Subject: [IA64] Low byte of current->personality is not a bitmask.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ff67b59726a8cd3549b069dfa78de2f538d3b8e3;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[IA64] Low byte of current->personality is not a bitmask.

Peter Staubach pointed out that it is not correct to check
current->personality & PER_LINUX32 (this will have false
hits on several other personality values).
