x86/alternatives: Fix build warning
Fixes these warnings:
arch/x86/kernel/alternative.c: In function 'alternatives_text_reserved': arch/x86/kernel/alternative.c:402: warning: comparison of distinct pointer types lacks a cast arch/x86/kernel/alternative.c:402: warning: comparison of distinct pointer types lacks a cast arch/x86/kernel/alternative.c:405: warning: comparison of distinct pointer types lacks a cast arch/x86/kernel/alternative.c:405: warning: comparison of distinct pointer types lacks a cast
Caused by:
2cfa197: ftrace/alternatives: Introducing *_text_reserved functions
Changes in v2: - Use local variables to compare, instead of type casts.
