This patch set contains an assortment of RISC-V related patches that I'd
like to target for the 5.2 merge window. Most of the patches are
cleanups, but there are a handful of user-visible changes:
* The nosmp and nr_cpus command-line arguments are now supported, which
work like normal.
* The SBI console no longer installs itself as a preferred console, we
rely on standard mechanisms (/chosen, command-line, hueristics)
instead.
* sfence_remove_sfence_vma{,_asid} now pass their arguments along to the
SBI call.
* Modules now support BUG().
* A missing sfence.vma during boot has been added. This bug only
manifests during boot.
* The arch/riscv support for SiFive's L2 cache controller has been
merged, which should un-block the EDAC framework work.
I've only tested this on QEMU again, as I didn't have time to get things
running on the Unleashed. The latest master from this morning merges in
cleanly and passes the tests as well.
This patch set rebased my "5.2 MW, Part 1" patch set which includes an
erronous empty file. It's also a rebase of my "5.2 MW, Part 2" patch
set, in which I managed to create another file while attempting to
remove the empty file.
Sorry for all the noise!

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
("kbuild: do not drop -I without parameter").

As of Linux 5.1, alpha and s390 are the last architectures that
have defconfig in arch/*/ instead of arch/*/configs/.
$ find arch -name defconfig | sort
arch/alpha/defconfig
arch/arm64/configs/defconfig
arch/csky/configs/defconfig
arch/nds32/configs/defconfig
arch/riscv/configs/defconfig
arch/s390/defconfig
The arch/$(ARCH)/defconfig is the hard-coded default in Kconfig,
and I want to deprecate it after evacuating the remaining defconfig
into the standard location, arch/*/configs/.
Define KBUILD_DEFCONFIG like other architectures, and move defconfig
into the configs/ subdirectory.

arch/sh/boot/.gitignore has the pattern "vmlinux*"; this is effective
not only for the current directory, but also for any sub-directories.
So, from the point of .gitignore grammar, the following check-in files
are also considered to be ignored:
arch/sh/boot/compressed/vmlinux.scr
arch/sh/boot/romimage/vmlinux.scr
As the manual gitignore(5) says "Files already tracked by Git are not
affected", this is not a problem as far as Git is concerned.
However, Git is not the only program that parses .gitignore because
.gitignore is useful to distinguish build artifacts from source files.
For example, tar(1) supports the --exclude-vcs-ignore option. As of
writing, this option does not work perfectly, but it intends to create
a tarball excluding files specified by .gitignore.
So, I believe it is better to fix this issue.

Accesses by userspace to random addresses outside the user or kernel
address range will generate an SLB fault. When we handle that fault we
classify the effective address into several classes, eg. user, kernel
linear, kernel virtual etc.
For addresses that are completely outside of any valid range, we
should not insert an SLB entry at all, and instead immediately an
exception.
In the past this was handled in two ways. Firstly we would check the
top nibble of the address (using REGION_ID(ea)) and that would tell us
if the address was user (0), kernel linear (c), kernel virtual (d), or
vmemmap (f). If the address didn't match any of these it was invalid.
Then for each type of address we would do a secondary check. For the
user region we check against H_PGTABLE_RANGE, for kernel linear we
would mask the top nibble of the address and then check the address
against MAX_PHYSMEM_BITS.
As part of commit 0034d395f8 ("powerpc/mm/hash64: Map all the kernel
regions in the same 0xc range") we replaced REGION_ID() with
get_region_id() and changed the masking of the top nibble to only mask
the top two bits, which introduced a bug.
Addresses less than (4 << 60) are still handled correctly, they are
either less than (1 << 60) in which case they are subject to the
H_PGTABLE_RANGE check, or they are correctly checked against
MAX_PHYSMEM_BITS.
However addresses from (4 << 60) to ((0xc << 60) - 1), are incorrectly
treated as kernel linear addresses in get_region_id(). Then the top
two bits are cleared by EA_MASK in slb_allocate_kernel() and the
address is checked against MAX_PHYSMEM_BITS, which it passes due to
the masking. The end result is we incorrectly insert SLB entries for
those addresses.
That is not actually catastrophic, having inserted the SLB entry we
will then go on to take a page fault for the address and at that point
we detect the problem and report it as a bad fault.
Still we should not be inserting those entries, or treating them as
kernel linear addresses in the first place. So fix get_region_id() to
detect addresses in that range and return an invalid region id, which
we cause use to not insert an SLB entry and directly report an
exception.

The macro __BUG_INSN currently is defined as the "ebreak" opcode.
The is_valid_bugaddr() function compares the instruction pointed to by
$sepc with macro __BUG_INSN to check whether the current trap exception
is caused by an "ebreak" instruction. However, this check flow is possibly
erroneous because if C extension is supported, the expected trap
instruction "ebreak" is possibly translated to "c.ebreak" by the assembler.
Therefore, it requires a mechanism to distinguish the length of the
instruction in $spec and compare it to the correct trap instruction.

arm64: tegra: Device tree fixes for v5.2-rc1
This contains one patch to disable the recently added XUSB support on
Jetson TX2 which is reported to cause boot and CPU hotplug failures in
some cases and doesn't allow the core power rail to be switched off.
Furthermore there are some changes to enable IOMMU support on more
devices. This is needed in order to prevent these devices from breaking
with the policy change in the ARM SMMU driver to break insecure devices
that is currently headed for v5.2.

This enables the ARM_GIC_PM driver by default for Tegra in order to
increase build coverage.
