commit 396a66aa1172ef2b78c21651f59b40b87b2e5e1e upstream.
gcc-11 warns about mismatched prototypes here:
arch/x86/lib/msr-smp.c:255:51: error: argument 2 of type ‘u32 *’ {aka ‘unsigned int *’} declared as a pointer [-Werror=array-parameter=]
255 | int rdmsr_safe_regs_on_cpu(unsigned int cpu, u32 *regs)
| ~~~~~^~~~
arch/x86/include/asm/msr.h:347:50: note: previously declared as an array ‘u32[8]’ {aka ‘unsigned int[8]’}
GCC is right here - fix up the types.
[ mingo: Twiddled the changelog. ]
