Subject: x86/asm/entry: Fix remaining use of SYSCALL_VECTOR
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f435e68fe74d41a34124e49c07ff9f9cd7954e35;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

x86/asm/entry: Fix remaining use of SYSCALL_VECTOR

Commit:

  51bb92843edc ("x86/asm/entry: Remove SYSCALL_VECTOR")

Converted most uses of SYSCALL_VECTOR to IA32_SYSCALL_VECTOR, but
forgot about lguest.
