      microblaze: Rename global function heartbeat() · 79c157a3
      由 Guenter Roeck 提交于 
      microblaze:allmodconfig complains for some configurations that 'heartbeat'
is redefined as different kind of symbol. This is seen in test compiles
of watchdog drivers, which often use 'heartbeat' as ststic variable.

Since 'heartbeat' is an unfortunate name for a global function,
rename it to microblaze_heartbeat. Also rename the setup function
to microblaze_setup_heartbeat.

      of: remove HAVE_ARCH_DEVTREE_FIXUPS · 32df8dca
      由 Rob Herring 提交于 
      HAVE_ARCH_DEVTREE_FIXUPS appears to always be needed except for sparc,
but it is only used for /proc/device-teee and sparc does not enable
/proc/device-tree. So this option is redundant. Remove the option and
always enable it. This has the side effect of fixing /proc/device-tree
on arches such as arm64 which failed to define this option.

Example:

Current wrong implementation
0xbfff ffff >= (0xbfff fff0 | 0x10 | (0xbfff fff0 + 0x10))
0xbfff ffff >= (0xbfff fff0        | 0xc000 0000)
0xbfff ffff >= 0xf000 0000
return 0 which is access failed even the combination is valid.
because get_fs().seq returns the last valid address.

This patch fix this problem.

Size equals to zero is valid access.
