m68k: Define sigcontext ABI of ColdFire
The following patch defines sigcontext ABI of ColdFire. Due to ISA
restrictions ColdFire needs different rt_sigreturn trampoline.
And due to ColdFire FP registers being 8-bytes instead of 12-bytes on
m68k, sigcontext and fpregset structures should be updated.
Regarding the sc_fpstate[16+6*8] field, it would've been enough 16
bytes to store ColdFire's FP state. To accomodate GLIBC's libSegFault
it would'be been enough 6*8 bytes (room for the 6 non-call-clobbered
FP registers). I set it to 16+6*8 to provide some extra space for any
future changes in the ColdFire FPU.

GT-64111.
I think this is the approach Ben Herrenschmidt suggested long ago:

This allows us to remove the IORESOURCE_PCI_FIXED hack from

addresses. IORESOURCE_PCI_FIXED denotes resources that can't be moved;
it has nothing to do with converting bus to CPU addresses.

area. Currently, addresses at the far end of the 32bit area are assumed

Because the VIA SuperIO chip only decodes 24 bits of address space but port
address space currently being configured as 32MB there is the theoretical
possibility of aliases within the I/O port address range.
The complicated solution is to reserve all address range that potencially
could cause such aliases. But with the PCI spec limiting port allocations

way more than one would ever expect to be used so we just reduce the port

Staging: Octeon: Free transmit SKBs in a timely manner
If we wait for the once-per-second cleanup to free transmit SKBs,
sockets with small transmit buffer sizes might spend most of their
time blocked waiting for the cleanup.
Normally we do a cleanup for each transmitted packet. We add a
watchdog type timer so that we also schedule a timeout for 150uS after
a packet is transmitted. The watchdog is reset for each transmitted
packet, so for high packet rates, it never expires. At these high
rates, the cleanups are done for each packet so the extra watchdog
initiated cleanups are neither needed nor triggered.
