* Notes:
+ * - PLT stub handling
+ * On 32bit (and sometimes 64bit) and with big kernel modules like xfs or
+ * ipv6 the relocation types R_PARISC_PCREL17F and R_PARISC_PCREL22F may
+ * fail to reach their PLT stub if we only create one big stub array for

+ * Instead we now insert individual PLT stub entries directly in front of
+ * of the code sections where the stubs are actually called.
+ * This reduces the distance between the PCREL location and the stub entry
+ * so that the relocations can be fulfilled.
+ * While calculating the final layout of the kernel module in memory, the
+ * kernel module loader calls arch_mod_section_prepend() to request the
+ * to be reserved amount of memory in front of each individual section.

* - SEGREL32 handling
* We are not doing SEGREL32 handling correctly. According to the ABI, we
* should do a value offset, like this:

- CCID 2, TCP-like Congestion Control, denotes Additive Increase,
- Multiplicative Decrease (AIMD) congestion control with behavior
- modelled directly on TCP, including congestion window, slow start,
- timeouts, and so forth [RFC 2581]. CCID 2 achieves maximum
- bandwidth over the long term, consistent with the use of end-to-end
- congestion control, but halves its congestion window in response to
- each congestion event. This leads to the abrupt rate changes
- typical of TCP. Applications should use CCID 2 if they prefer
- maximum bandwidth utilization to steadiness of rate. This is often
- the case for applications that are not playing their data directly
- to the user. For example, a hypothetical application that
- transferred files over DCCP, using application-level retransmissions
- for lost packets, would prefer CCID 2 to CCID 3. On-line games may
- also prefer CCID 2. See RFC 4341 for further details.
