Subject: RE: [PATCH v2 1/3] module: Rename module_alloc() to text_alloc() and move to kernel proper

That could be handled by an arch-specific inline wrapper in a .h file.
Although I actually suspect the nios2 code is just being lazy.
The processor is a very simple in-order 32bit soft cpu for Intel (Altera)
FPGA.
We have four nios2 cpu on one of our fpga images - all running small
(almost single function) code loops.
I can't imagine actually trying to run Linux on one to do anything
useful - clock speed is unlikely to be much above 100MHz.
We can't meet timing at 125MHZ (I've tried quite hard) so have
to run at 62.5MHz because of the PCIe clock.
