UBUNTU: SAUCE: s390/bpf: Fix optimizing out zero-extensions

BugLink: https://bugs.launchpad.net/bugs/1943960 (s390x BPF JIT vulnerabilities (LP: #1943960))

Currently the JIT completely removes things like `reg32 += 0`,
however, the BPF_ALU semantics requires the target register to be
zero-extended in such cases.

Fix by optimizing out only the arithmetic operation, but not the
subsequent zero-extension.

UBUNTU: SAUCE: s390/bpf: Fix 64-bit subtraction of the -0x80000000 constant

BugLink: https://bugs.launchpad.net/bugs/1943960 (s390x BPF JIT vulnerabilities (LP: #1943960))

The JIT uses agfi for subtracting constants, but -(-0x80000000) cannot
be represented as a 32-bit signed binary integer. Fix by using algfi in
this particular case.

Revert "ACPI: resources: Add checks for ACPI IRQ override"

BugLink: https://bugs.launchpad.net/bugs/1941657

The commit 0ec4e55e9f57 ("ACPI: resources: Add checks for ACPI IRQ
override") introduces regression on some platforms, at least it makes
the UART can't get correct irq setting on two different platforms,
and it makes the kernel can't bootup on these two platforms.

This reverts commit 0ec4e55e9f571f08970ed115ec0addc691eda613.
