorrect
pointer (or a piece of data that is not a pointer at all) will be
passed to ACPI_COMPANION_SET() and that may cause interesting
breakage to happen going forward.
To work around this problem use the observation that the ACPI
host bridge initialization always passes NULL as parent to
pci_create_root_bus(), so if pcibios_root_bridge_prepare() sees
a non-NULL parent of the bridge, it should not attempt to set
an ACPI companion for it, because that means that
pci_create_root_bus() has been called by someone else.

If the devicetree is too old and does not provide the regulator and clocks
for the power domain, we need to avoid registering the power domain.
Otherwise runtime PM will try to control the domain, which will lead to
machine hangs without the proper DT configuration data.
This restores functionality to the kernel 4.0 level if an old DT is
detected, where the power domain is constantly powered on.

I stumbled upon an AMD box that had the BIOS using a hardware performance
counter. Instead of printing out a warning and continuing, it failed and
blocked further perf counter usage.
Looking through the history, I found this commit:
a5ebe0ba3dff ("perf/x86: Check all MSRs before passing hw check")
which tweaked the rules for a Xen guest on an almost identical box and now
changed the behaviour.
Unfortunately the rules were tweaked incorrectly and will always lead to
MSR failures even though the MSRs are completely fine.
What happens now is in arch/x86/kernel/cpu/perf_event.c::check_hw_exists():
<snip>
for (i = 0; i < x86_pmu.num_counters; i++) {
reg = x86_pmu_config_addr(i);
ret = rdmsrl_safe(reg, &val);
if (ret)
goto msr_fail;
if (val & ARCH_PERFMON_EVENTSEL_ENABLE) {
bios_fail = 1;
val_fail = val;
reg_fail = reg;
}
}
<snip>
/*
* Read the current value, change it and read it back to see if it
* matches, this is needed to detect certain hardware emulators
* (qemu/kvm) that don't trap on the MSR access and always return 0s.
*/
reg = x86_pmu_event_addr(0);
^^^^
if the first perf counter is enabled, then this routine will always fail
because the counter is running. :-(
if (rdmsrl_safe(reg, &val))
goto msr_fail;
val ^= 0xffffUL;
ret = wrmsrl_safe(reg, val);
ret |= rdmsrl_safe(reg, &val_new);
if (ret || val != val_new)
goto msr_fail;
The above bios_fail used to be a 'goto' which is why it worked in the past.
Further, most vendors have migrated to using fixed counters to hide their
evilness hence this problem rarely shows up now days except on a few old boxes.
I fixed my problem and kept the spirit of the original Xen fix, by recording a
safe non-enable register to be used safely for the reading/writing check.
Because it is not enabled, this passes on bare metal boxes (like metal), but
should continue to throw an msr_fail on Xen guests because the register isn't
emulated yet.
Now I get a proper bios_fail error message and Xen should still see their
msr_fail message (untested).

Currently, pt_buffer_reset_markers() is a difficult to read knot of
arithmetics with a redundant check for multiple-entry TOPA capability,
a commented out wakeup marker placement and a logical error wrt to
stop marker placement. The latter happens when write head is not page
aligned and results in stop marker being placed one page earlier than
it actually should.
All these problems only affect PT implementations that support
multiple-entry TOPA tables (read: proper scatter-gather).
For single-entry TOPA implementations, there is no functional impact.
This patch deals with all of the above. Tested on both single-entry
and multiple-entry TOPA PT implementations.

The (SNB/IVB/HSW) HT bug only affects events that can be programmed
onto GP counters, therefore we should only limit the number of GP
counters that can be used per cpu -- iow we should not constrain the
FP counters.
Furthermore, we should only enfore such a limit when there are in fact
exclusive events being scheduled on either sibling.

The GPC rewrite to IRQ domains has been on the premise that it may break
suspend/resume for new kernels on old DT, but otherwise keep things working
from a user perspective. This was an accepted compromise to be able to move
the GIC cleanup forward.
What actually happened was that booting a new kernel on an old DT crashes
before even the console is up, so the user does not even see the warning
that the DT is too old. The warning message suggests that this has been
known before, which is clearly unacceptable.
Fix the early crash by mapping the GPC memory space if the IRQ controller
doesn't claim it. This keeps at least CPUidle and the needed CPU wakeup
workarounds working. With this fixed the system is able to boot up
properly minus the expected suspend/resume breakage.

Commit 43b4578071c0 ("perf/x86: Reduce stack usage of
x86_schedule_events()") violated the rule that 'fake' scheduling; as
used for event/group validation; should not change the event state.
This went mostly un-noticed because repeated calls of
x86_pmu::get_event_constraints() would give the same result. And
x86_pmu::put_event_constraints() would mostly not do anything.
Commit e979121b1b15 ("perf/x86/intel: Implement cross-HT corruption
bug workaround") made the situation much worse by actually setting the
event->hw.constraint value to NULL, so when validation and actual
scheduling interact we get NULL ptr derefs.
Fix it by removing the constraint pointer from the event and move it
back to an array, this time in cpuc instead of on the stack.
validate_group()
x86_schedule_events()
event->hw.constraint = c; # store
<context switch>
perf_task_event_sched_in()
...
x86_schedule_events();
event->hw.constraint = c2; # store
...
put_event_constraints(event); # assume failure to schedule
intel_put_event_constraints()
event->hw.constraint = NULL;
<context switch end>
c = event->hw.constraint; # read -> NULL
if (!test_bit(hwc->idx, c->idxmsk)) # <- *BOOM* NULL deref
This in particular is possible when the event in question is a
cpu-wide event and group-leader, where the validate_group() tries to
add an event to the group.

The srm console is always built in. It will never be modular,
so using module_init as an alias for __initcall is rather
misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Direct use of __initcall is discouraged, vs prioritized ones.
Use of device_initcall is consistent with what __initcall
maps onto, and hence does not change the init order, making the
impact of this change zero. Should someone with real hardware
for boot testing want to change it later to arch_initcall or
console_initcall, they can do that at a later date.

x86 has variable length encoding. x86 JIT compiler is trying
to pick the shortest encoding for given bpf instruction.
While doing so the jump targets are changing, so JIT is doing
multiple passes over the program. Typical program needs 3 passes.
Some very short programs converge with 2 passes. Large programs
may need 4 or 5. But specially crafted bpf programs may hit the
pass limit and if the program converges on the last iteration
the JIT compiler will be producing an image full of 'int 3' insns.
Fix this corner case by doing final iteration over bpf program.

bpf_tail_call() arguments:
ctx - context pointer
jmp_table - one of BPF_MAP_TYPE_PROG_ARRAY maps used as the jump table
index - index in the jump table
In this implementation x64 JIT bypasses stack unwind and jumps into the
callee program after prologue, so the callee program reuses the same stack.
The logic can be roughly expressed in C like:
u32 tail_call_cnt;
void *jumptable[2] = { &&label1, &&label2 };
int bpf_prog1(void *ctx)
{
label1:
...
}
int bpf_prog2(void *ctx)
{
label2:
...
}
int bpf_prog1(void *ctx)
{
...
if (tail_call_cnt++ < MAX_TAIL_CALL_CNT)
goto *jumptable[index]; ... and pass my 'ctx' to callee ...
... fall through if no entry in jumptable ...
}
Note that 'skip current program epilogue and next program prologue' is
an optimization. Other JITs don't have to do it the same way.
>From safety point of view it's valid as well, since programs always
initialize the stack before use, so any residue in the stack left by
the current program is not going be read. The same verifier checks are
done for the calls from the kernel into all bpf programs.

While Sitara AM335x SoCs are very close to OMAP SoCs, the 32-line GPIO
controllers are numbered from 0 on AM335x and from 1 on OMAP. But when
the configuration for the TI WLAN controllers was converted from
platform data to device tree, this detail was overlooked, as 10 boards
were using OMAP with the WL12xx and WL18xx controllers, and only one
was based on AM335x.
This invalid configuration prevents the WL1271 module on the AM335x
EVM-SK from notifying interrupts to the SoC, and breaks the wlan driver.
The DTS must be corrected to use the correct GPIO controller.

The kernel's handling of 'compacted' xsave state layout is buggy:
http://marc.info/?l=linux-kernel&m=142967852317199
I don't have such a system, and the description there is vague, but
from extrapolation I guess that there were two kinds of bugs
observed:
- boot crashes, due to size calculations being wrong and the dynamic
allocation allocating a too small xstate area. (This is now fixed
in the new FPU code - but still present in stable kernels.)
- FPU state corruption and ABI breakage: if signal handlers try to
change the FPU state in standard format, which then the kernel
tries to restore in the compacted format.
These breakages are scary, but they only occur on a small number of
systems that have XSAVES* CPU support. Yet we have had XSAVES support
in the upstream kernel for a large number of stable kernel releases,
and the fixes are involved and unproven.
So do the safe resolution first: disable XSAVES* support and only
use the standard xstate format. This makes the code work and is
easy to backport.
On top of this we can work on enabling (and testing!) proper
compacted format support, without backporting pressure, on top of the
new, cleaned up FPU code.

Commit 338d9dd3e2ae ("ARM: 8351/1: perf: don't warn about missing

we avoid parsing the interrupt-affinity property for these naturally
affine interrupts.
Unfortunately, this check can trigger an early (successful) return and
we will leak the irqs array. This patch fixes the issue by reordering
the code so that the check is performed before any independent
allocation.
