With the expanded support for placing the kernel in XPHYS rather than
just KSEG0, scenarios where ebase doesn't belong to KSEG0 are more
likely to occur. In such cases, we currently experience a substantial
and perplexing stack dump without any accompanying explanation. To
rectify this, we aim to replace the uninformative stack dump with a
warning that offers a clear explanation of the issue.

Now the exception vector for CPS systems are allocated on-fly
with memblock as well.

It will try to allocate from KSEG1 first, and then try to allocate
in low 4G if possible.

The main reset vector is now generated by uasm, to avoid tons
of patches to the code. Other vectors are copied to the location
later.

ebase might reside in XKPHYS if memblock is unable to allocate memory
within the KSEG0 physical range.

To map EBASE into uncached space, we convert it back to its physical
address and utilize the new CKSEG1ADDR_OR_64BIT helper for mapping.

Use GPR number macros in uasm code generation parts to
reduce code duplication.

There are functional change due to difference in register
symbolic names between OABI and NABI, while existing code
is only using definitions from OABI.

Code pieces are carefully inspected to ensure register
usages are safe on NABI as well.

We changed register allocation of r_pcohctl from T7 to T8
as T7 is not available on NABI and we just want a caller

Fix to search a field from the structure which has anonymous union
correctly.
Since the reference `type` pointer was updated in the loop, the search
loop suddenly aborted where it hits an anonymous union. Thus it can not
find the field after the anonymous union. This avoids updating the
cursor `type` pointer in the loop.

  RISC-V:

   - Fix steal-time related sparse warnings

   - Cleanup gtod_is_based_on_tsc() to return "bool" instead of an "int"

   - Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if
     and only if the incoming events->nmi.pending is non-zero. If the
     target vCPU is in the UNITIALIZED state, the spurious request will
     result in KVM exiting to userspace, which in turn causes QEMU to
     constantly acquire and release QEMU's global mutex, to the point
     where the BSP is unable to make forward progress.

   - Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl
     being incorrectly truncated, and ultimately causes KVM to think a
     fixed counter has already been disabled (KVM thinks the old value
     is '0').

   - Fix a stack leak in KVM_GET_MSRS where a failed MSR read from
     userspace that is ultimately ignored due to ignore_msrs=true
     doesn't zero the output as intended.

  Selftests cleanups and fixes:

   - Remove redundant newlines from error messages.

   - Delete an unused variable in the AMX test (which causes build
     failures when compiling with -Werror).

   - Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails
     with an error code other than ENOENT (a Hyper-V selftest bug
     resulted in an EMFILE, and the test eventually got skipped).

   - Fix TSC related bugs in several Hyper-V selftests.

   - Fix a bug in the dirty ring logging test where a sem_post() could
     be left pending across multiple runs, resulting in incorrect
     synchronization between the main thread and the vCPU worker thread.

   - Relax the dirty log split test's assertions on 4KiB mappings to fix

     for code and data that is NOT being dirty logged) changing, e.g.
     due to NUMA balancing"

   previous fix was to fix.

 - Fix tracing_on state

   The code to test if "tracing_on" is set incorrectly used
   ring_buffer_record_is_on() which returns false if the ring buffer
   isn't able to be written to.

   But the ring buffer disable has several bits that disable it. One is
   internal disabling which is used for resizing and other modifications
   of the ring buffer. But the "tracing_on" user space visible flag
   should only report if tracing is actually on and not internally
   disabled, as this can cause confusion as writing "1" when it is
   disabled will not enable it.

   Instead use ring_buffer_record_is_set_on() which shows the user space
   visible settings.

 - Fix a false positive kmemleak on saved cmdlines

   Now that the saved_cmdlines structure is allocated via alloc_page()
   and not via kmalloc() it has become invisible to kmemleak. The
   allocation done to one of its pointers was flagged as a dangling
   allocation leak. Make kmemleak aware of this allocation and free.

 - Fix synthetic event dynamic strings

   An update that cleaned up the synthetic event code removed the return
   value of trace_string(), and had it return zero instead of the
   length, causing dynamic strings in the synthetic event to always have
   zero size.
