[PATCH] dump_thread() cleanup
Browse files Browse the repository at this point in the history 
)

From: Adrian Bunk <[email protected]>

- create one common dump_thread() prototype in kernel.h

- dump_thread() is only used in fs/binfmt_aout.c and can therefore be
  removed on all architectures where CONFIG_BINFMT_AOUT is not
  available
