+Subject: alpha: fix build failures
+
+From: Sudip Mukherjee <sudipm.mukherjee@gmail.com>
+
+commit 8ee912dab95f1483156b6e994004bfcc3158d798 upstream.
+
+The build of alpha allmodconfig is giving error:
+
+ arch/alpha/include/asm/mmu_context.h: In function 'ev5_switch_mm':
+ arch/alpha/include/asm/mmu_context.h:160:2: error:
+ implicit declaration of function 'task_thread_info';
+ did you mean 'init_thread_info'? [-Werror=implicit-function-declaration]
+
+The file 'mmu_context.h' needed an extra header file.
