These two commits are required to build the linux-5.15.y branch successfully with GCC 13 in my testing. Both are backports from mainline, with a couple of tweaks to make them apply cleanly.
The result has been build tested against a few different gcc versions (9.5, 11.3 & 13.1) and defconfigs (x86_64_defconfig, i386_defconfig, ARM multi_v7_defconfig, ARM64 defconfig, RISCV defconfig, RISCV rv32_defconfig) via Yocto Project builds.
Patches for linux-5.10.y are also on the way.

base-commit: d7af3e5ba454d007b4939f858739cf1cecdeab46
From: Arnd Bergmann arnd@arndb.de
commit f07788079f515ca4a681c5f595bdad19cfbd7b1d upstream.
gcc-13 slightly changes the type of constant expressions that are defined in an enum, which triggers a compile time sanity check in libata:
linux/drivers/ata/libahci.c: In function 'ahci_led_store': linux/include/linux/compiler_types.h:357:45: error: call to '__compiletime_assert_302' declared with attribute error: BUILD_BUG_ON failed: sizeof(_s) > sizeof(long) 357 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)
The new behavior is that sizeof() returns the same value for the constant as it does for the enum type, which is generally more sensible and consistent.
The problem in libata is that it contains a single enum definition for lots of unrelated constants, some of which are large positive (unsigned) integers like 0xffffffff, while others like (1<<31) are interpreted as negative integers, and this forces the enum type to become 64 bit wide even though most constants would still fit into a signed 32-bit 'int'.
Fix this by changing the entire enum definition to use BIT(x) in place of (1<<x), which results in all values being seen as 'unsigned' and fitting into an unsigned 32-bit type.

The result has been build tested against a few different gcc versions (9.5, 11.3 & 13.1) and defconfigs (x86_64_defconfig, i386_defconfig, ARM multi_v7_defconfig, ARM64 defconfig, RISCV defconfig, RISCV rv32_defconfig) via Yocto Project builds.
This is great, but I still can't build 'make allmodconfig' for 5.15 with these patches, but the number of errors is much smaller now. I'll work to winnow them down to try to fix this so that I don't have to keep older versions of gcc around on my test-build systems.
