#     powerpc/module_64: Use special stub for _mcount() with -mprofile-kernel
#     
#     Since commit c55d7b5e64265f ("powerpc: Remove STRICT_KERNEL_RWX
#     incompatibility with RELOCATABLE"), powerpc kernels with
#     -mprofile-kernel can crash in certain scenarios with a trace like below:
#     
#         BUG: Unable to handle kernel instruction fetch (NULL pointer?)
#         Faulting instruction address: 0x00000000
#         Oops: Kernel access of bad area, sig: 11 [#1]

#     
#     The NIP points to NULL, or a random location (data even), while the LR
#     always points to the LEP of a function (with an offset of 8), indicating
#     that something went wrong with ftrace. However, ftrace is not
#     necessarily active when such crashes occur.
#     
#     The kernel OOPS sometimes follows a warning from ftrace indicating that
#     some module functions could not be patched with a nop. Other times, if a
#     module is loaded early during boot, instruction patching can fail due to
#     a separate bug, but the error is not reported due to missing error
#     reporting.
#     
#     In all the above cases when instruction patching fails, ftrace will be
#     disabled but certain kernel module functions will be left with default
#     calls to _mcount(). This is not a problem with ELFv1. However, with
#     -mprofile-kernel, the default stub is problematic since it depends on a
#     valid module TOC in r2. If the kernel (or a different module) calls into
#     a function that does not use the TOC, the function won't have a prologue
#     to setup the module TOC. When that function calls into _mcount(), we
#     will end up in the relocation stub that will use the previous TOC, and
#     end up trying to jump into a random location. From the above trace:
#     
#             iomap_apply+0x20c/0x920 [kernel TOC]
#                             |
#                             V
#             ext4_iomap_end+0x8/0x30 [no GEP == kernel TOC]
#                             |
#                             V
#                     _mcount() stub
#             [uses kernel TOC -> random entry]
#     
#     To address this, let's change over to using the special stub that is
#     used for ftrace_[regs_]caller() for _mcount(). This ensures that we are
#     not dependent on a valid module TOC in r2 for default _mcount()
#     handling.
