There are other special register that cause build warnings and may as
well need renaming as well.

Now that binutils generate *.unlikely sections which don't follow
documented (info as) literal section naming rules, section name
transformation script doesn't work well resulting in the following
errors at vmlinux link time:
main.c:(.text.unlikely+0x3): dangerous relocation: l32r: literal
placed after use: .literal.unlikely
Fix section name transformation script by adding specific rule for
.text.unlikely sections.

This patch fixes an assumption that cclk's initial divisor will always be 1 (or
0 in the register). TSCALE is always initialized on startup with a value of 4
regardless of the inital cclk divisor; so, we can't make the assumption without
making lots of other assumptions. The TPERIOD value is set with a value of the
current cclk (value / (HZ * TSCALE)) - 1; so, we need to adjust based on this
initial frequency and not use cclk's initial divisor for adjusting the tscale.

Pull MIPS update from Ralf Baechle:
"This is the MIPS update for 3.7.
A fair chunk of them are platform updates to the Cavium Octeon SOC
(which involves machine generated header files of considerable size),
Atheros ATH79xx, RMI aka Netlogic aka Broadcom XLP, Broadcom BCM63xx
platforms.
Support for the commercial MIPS simulator MIPSsim has been removed as
MIPS Technologies is shifting away from this product and Qemu is
offering various more powerful platforms. The generic MIPS code can
now also probe for no-execute / write-only TLB features implemented
without the full SmartMIPS extension as permitted by the latest MIPS
processor architecture. Lots of small changes to generic code."
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (78 commits)
MIPS: ath79: Fix CPU/DDR frequency calculation for SRIF PLLs
MIPS: ath79: use correct fractional dividers for {CPU,DDR}_PLL on AR934x
MIPS: BCM63XX: Properly handle mac address octet overflow
MIPS: Kconfig: Avoid build errors by hiding USE_OF from the user.
MIPS: Replace `-' in defconfig filename wth `_' for consistency.
MIPS: Wire kcmp syscall.
MIPS: MIPSsim: Remove the MIPSsim platform.
MIPS: NOTIFY_RESUME is not needed in TIF masks
MIPS: Merge the identical "return from syscall" per-ABI code
MIPS: Unobfuscate _TIF..._MASK
MIPS: Prevent hitting do_notify_resume() with !user_mode(regs).
MIPS: Replace 'kernel_uses_smartmips_rixi' with 'cpu_has_rixi'.
MIPS: Add base architecture support for RI and XI.
MIPS: Optimise TLB handlers for MIPS32/64 R2 cores.
MIPS: uasm: Add INS and EXT instructions.
MIPS: Avoid pipeline stalls on some MIPS32R2 cores.
MIPS: Make VPE count to be one-based.
MIPS: Add new end of interrupt functionality for GIC.
MIPS: Add EIC support for GIC.
MIPS: Code clean-ups for the GIC.

Besides the CPU and DDR PLLs, the CPU and DDR frequencies
can be derived from other PLLs in the SRIF block on the
AR934x SoCs. The current code does not checks if the SRIF
PLLs are used and this can lead to incorrectly calculated
CPU/DDR frequencies.
Fix it by calculating the frequencies from SRIF PLLs if
those are used on a given board.

The current dividers in the code are wrong and this
leads to broken CPU frequency calculation on boards
where the fractional part is used.
For example, if the SoC is running from a 40MHz
reference clock, refdiv=1, nint=14, outdiv=0 and
nfrac=31 the real frequency is 579.375MHz but the
current code calculates 569.687MHz instead.
Because the system time is indirectly related to
the CPU frequency the broken computation causes
drift in the system time.
The correct divider is 2^6 for the CPU PLL and 2^10
for the DDR PLL. Use the correct values to fix the
issue.
