x86/mce: Fix build bug with CONFIG_PROVE_LOCKING=y && CONFIG_X86_MCE_INTEL=y
Commit f56e8a07 "x86/mce: Fix RCU lockdep splats" introduced the following build bug: arch/x86/kernel/cpu/mcheck/mce.c: In function 'mce_log': arch/x86/kernel/cpu/mcheck/mce.c:166: error: 'mce_read_mutex' undeclared (first use in this function) arch/x86/kernel/cpu/mcheck/mce.c:166: error: (Each undeclared identifier is reported only once arch/x86/kernel/cpu/mcheck/mce.c:166: error: for each function it appears in.) Move the in-the-middle-of-file lock variable up to the variable definition section, the top of the .c file. Cc: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Cc: "H.
