CONFIG_LOCKUP_DETECTOR was split into two separate config options,
CONFIG_HARDLOCKUP_DETECTOR and CONFIG_SOFTLOCKUP_DETECTOR.
Our defconfigs still have CONFIG_LOCKUP_DETECTOR=y, but that is no longer
user selectable, and we don't mention the new options, so we end up with
none of them enabled.
So update the defconfigs to turn on the new SOFT and HARD options, the

Highlights include:
- Larger virtual address space on 64-bit server CPUs. By default we use a 128TB
virtual address space, but a process can request access to the full 512TB by
passing a hint to mmap().
- Support for the new Power9 "XIVE" interrupt controller.
- TLB flushing optimisations for the radix MMU on Power9.
- Support for CAPI cards on Power9, using the "Coherent Accelerator Interface
Architecture 2.0".
- The ability to configure the mmap randomisation limits at build and runtime.
- Several small fixes and cleanups to the kprobes code, as well as support for
KPROBES_ON_FTRACE.
- Major improvements to handling of system reset interrupts, correctly treating
them as NMIs, giving them a dedicated stack and using a new hypervisor call
to trigger them, all of which should aid debugging and robustness.
Many fixes and other minor enhancements.

This reverts commit ec99907244 ("powerpc/pseries: Auto-online
hotplugged memory"), and 9dc512819e ("powerpc: Fix unused function
warning 'lmb_to_memblock'").
Using the auto-online acpability does online added memory but does not
update the associated device struct to indicate that the memory is
online. This causes the pseries memory DLPAR code to fail when trying to
remove a LMB that was previously removed and added back. This happens
when validating that the LMB is removable.
This patch reverts to the previous behavior of calling device_online()
to online the LMB when it is DLPAR added and moves the lmb_to_memblock()
routine out of CONFIG_MEMORY_HOTREMOVE now that we call it for add.
Fixes: ec99907244 ("powerpc/pseries: Auto-online hotplugged memory")

These are common on bare metal machines, so put them in the defconfig.

This doesn't have any benefit apart from saving a small amount of memory
when it is disabled. The ifdef hackery in the code makes it dirty
unnecessarily.
Clean it up by removing the Kconfig option completely. Few defconfigs
are also updated and CONFIG_CPU_FREQ_STAT_DETAILS is replaced with
CONFIG_CPU_FREQ_STAT now in them, as users wanted stats to be enabled.

Highlights include:
- Support for the kexec_file_load() syscall, which is a prereq for secure and
trusted boot.
- Prevent kernel execution of userspace on P9 Radix (similar to SMEP/PXN).
- Sort the exception tables at build time, to save time at boot, and store
them as relative offsets to save space in the kernel image & memory.
- Allow building the kernel with thin archives, which should allow us to build
an allyesconfig once some other fixes land.
- Build fixes to allow us to correctly rebuild when changing the kernel endian
from big to little or vice versa.
- Plumbing so that we can avoid doing a full mm TLB flush on P9 Radix.
- Initial stack protector support (-fstack-protector).
- Support for dumping the radix (aka. Linux) and hash page tables via debugfs.
- Fix an oops in cxl coredump generation when cxl_get_fd() is used.
- Freescale updates from Scott: "Highlights include 8xx hugepage support,
qbman fixes/cleanup, device tree updates, and some misc cleanup."
- Many and varied fixes and minor enhancements as always.
