The ret value might be -EBUSY, caller will think lru lock is still
locked but actually NOT. So return -ENOSPC instead. Otherwise we hit
list corruption.

ttm_bo_cleanup_refs might fail too if BO is not idle. If we return 0,
caller(ttm_tt_populate -> ttm_global_swapout ->ttm_device_swapout) will
be stuck as we actually did not free any BO memory. This usually happens
when the fence is not signaled for a long time.

Remove CONFIG_SET_FS from parisc, so we need to add
__get_kernel_nofault() and __put_kernel_nofault(), define
HAVE_GET_KERNEL_NOFAULT and remove set_fs(), get_fs(), load_sr2(),
thread_info->addr_limit, KERNEL_DS and USER_DS.

The nice side-effect of this patch is that we now can directly access
userspace via sr3 without the need to use a temporary sr2 which is
either copied from sr3 or set to zero (for kernel space).

KVM in nVHE mode divides up its VA space into two equal halves, and
picks the half that does not conflict with the HYP ID map to map its
linear region. This worked fine when the kernel's linear map itself was
guaranteed to cover precisely as many bits of VA space, but this was
changed by commit f4693c27 ("arm64: mm: extend linear region for
52-bit VA configurations").

The result is that, depending on the placement of the ID map, kernel-VA
to hyp-VA translations may produce addresses that either conflict with
other HYP mappings (including the ID map itself) or generate addresses
outside of the 52-bit addressable range, neither of which is likely to
lead to anything useful.

Given that 52-bit capable cores are guaranteed to implement VHE, this
only affects configurations such as pKVM where we opt into non-VHE mode
even if the hardware is VHE capable. So just for these configurations,
let's limit the kernel linear map to 51 bits and work around the
problem.

adc_tm5_register_tzd() registers the thermal zone sensors for all
channels of the thermal monitor. If the registration of one channel
fails the function skips the processing of the remaining channels
and returns an error, which results in _probe() being aborted.

One of the reasons the registration could fail is that none of the
thermal zones is using the channel/sensor, which hardly is a critical
error (if it is an error at all). If this case is detected emit a
warning and continue with processing the remaining channels.

Although strictly it is the AMD and Intel drivers which have an existing
expectation of lazy behaviour by default, it ends up being rather
unintuitive to describe this literally in Kconfig. Express it instead as
an architecture dependency, to clarify that it is a valid config-time
decision. The end result is the same since virtio-iommu doesn't support
lazy mode and thus falls back to strict at runtime regardless.

The per-architecture disparity is a matter of historical expectations:
the AMD and Intel drivers have been lazy by default since 2008, and
changing that gets noticed by people asking where their I/O throughput
has gone. Conversely, Arm-based systems with their wider assortment of
IOMMU drivers mostly only support strict mode anyway; only the Arm SMMU
drivers have later grown support for passthrough and lazy mode, for
users who wanted to explicitly trade off isolation for performance.
These days, reducing the default level of isolation in a way which may
go unnoticed by users who expect otherwise hardly seems worth risking
for the sake of one line of Kconfig, so here's where we are.
