virt device tree incorrectly uses 0xf0000000 on both sides of PCI IO
ports address space mapping. This results in incorrect port address
assignment in PCI IO BARs and subsequent crash on attempt to access
them. Use 0 as base address in PCI IO ports address space.

The commit e7774049ff25 ("ARM: dts: bcm283x: Define MMC interfaces at
board level") accidently dropped the bus width for the sdhci on the
RPi Zero W, because the board file was relying on the defaults
from bcm2835-rpi.dtsi. So fix this performance regression by adding
the bus width to the board file.

HAVE_FAST_GUP enables the lockless quick page table walker for simple
cases, and is a nice optimization for some random loads that can then
use get_user_pages_fast() rather than the more careful page walker.
However, for some unexplained reason, it seems to be subtly broken on
sparc64. The breakage is only with some compiler versions and some
hardware, and nobody seems to have figured out what triggers it,
although there's a simple reprodicer for the problem when it does
trigger.
The problem was introduced with the conversion to the generic GUP code
in commit 7b9afb86b632 ("sparc64: use the generic get_user_pages_fast
code"), but nothing looks obviously wrong in that conversion. It may be
a compiler bug that just hits us with the code reorganization. Or it
may be something very specific to sparc64.
This disables HAVE_FAST_GUP entirely. That makes things like futexes a
bit slower, but at least they work. If we can figure out the trigger,
that would be lovely, but it's been three months already..

Check that the per-cpu cluster mask pointer has been set prior to
clearing a dying cpu's bit. The per-cpu pointer is not set until the
target cpu reaches smp_callin() during CPUHP_BRINGUP_CPU, whereas the
teardown function, x2apic_dead_cpu(), is associated with the earlier
CPUHP_X2APIC_PREPARE. If an error occurs before the cpu is awakened,
e.g. if do_boot_cpu() itself fails, x2apic_dead_cpu() will dereference
the NULL pointer and cause a panic.

Now that there's Hyper-V IOMMU driver, Linux can switch to x2apic mode
when supported by the vcpus.
However, the apic access functions for Hyper-V enlightened apic assume
xapic mode only.
As a result, Linux fails to bring up secondary cpus when run as a guest
in QEMU/KVM with both hv_apic and x2apic enabled.
According to Michael Kelley, when in x2apic mode, the Hyper-V synthetic
apic MSRs behave exactly the same as the corresponding architectural
x2apic MSRs, so there's no need to override the apic accessors. The
only exception is hv_apic_eoi_write, which benefits from lazy EOI when
available; however, its implementation works for both xapic and x2apic
modes.

Connecting a vCPU to a XIVE KVM device means establishing a 1:1
association between a vCPU id and the offset (VP id) of a VP
structure within a fixed size block of VPs. We currently try to
enforce the 1:1 relationship by checking that a vCPU with the
same id isn't already connected. This is good but unfortunately
not enough because we don't map VP ids to raw vCPU ids but to
packed vCPU ids, and the packing function kvmppc_pack_vcpu_id()
isn't bijective by design. We got away with it because QEMU passes
vCPU ids that fit well in the packing pattern. But nothing prevents
userspace to come up with a forged vCPU id resulting in a packed id
collision which causes the KVM device to associate two vCPUs to the
same VP. This greatly confuses the irq layer and ultimately crashes
the kernel, as shown below.
Example: a guest with 1 guest thread per core, a core stride of
8 and 300 vCPUs has vCPU ids 0,8,16...2392. If QEMU is patched to
inject at some point an invalid vCPU id 348, which is the packed
version of itself and 2392, we get:

If CONFIG_ARM64_SVE=n then we fail to report ID_AA64ZFR0_EL1 as 0 when
read by userspace, despite being required by the architecture. Although
this is theoretically a change in ABI, userspace will first check for
the presence of SVE via the HWCAP or the ID_AA64PFR0_EL1.SVE field
before probing the ID_AA64ZFR0_EL1 register. Given that these are
reported correctly for this configuration, we can safely tighten up the
current behaviour.
Ensure ID_AA64ZFR0_EL1 is treated as RAZ when CONFIG_ARM64_SVE=n.

__get_user_[no]check uses temporary buffer of type long to store result
of __get_user_size and do sign extension on it when necessary. This
doesn't work correctly for 64-bit data. Fix it by moving temporary
buffer/sign extension logic to __get_user_asm.
Don't do assignment of __get_user_bad result to (x) as it may not always
be integer-compatible now and issue warning even when it's going to be
optimized. Instead do (x) = 0; and call __get_user_bad separately.
Zero initialize __x in __get_user_asm and use '+' constraint for its
assembly argument, so that its value is preserved in error cases. This
may add at most 1 cycle to the fast path, but saves an instruction and
two padding bytes in the fixup section for each use of this macro and
works for both misaligned store and store exception.

Numeric assembly arguments are hard to understand and assembly code that
uses them is hard to modify. Use named arguments in __check_align_*,
__get_user_asm and __put_user_asm. Modify macro parameter names so that
they don't affect argument names. Use '+' constraint for the [err]
argument instead of having it as both input and output.

Sven noticed that calling ioremap() and iounmap() multiple times leads
to a vmap memory leak:

use vmalloc=<size> to increase size
It seems we missed calling vunmap() in iounmap().

Remove a confusing comment on our local_flush_tlb_all()
implementation. Per an internal discussion with Andrew, while it's
true that the fence.i is not necessary, it's not the case that an
sfence.vma implies a fence.i. We also drop the section about
"flush[ing] the entire local TLB" to better align with the language in
section 4.2.1 "Supervisor Memory-Management Fence Instruction" of the
RISC-V Privileged Specification v20190608.

Add a default "stdout-path" to the kernel DTS file, as is present in many
of the board DTS files elsewhere in the kernel tree. With this line
present, earlyconsole can be enabled by simply passing "earlycon" on the
kernel command line. No specific device details are necessary, since the
kernel will use the stdout-path as the default.

First of all, on short copies __copy_{to,from}_user() return the amount
of bytes left uncopied, *not* -EFAULT. get_user() and put_user() are
expected to return -EFAULT on failure.
Another problem is get_user(v32, (__u64 __user *)p); that should
fetch 64bit value and the assign it to v32, truncating it in process.
Current code, OTOH, reads 8 bytes of data and stores them at the
address of v32, stomping on the 4 bytes that follow v32 itself.

Our hardware (UV aka Superdome Flex) has address ranges marked
reserved by the BIOS. Access to these ranges is caught as an error,
causing the BIOS to halt the system.
Initial page tables mapped a large range of physical addresses that
were not checked against the list of BIOS reserved addresses, and
sometimes included reserved addresses in part of the mapped range.
Including the reserved range in the map allowed processor speculative
accesses to the reserved range, triggering a BIOS halt.
Used early in booting, the page table level2_kernel_pgt addresses 1
GiB divided into 2 MiB pages, and it was set up to linearly map a full
1 GiB of physical addresses that included the physical address range
of the kernel image, as chosen by KASLR. But this also included a
large range of unused addresses on either side of the kernel image.
And unlike the kernel image's physical address range, this extra
mapped space was not checked against the BIOS tables of usable RAM
addresses. So there were times when the addresses chosen by KASLR
would result in processor accessible mappings of BIOS reserved
physical addresses.
The kernel code did not directly access any of this extra mapped
space, but having it mapped allowed the processor to issue speculative
accesses into reserved memory, causing system halts.
This was encountered somewhat rarely on a normal system boot, and much
more often when starting the crash kernel if "crashkernel=512M,high"
was specified on the command line (this heavily restricts the physical
address of the crash kernel, in our case usually within 1 GiB of
reserved space).
The solution is to invalidate the pages of this table outside the kernel
image's space before the page table is activated. It fixes this problem
on our hardware.
