Pull Kbuild fixes from Masahiro Yamada:

- fix __uint128_t capability test in Kconfig when GCC that defaults to
32-bit is used to build the 64-bit kernel

- suppress new noisy Clang warnings -Wpointer-to-enum-cast

- move the namespace field in Module.symvers for the backward
compatibility reason for the depmod tool

- use available compression for initramdisk when INTRAMFS_SOURCE is
defined, which was the original behavior

- fix modpost to handle correct large section numbers when it refers to
modversion CRCs and module namespaces

- fix comments and documents

scripts/kallsyms: fix wrong kallsyms_relative_base

scripts/kallsyms: fix wrong kallsyms_relative_base

There is the code in the read_symbol function in 'scripts/kallsyms.c':

if (is_ignored_symbol(name, type))
return NULL;

/* Ignore most absolute/undefined (?) symbols. */
if (strcmp(name, "_text") == 0)
_text = addr;

But the is_ignored_symbol function returns true for name="_text" and
type='A'. So the next condition is not executed and the _text variable
is always zero.

It makes the wrong kallsyms_relative_base symbol as a result of the code
(CONFIG_KALLSYMS_BASE_RELATIVE is defined):

if (base_relative) {
output_label("kallsyms_relative_base");
output_address(relative_base);
printf("\n");
}

Because the output_address function uses the _text variable.

So the kallsyms_lookup function and all related functions in the kernel
do not work properly. For example, the stack trace in oops:

Call Trace:
[aa095e58] [809feab8] kobj_ns_ops_tbl+0x7ff09ac8/0x7ff1c1c4 (unreliable)
[aa095e98] [80002b64] kobj_ns_ops_tbl+0x7f50db74/0x80000010

[aa095f38] [8000f238] kobj_ns_ops_tbl+0x7f51a248/0x80000010

The right stack trace:

Call Trace:

KVM: s390: Features and Enhancements for 5.7 part1

1. Allow to disable gisa
2. protected virtual machines
Protected VMs (PVM) are KVM VMs, where KVM can't access the VM's
state like guest memory and guest registers anymore. Instead the
PVMs are mostly managed by a new entity called Ultravisor (UV),
which provides an API, so KVM and the PV can request management
actions.

PVMs are encrypted at rest and protected from hypervisor access
while running. They switch from a normal operation into protected
mode, so we can still use the standard boot process to load a
encrypted blob and then move it into protected mode.

Rebooting is only possible by passing through the unprotected/normal
mode and switching to protected again.

One mm related patch will go via Andrews mm tree ( mm/gup/writeback:
add callbacks for inaccessible pages)

Merge series "Compatible string consolidation for NXP DSPI driver" from Vladimir Oltean <olteanv@gmail.com>:

This series makes room in the driver for differentiation between the
controllers which currently operate in TCFQ mode. Most of these are
actually capable of a lot more in terms of throughput. This is in
preparation of a second series which will convert the remaining users of
TCFQ mode altogether to XSPI mode with command cycling.
