The pistachio platform uses the U-Boot bootloader & generally boots a
kernel in the uImage format. As such it's useful to build one when
building the kernel, but to do so currently requires the user to
manually specify a uImage target on the make command line.
Make uImage.gz the pistachio platform's default build target, so that
the default is to build a kernel image that we can actually boot on a
board such as the MIPS Creator Ci40.
Marked for stable backport as far as v4.1 where pistachio support was
introduced. This is primarily useful for CI systems such as kernelci.org
which will benefit from us building a suitable image which can then be
booted as part of automated testing, extending our test coverage to the
affected stable branches.

virt_addr_valid() really returns a boolean value, but currently uses an
integer to represent it. Switch to the bool type to make it clearer that
we really are returning a true or false value.

The virt_addr_valid() function is meant to return true iff
virt_to_page() will return a valid struct page reference. This is true
iff the address provided is found within the unmapped address range
between PAGE_OFFSET & MAP_BASE, but we don't currently check for that
condition. Instead we simply mask the address to obtain what will be a
physical address if the virtual address is indeed in the desired range,
shift it to form a PFN & then call pfn_valid(). This can incorrectly
return true if called with a virtual address which, after masking,
happens to form a physical address corresponding to a valid PFN.
For example we may vmalloc an address in the kernel mapped region
starting a MAP_BASE & obtain the virtual address:
addr = 0xc000000000002000
When masked by virt_to_phys(), which uses __pa() & in turn CPHYSADDR(),
we obtain the following (bogus) physical address:
addr = 0x2000
In a common system with PHYS_OFFSET=0 this will correspond to a valid
struct page which should really be accessed by virtual address
PAGE_OFFSET+0x2000, causing virt_addr_valid() to incorrectly return 1
indicating that the original address corresponds to a struct page.
This is equivalent to the ARM64 change made in commit ca219452c6
("arm64: Correctly bounds check virt_addr_valid").
This fixes fallout when hardened usercopy is enabled caused by the
related commit 517e1fbeb6 ("mm/usercopy: Drop extra
is_vmalloc_or_module() check") which removed a check for the vmalloc
range that was present from the introduction of the hardened usercopy
feature.

KVM_CAP_MAX_VCPU_ID is currently always reporting KVM_MAX_VCPU_ID on all
architectures. However, on s390x, the amount of usable CPUs is determined
during runtime - it is depending on the features of the machine the code
is running on. Since we are using the vcpu_id as an index into the SCA
structures that are defined by the hardware (see e.g. the sca_add_vcpu()
function), it is not only the amount of CPUs that is limited by the hard-
ware, but also the range of IDs that we can use.
Thus KVM_CAP_MAX_VCPU_ID must be determined during runtime on s390x, too.
So the handling of KVM_CAP_MAX_VCPU_ID has to be moved from the common
code into the architecture specific code, and on s390x we have to return
the same value here as for KVM_CAP_MAX_VCPUS.
This problem has been discovered with the kvm_create_max_vcpus selftest.
With this change applied, the selftest now passes on s390x, too.

Commit 9cc342f6c4 ("treewide: prefix header search paths with
$(srctree)/") caused a build error for MIPS VDSO.
CC arch/mips/vdso/gettimeofday.o
In file included from ../arch/mips/vdso/vdso.h:26,
from ../arch/mips/vdso/gettimeofday.c:11:
../arch/mips/include/asm/page.h:12:10: fatal error: spaces.h: No such file or directory
#include <spaces.h>
^~~~~~~~~~
The cause of the error is a missing space after the compiler flag -I .
Kbuild used to have a global restriction "no space after -I", but
commit 48f6e3cf5b ("kbuild: do not drop -I without parameter") got
rid of it. Having a space after -I is no longer a big deal as far as
Kbuild is concerned.
It is still a big deal for MIPS because arch/mips/vdso/Makefile
filters the header search paths, like this:
ccflags-vdso := \
$(filter -I%,$(KBUILD_CFLAGS)) \
..., which relies on the assumption that there is no space after -I .

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5b

had to kill off the mess we made of <asm/segment.h>, which really
shouldn't exist on most architectures"
* tag 'asm-generic-nommu' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic:
asm-generic: optimize generic uaccess for 8-byte loads and stores
asm-generic: provide entirely generic nommu uaccess
arch: mostly remove <asm/segment.h>
asm-generic: don't include <asm/segment.h> from <asm/uaccess.h>
Wire up the mount API syscalls on non-x86 arches.

This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common
place. We need to eliminate potential issues beforehand.
If it is enabled for mips, the following errors are reported:
