Subject: x86: Nuke the supervisor_stack field in i386 thread_info
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2432e1364bbee83cb6e63e026c91785031704ba5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

x86: Nuke the supervisor_stack field in i386 thread_info

Nothing references the supervisor_stack in the thread_info field,
and it does not exist in x86_64. To make the two more the same,
it is being removed.
