Many devices have control registers which control some measurable
property. Often a register contains control field so that change in
this field causes linear change in the controlled property. It is not
a rare case that user wants to give 'meaningful' control values and
driver needs to convert them to register field values. Even more
often user wants to 'see' the currently set value - again in
meaningful units - and driver needs to convert the values it reads
from register to these meaningful units. Examples of this include:
- regulators, voltage/current configurations
- power, voltage/current configurations
- clk(?) NCOs
and maybe others I can't think of right now.
Provide a linear_range helper which can do conversion from user value
to register value 'selector'.
The idea here is stolen from regulator framework and patches refactoring
the regulator helpers to use this are following.
Current implementation does not support inversely proportional ranges
but it might be useful if we could support also inversely proportional
ranges?

Currently, system fails to boot because the legacy interrupt remapping
mode does not enable 128-bit IRTE (GA), which is required for x2APIC
support.
Fix by using AMD_IOMMU_GUEST_IR_LEGACY_GA mode when booting with
kernel option amd_iommu_intr=legacy instead. The initialization
logic will check GASup and automatically fallback to using
AMD_IOMMU_GUEST_IR_LEGACY if GA mode is not supported.

While working on to make io_uring sqpoll mode support syscalls that need
struct files_struct, I got cpu soft lockup in io_ring_ctx_wait_and_kill(),
while (ctx->sqo_thread && !wq_has_sleeper(&ctx->sqo_wait))
cpu_relax();
above loop never has an chance to exit, it's because preempt isn't enabled
in the kernel, and the context calling io_ring_ctx_wait_and_kill() and
io_sq_thread() run in the same cpu, if io_sq_thread calls a cond_resched()
yield cpu and another context enters above loop, then io_sq_thread() will
always in runqueue and never exit.
Use cond_resched() can fix this issue.

Fix the SELinux netlink_send hook to properly handle multiple netlink
messages in a single sk_buff; each message is parsed and subject to
SELinux access control. Prior to this patch, SELinux only inspected
the first message in the sk_buff.

On arm64 linux gcc uses -fasynchronous-unwind-tables -funwind-tables
by default since gcc-8, so now the de facto platform ABI is to allow
unwinding from async signal handlers.
However on bare metal targets (aarch64-none-elf), and on old gcc,
async and sync unwind tables are not enabled by default to avoid
runtime memory costs.
This means if linux is built with a baremetal toolchain the vdso.so
may not have unwind tables which breaks the gcc platform ABI guarantee
in userspace.
Add -fasynchronous-unwind-tables explicitly to the vgettimeofday.o
cflags to address the ABI change.

When replacing the bd_super check with a bd_openers I followed a logical
conclusion, which turns out to be utterly wrong. When a block device has
bd_super sets it has a mount file system on it (although not every
mounted file system sets bd_super), but that also implies it doesn't even
have partitions to start with.
So instead of trying to come up with a logical check for all openers,
just remove the check entirely.

We better warn the fibmap user and not return a truncated and therefore
an incorrect block map address if the bmap() returned block address
is greater than INT_MAX (since user supplied integer pointer).
It's better to pr_warn() all user of ioctl_fibmap() and return a proper
error code rather than silently letting a FS corruption happen if the
user tries to fiddle around with the returned block map address.
We fix this by returning an error code of -ERANGE and returning 0 as the
block mapping address in case if it is > INT_MAX.
Now iomap_bmap() could be called from either of these two paths.
Either when a user is calling an ioctl_fibmap() interface to get
the block mapping address or by some filesystem via use of bmap()
internal kernel API.
bmap() kernel API is well equipped with handling of u64 addresses.
WARN condition in iomap_bmap_actor() was mainly added to warn all
the fibmap users. But now that we have directly added this warning
for all fibmap users and also made sure to return 0 as block map address
in case if addr > INT_MAX.
So we can now remove this logic from iomap_bmap_actor().

In AST2600 there have a slow peripheral bus between CPU and i2c
controller. Therefore GIC i2c interrupt status clear have delay timing,
when CPU issue write clear i2c controller interrupt status. To avoid
this issue, the driver need have read after write clear at i2c ISR.
