The error reporting from the insn_fetch_from_user*() functions is not
very verbose. Extend it to include information on whether the linear
RIP could not be calculated or whether the memory access faulted.

This will be used in the SEV-ES code to propagate the correct
exception depending on what went wrong during instruction fetch.

When an instruction is fetched from user-space, segmentation needs to
be taken into account. This means that getting the linear address of an
instruction can fail. Hardware would raise a #GP exception in that case,
but the #VC exception handler would emulate it as a page-fault.

The insn_fetch_from_user*() functions now provide the relevant
information in case of a failure. Use that and propagate a #GP when the
linear address of an instruction to fetch could not be calculated.

Userspace support has no dependency on the toolchain therefore all
toolchain checks and build flags are controlled the new config

If the kernel is not compiled with CONFIG_ARM64_PTR_AUTH_KERNEL=y,
then no PACI/AUTI instructions are expected while the kernel is running
so the kernel's key will not be used. Write of a system registers
is expensive therefore avoid if not required.

SECTION_[SHIFT|SIZE|MASK] are essentially PMD_[SHIFT|SIZE|MASK]. But these
create confusion being similar to generic sparsemem memory sections, which
are derived from SECTION_SIZE_BITS. Section references have always implied
PMD level block mapping. Instead just use all PMD level macros which would
make it explicit and also remove confusion with sparsmem memory sections.

Currently, the lower bits of fault address is cleared before it's
passed to handle_mm_fault(). It's unnecessary since generic code
does same thing since the commit 1a29d85 ("mm: use vmf->address
instead of of vmf->virtual_address").

This passes the original fault address to handle_mm_fault() in case
the generic code needs to know the exact fault address.

Intel client processors that support the IA32_TSX_FORCE_ABORT MSR
related to perf counter interaction [1] received a microcode update that
deprecates the Transactional Synchronization Extension (TSX) feature.
The bit FORCE_ABORT_RTM now defaults to 1, writes to this bit are
ignored. A new bit TSX_CPUID_CLEAR clears the TSX related CPUID bits.

The summary of changes to the IA32_TSX_FORCE_ABORT MSR are:

  Bit 0: FORCE_ABORT_RTM (legacy bit, new default=1) Status bit that
  indicates if RTM transactions are always aborted. This bit is
  essentially !SDV_ENABLE_RTM(Bit 2). Writes to this bit are ignored.

  Bit 1: TSX_CPUID_CLEAR (new bit, default=0) When set, CPUID.HLE = 0
  and CPUID.RTM = 0.

  Bit 2: SDV_ENABLE_RTM (new bit, default=0) When clear, XBEGIN will
  always abort with EAX code 0. When set, XBEGIN will not be forced to
  abort (but will always abort in SGX enclaves). This bit is intended to
  be used on developer systems. If this bit is set, transactional
  atomicity correctness is not certain. SDV = Software Development
  Vehicle (SDV), i.e. developer systems.

Performance monitoring counter 3 is usable in all cases, regardless of
the value of above bits.

Add support for a new CPUID bit - CPUID.RTM_ALWAYS_ABORT (CPUID 7.EDX[11])
 - to indicate the status of always abort behavior.

As a result of TSX deprecation, some processors always abort TSX
transactions by default after a microcode update.

When TSX feature cannot be used it is better to hide it. Clear CPUID.RTM
and CPUID.HLE bits when TSX transactions always abort.

When using CONFIG_ARM64_SW_TTBR0_PAN, a task's thread_info::ttbr0 must be
the TTBR0_EL1 value used to run userspace. With 52-bit PAs, the PA must be
packed into the TTBR using phys_to_ttbr(), but we forget to do this in some
of the SW PAN code. Thus, if the value is installed into TTBR0_EL1 (as may
happen in the uaccess routines), this could result in UNPREDICTABLE
behaviour.

Since hardware with 52-bit PA support almost certainly has HW PAN, which
will be used in preference, this shouldn't be a practical issue, but let's
fix this for consistency.

The BPA-RS600 doesn't follow the PMBus spec for linear data.
Specifically it treats the mantissa as an unsigned 11-bit value instead
of a two's complement 11-bit value. At this point it's unclear whether
this only affects Vin or if Pin/Pout1 are affected as well. Erring on
the side of caution only Vin is dealt with here.

Support set_trips() callback of thermal device ops. This allows HWMON
device to operatively notify thermal core about temperature changes, which
is very handy to have in a case where HWMON sensor is used by CPU thermal
zone that performs passive cooling and emergency shutdown on overheat.
Thermal core will be able to react faster to temperature changes.

The set_trips() callback is entirely optional. If HWMON sensor doesn't
support setting thermal trips, then the callback is a NO-OP. The dummy
callback has no effect on the thermal core. The temperature trips are
either complement the temperature polling mechanism of thermal core or
replace the polling if sensor can set the trips and polling is disabled
by a particular device in a device-tree.

	This made it into 5.13 final, and completely breaks NFSD for me
	(Serving tcp v3 mounts).  Existing mounts on clients hang, as do
	new mounts from new clients.  Rebooting the server back to rc7
	everything recovers.

The commit b3b64eb ("mm/page_alloc: do bulk array bounds check after

already populated which is interpreted as an allocation failure. Dave

 "The big change in this round is that we're finally in a position where
  we can sanely remove the old drivers/ide/ code, as libata covers
  everything we need by now.

  This is exciting for two reasons:

   1) we delete a lot of legacy code that doesn't really meet the
      standards we have today, and

   2) it enables us to clean up various bits in the block layer that
      exist only because of the old IDE code.

  Outside of that, just a few minor fixes here, fixups for warnings,
  etc"

       Much reduction in complexity from that series:

           63 files changed, 756 insertions(+), 4094 deletions(-)

 - Futexes:

       set FLAGS_CLOCKRT (.e. uses CLOCK_MONOTONIC).

         FLAGS_CLOCKRT & invert the flag's meaning to avoid having to
         introduce a new variant was resisted successfully. ]

Pull scheduler udpates from Ingo Molnar:

 - Changes to core scheduling facilities:

    - Add "Core Scheduling" via CONFIG_SCHED_CORE=y, which enables
      coordinated scheduling across SMT siblings. This is a much
      requested feature for cloud computing platforms, to allow the
      flexible utilization of SMT siblings, without exposing untrusted
      domains to information leaks & side channels, plus to ensure more
      deterministic computing performance on SMT systems used by
      heterogenous workloads.

      There are new prctls to set core scheduling groups, which allows
      more flexible management of workloads that can share siblings.

    - Fix task->state access anti-patterns that may result in missed
      wakeups and rename it to ->__state in the process to catch new
      abuses.

 - Load-balancing changes:

    - Tweak newidle_balance for fair-sched, to improve 'memcache'-like
      workloads.

    - "Age" (decay) average idle time, to better track & improve
      workloads such as 'tbench'.

    - Fix & improve energy-aware (EAS) balancing logic & metrics.

    - Fix & improve the uclamp metrics.

    - Fix task migration (taskset) corner case on !CONFIG_CPUSET.

    - Fix RT and deadline utilization tracking across policy changes

    - Introduce a "burstable" CFS controller via cgroups, which allows
      bursty CPU-bound workloads to borrow a bit against their future
      quota to improve overall latencies & batching. Can be tweaked via
      /sys/fs/cgroup/cpu/<X>/cpu.cfs_burst_us.

    - Rework assymetric topology/capacity detection & handling.

 - Scheduler statistics & tooling:

    - Disable delayacct by default, but add a sysctl to enable it at
      runtime if tooling needs it. Use static keys and other
      optimizations to make it more palatable.

    - Use sched_clock() in delayacct, instead of ktime_get_ns().

Pull x86 splitlock updates from Ingo Molnar:

 - Add the "ratelimit:N" parameter to the split_lock_detect= boot
   option, to rate-limit the generation of bus-lock exceptions.

   This is both easier on system resources and kinder to offending
   applications than the current policy of outright killing them.

 - Document the split-lock detection feature and its parameters.

Pull arm64 updates from Will Deacon:
 "There's a reasonable amount here and the juicy details are all below.

  It's worth noting that the MTE/KASAN changes strayed outside of our
  usual directories due to core mm changes and some associated changes
  to some other architectures; Andrew asked for us to carry these [1]
  rather that take them via the -mm tree.

  Summary:

   - Optimise SVE switching for CPUs with 128-bit implementations.

   - Fix output format from SVE selftest.

   - Add support for versions v1.2 and 1.3 of the SMC calling
     convention.

   - Allow Pointer Authentication to be configured independently for
     kernel and userspace.

   - PMU driver cleanups for managing IRQ affinity and exposing event
     attributes via sysfs.

   - KASAN optimisations for both hardware tagging (MTE) and out-of-line
     software tagging implementations.

   - Relax frame record alignment requirements to facilitate 8-byte
     alignment with KASAN and Clang.

   - Cleanup of page-table definitions and removal of unused memory
     types.

   - Reduction of ARCH_DMA_MINALIGN back to 64 bytes.

   - Refactoring of our instruction decoding routines and addition of
     some missing encodings.

   - Move entry code moved into C and hardened against harmful compiler
     instrumentation.

   - Update booting requirements for the FEAT_HCX feature, added to v8.7
     of the architecture.

   - Fix resume from idle when pNMI is being used.

   - Additional CPU sanity checks for MTE and preparatory changes for
     systems where not all of the CPUs support 32-bit EL0.

   - Update our kernel string routines to the latest Cortex Strings
     implementation.

   - Big cleanup of our cache maintenance routines, which were
     confusingly named and inconsistent in their implementations.

   - Tweak linker flags so that GDB can understand vmlinux when using
     RELR relocations.

   - Boot path cleanups to enable early initialisation of per-cpu
     operations needed by KCSAN.

   - Non-critical fixes and miscellaneous cleanup"
