static inline bool is_early_uv_system(void) { return !((efi.uv_systab == EFI_INVALID_TABLE_ADDR) || !efi.uv_systab);
No need for the inner braces here.
But woudn't this be nicer as:
return efi.uv_systab != EFI_INVALID_TABLE_ADDR && efi.uv_systab;
anyway?
+#define is_uv_hubless _is_uv_hubless
Why the weird macro indirection?
-static inline int is_uv_hubless(void) { return 0; } +static inline int _is_uv_hubless(int uv) { return 0; } +#define is_uv_hubless _is_uv_hubless
And here again.
