The Microblaze dynamic ftrace code assumes a call ordering that is not met
in all scenarios. Specifically, executing a command similar to:echo 105 > /sys/kernel/debug/tracing/set_ftrace_pid
before any other tracing-related commands results in a kernel panic:
BUG: failure at arch/microblaze/kernel/ftrace.c:198/ftrace_update_ftrace_func()!
Recoding ftrace_update_ftrace_func() to use &ftrace_caller directly eliminates
the need to capture its address elsewhere (and thus rely on a particular call
sequence).Signed-off-by: Steven J. Magnani

When the system has no lmb bram, main memory should be start from
zero because of microblaze vectors.DTS fragment could look like:
DDR2_SDRAM: memory@0 {
device_type = "memory";
reg = < 0x0 0x10000000 >;
} ;Then you have to setup CONFIG_KERNEL_BASE_ADDR=0 which caused
that kernel physical start address will be zero. On reset vector place
will be jump to 0x100 and on 0x100 starts kernel text.You have to solve how to load the kernel before cpu starts.
Tested with XMD.Signed-off-by: Michal Simek
