Venkataraman" <madvenka@linux.microsoft.com> The ORC code needs to be reorganized into arch-specific and generic parts so that architectures other than X86 can use the generic parts. orc_types.h contains the following ORC definitions shared between objtool and the kernel: - ORC register definitions which are arch-specific. - orc_entry structure which is generic. Move orc_entry into a new file include/linux/orc_entry.h. Also, the field names bp_reg and bp_offset in struct orc_entry are x86-specific. Change them to fp_reg and fp_offset. FP stands for frame pointer. Currently, the type field in orc_entry is only 2 bits. For other architectures, we will need more. So, expand this to 3 bits. Signed-off-by: Madhavan T.
