Subject: sh: Populate initial secondary CPU info from boot_cpu_data.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a66c2edea56c291a6f6a52f07496ebb97c0880e8;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

sh: Populate initial secondary CPU info from boot_cpu_data.

The secondary CPU info was seeing corrupted results due to not entering
all of the setup paths taken by the boot CPU. So we just memcpy() the
boot cpu data over directly, and then fix up the per-CPU bits.
