There are two duplicate `-O binary` flags when objcopying from vmlinux
to Image/xipImage.
RISC-V set `-O binary` flag in both OBJCOPYFLAGS in the top-level riscv
Makefile and OBJCOPYFLAGS_* in the boot/Makefile, and the objcopy cmd
in Kbuild would join them together.
The `-O binary` flag is only needed for objcopying Image, so remove the
OBJCOPYFLAGS in the top-level riscv Makefile.

Fei has reported that KASAN triggers during apply_alternatives() on
a 5-level paging machine:
BUG: KASAN: out-of-bounds in rcu_is_watching()
Read of size 4 at addr ff110003ee6419a0 by task swapper/0/0
...
__asan_load4()
rcu_is_watching()
trace_hardirqs_on()
text_poke_early()
apply_alternatives()
...
On machines with 5-level paging, cpu_feature_enabled(X86_FEATURE_LA57)
gets patched. It includes KASAN code, where KASAN_SHADOW_START depends on
__VIRTUAL_MASK_SHIFT, which is defined with cpu_feature_enabled().
KASAN gets confused when apply_alternatives() patches the
KASAN_SHADOW_START users. A test patch that makes KASAN_SHADOW_START
static, by replacing __VIRTUAL_MASK_SHIFT with 56, works around the issue.
Fix it for real by disabling KASAN while the kernel is patching alternatives.

The alternative stack checking in get_sigframe introduced by the Vector
support is not needed and has a problem. It is not needed as we have
already validate it at the beginning of the function if we are already
on an altstack. If not, the size of an altstack is always validated at
its allocation stage with sigaltstack_size_valid().
Besides, we must only regard the size of an altstack if the handler of a
signal is registered with SA_ONSTACK. So, blindly checking overflow of
an altstack if sas_ss_size not equals to zero will check against wrong
signal handlers if only a subset of signals are registered with
SA_ONSTACK.

that we send discard bios sorted in order from longest to shortest, like

Provide common prototypes for arch_register_cpu() and

versions, so the prototype for this is already set. It is generally not
necessary for function prototypes to be conditional on preprocessor macros.
Some architectures (e.g. Loongarch) are missing the prototype for this, and
rather than add it to Loongarch's asm/cpu.h, do the job once for everyone.
Since this covers everyone, remove the now unnecessary prototypes in

On some OEM systems, adding a W7900 dGPU triggers RAS errors and hangs
at a black screen on startup. This issue occurs only if `ucsi_acpi` has
loaded before `amdgpu` has loaded. The reason for this failure is that
`amdgpu` uses power_supply_is_system_supplied() to determine if running
on AC or DC power at startup. If this value is reported incorrectly the
dGPU will also be programmed incorrectly and trigger errors.
power_supply_is_system_supplied() reports the wrong value because UCSI
power supplies provided as part of the system don't properly report the
scope as "DEVICE" scope (not powering the system).
In order to fix this issue check the capabilities reported from the UCSI
power supply to ensure that it supports charging a battery and that it can
be powered by AC. Mark the scope accordingly.

While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure, including of course, the flexible-array member.

SMC_STAT_PAYLOAD_SUB(_smc_stats, _tech, key, _len, _rc) will calculate
wrong bucket positions for payloads of exactly 4096 bytes and
(1 << (m + 12)) bytes, with m == SMC_BUF_MAX - 1.
Intended bucket distribution:
Assume l == size of payload, m == SMC_BUF_MAX - 1.
Bucket 0 : 0 < l <= 2^13
Bucket n, 1 <= n <= m-1 : 2^(n+12) < l <= 2^(n+13)
Bucket m : l > 2^(m+12)
Current solution:
_pos = fls64((l) >> 13)
[...]
_pos = (_pos < m) ? ((l == 1 << (_pos + 12)) ? _pos - 1 : _pos) : m
For l == 4096, _pos == -1, but should be _pos == 0.
For l == (1 << (m + 12)), _pos == m, but should be _pos == m - 1.
In order to avoid special treatment of these corner cases, the
calculation is adjusted. The new solution first subtracts the length by
one, and then calculates the correct bucket by shifting accordingly,
i.e. _pos = fls64((l - 1) >> 13), l > 0.
This not only fixes the issues named above, but also makes the whole
bucket assignment easier to follow.
Same is done for SMC_STAT_RMB_SIZE_SUB(_smc_stats, _tech, k, _len),
where the calculation of the bucket position is similar to the one
