Subject: x86/acrn: Remove redundant chars from ACRN signature
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4c7bfa383efd837d4ab8f86ef05886959ed8bfe5;p=linux.git

x86/acrn: Remove redundant chars from ACRN signature

hypervisor_cpuid_base() only handles 12 chars of the hypervisor
signature string but is provided with 14 chars.

Remove the redundancy. Additionally, replace the user space uint32_t
with preferred kernel type u32.
