      [PATCH] lockdep: special s390 print_symbol() version · b02454f4
      由 Heiko Carstens 提交于 
      Have a special version of print_symbol() for s390 which clears the most
significant bit of addr before calling __print_symbol().  This seems to be
better than checking/changing each place in the kernel that saves an
instruction pointer.

Without this the output would look like:

hardirqs last  enabled at (30907): [<80018c6a>] 0x80018c6a
hardirqs last disabled at (30908): [<8001e48c>] 0x8001e48c

softirqs last disabled at (30897): [<8001dc50>] 0x8001dc50

instead of this:

      [PATCH] time initialisation fix · 88fecaa2
      由 john stultz 提交于 
      We're not reay to take a timer interrupt until timekeeping_init() has run.
But time_init() will start the time interrupt and if it is called with
local interrupts enabled we'll immediately take an interrupt and die.

Fix that by running timekeeping_init() prior to time_init().

We don't know _why_ local interrupts got enabled on Jesse Brandeburg's
machine.  That's a separate as-yet-unsolved problem.  THe patch adds a little
bit of debugging to detect that.

This whole requirement that local interrupts be held off during early boot
keeps on biting us.
