Add __init to reserve_memory_end, reserve_oldmem and remove_oldmem. Sometimes these functions are not inlined, and then the build complains about section mismatch.

[ Upstream commit 21653a4181ff292480599dad996a2b759ccf050f ]
Some ACPI i2c-devices _STA method (which is used to detect if the device is present) use autodetection code which probes which device is present over i2c. This requires the I2C ACPI OpRegion handler to be registered before we enumerate i2c-clients under the i2c-adapter.
This fixes the i2c touchpad on the Lenovo ThinkBook 14-IIL and ThinkBook 15 IIL not getting an i2c-client instantiated and thus not working.

[ Upstream commit db6c6a0df840e3f52c84cc302cc1a08ba11a4416 ]
When a function is annotated with STACK_FRAME_NON_STANDARD, objtool doesn't validate its code paths. It also skips sibling call detection within the function.
But sibling call detection is actually needed for the case where the ignored function doesn't have any return instructions. Otherwise objtool naively marks the function as implicit static noreturn, which affects the reachability of its callers, resulting in "unreachable instruction" warnings.
Fix it by just enabling sibling call detection for ignored functions. The 'insn->ignore' check in add_jump_destinations() is no longer needed after
e6da9567959e ("objtool: Don't use ignore flag for fake jumps").
Fixes the following warning:
arch/x86/kvm/vmx/vmx.o: warning: objtool: vmx_handle_exit_irqoff()+0x142: unreachable instruction
which triggers on an allmodconfig with CONFIG_GCOV_KERNEL unset.
