The cpu_has_local_ebase macro is, confusingly, not used to indicate
whether the EBase register is local to a CPU or not. Instead it
indicates whether we want to generate the TLB refill exception vector
each time a CPU is brought online. Doing this makes little sense on any
system, since we always use the same value for EBase & thus we cannot
have different TLB refill exception handlers per CPU.
Regenerating the code is not only pointless but also can be actively
harmful, as commit 8759934e2b ("MIPS: Build uasm-generated code only
once to avoid CPU Hotplug problem") described. That commit introduced
cpu_has_local_ebase to disable the handler regeneration for Loongson
machines, but this is by no means a Loongson-specific problem.
Remove cpu_has_local_ebase & simply generate the TLB refill handler once
during boot, just like the rest of the TLB exception handlers.

We already know whether a CPU has r3k style exceptions, including TLB
exceptions, by checking cpu_has_3kex. Remove the list of CPU types in
build_tlb_refill_handler() & check cpu_has_3kex instead.

Currently areas where we need to determine whether the TLB is R3k-style
need to check for either of CONFIG_CPU_R3000 || CONFIG_CPU_TX39XX.
Introduce a new CONFIG_CPU_R3K_TLB & select it from both of the above,
allowing us to simplify checks for R3k-style TLBs by only checking for
this new Kconfig option.

This is because cpuidle_add_sysfs() will return with -ENODEV as a
consequence from get_cpu_device() return no device for a non-existing
CPU.
Instead switch to cpuidle_register_driver() and manually register each
of the present cpus through cpuhp_setup_state() callbacks and future
ones that get onlined or offlined. This mimmics similar logic that
intel_idle does.

SD_BALANCE_{FORK,EXEC} and SD_WAKE_AFFINE are stripped in sd_init()
for any sched domains with a NUMA distance greater than 2 hops
(RECLAIM_DISTANCE). The idea being that it's expensive to balance
across domains that far apart.
However, as is rather unfortunately explained in:
commit 32e45ff43e ("mm: increase RECLAIM_DISTANCE to 30")
the value for RECLAIM_DISTANCE is based on node distance tables from
2011-era hardware.
Current AMD EPYC machines have the following NUMA node distances:
node distances:
node 0 1 2 3 4 5 6 7
0: 10 16 16 16 32 32 32 32
1: 16 10 16 16 32 32 32 32
2: 16 16 10 16 32 32 32 32
3: 16 16 16 10 32 32 32 32
4: 32 32 32 32 10 16 16 16
5: 32 32 32 32 16 10 16 16
6: 32 32 32 32 16 16 10 16
7: 32 32 32 32 16 16 16 10
where 2 hops is 32.
The result is that the scheduler fails to load balance properly across
NUMA nodes on different sockets -- 2 hops apart.
For example, pinning 16 busy threads to NUMA nodes 0 (CPUs 0-7) and 4
(CPUs 32-39) like so,
$ numactl -C 0-7,32-39 ./spinner 16
causes all threads to fork and remain on node 0 until the active
balancer kicks in after a few seconds and forcibly moves some threads
to node 4.
Override node_reclaim_distance for AMD Zen.

Commit aff138bf8e ("ARM: dts: exynos: Add TMU nodes regulator supply
for Peach boards") assigned LDO10 to Exynos Thermal Measurement Unit,
but it turned out that it supplies also some other critical parts and
board freezes/crashes when it is turned off.
The mentioned commit made Exynos TMU a consumer of that regulator and in
typical case Exynos TMU driver keeps it enabled from early boot. However
there are such configurations (example is multi_v7_defconfig), in which
some of the regulators are compiled as modules and are not available
from early boot. In such case it may happen that LDO10 is turned off by
regulator core, because it has no consumers yet (in this case consumer
drivers cannot get it, because the supply regulators for it are not yet
available). This in turn causes the board to crash. This patch restores
'always-on' property for the LDO10 regulator.

Commit
a90118c445 ("x86/boot: Save fields explicitly, zero out everything else")
now zeroes the secure boot setting information (enabled/disabled/...)
passed by the boot loader or by the kernel's EFI handover mechanism.
The problem manifests itself with signed kernels using the EFI handoff
protocol with grub and the kernel loses the information whether secure
boot is enabled in the firmware, i.e., the log message "Secure boot
enabled" becomes "Secure boot could not be determined".
efi_main() arch/x86/boot/compressed/eboot.c sets this field early but it
is subsequently zeroed by the above referenced commit.
Include boot_params.secure_boot in the preserve field list.

Provide a Kconfig choice to select whether only the default ABI, only
call0 ABI or both are supported. The default for XEA2 is windowed, but
it may change for XEA3. Call0 only runs userspace with PS.WOE disabled.
Supporting both windowed and call0 ABIs is tricky, as there's no
indication in the ELF binaries which ABI they use. So it is done by
probing: each process is started with PS.WOE disabled, but the handler
of an illegal instruction exception taken with PS.WOE retries faulting
instruction after enabling PS.WOE. It must happen before any signal is
delivered to the process, otherwise it may be delivered incorrectly.

Pull x86 fixes from Thomas Gleixner:
"A set of fixes for x86:
- Fix the bogus detection of 32bit user mode for uretprobes which
caused corruption of the user return address resulting in
application crashes. In the uprobes handler in_ia32_syscall() is
obviously always returning false on a 64bit kernel. Use
user_64bit_mode() instead which works correctly.
- Prevent large page splitting when ftrace flips RW/RO on the kernel
text which caused iTLB performance issues. Ftrace wants to be
converted to text_poke() which avoids the problem, but for now
allow large page preservation in the static protections check when
the change request spawns a full large page.
- Prevent arch_dynirq_lower_bound() from returning 0 when the IOAPIC
is configured via device tree. In the device tree case the GSI 1:1
mapping is meaningless therefore the lower bound which protects the
GSI range on ACPI machines is irrelevant. Return the lower bound
which the core hands to the function instead of blindly returning 0
which causes the core to allocate the invalid virtual interupt
number 0 which in turn prevents all drivers from allocating and
requesting an interrupt.
- Remove the bogus initialization of LDR and DFR in the 32bit bigsmp
APIC driver. That uses physical destination mode where LDR/DFR are
ignored, but the initialization and the missing clear of LDR caused
the APIC to be left in a inconsistent state on kexec/reboot.
- Clear LDR when clearing the APIC registers so the APIC is in a well
defined state.
- Initialize variables proper in the find_trampoline_placement()
code.
- Silence GCC( build warning for the real mode part of the build"
