+Subject: [PATCH] powerpc: change the memory size limit
+
+When run "kexec" in powerpc board, the kexec has a limit that
+the kernel text and bss size must be less than 24M. But now
+some kernel size exceed the limit. So we need to change the limit,
+else will get the error log as below:
+
+my_load:669: do
+Could not find a free area of memory of 0x12400 bytes...
+Could not find a free area of memory of 0x13000 bytes...
+locate_hole failed
