\| \| *	[ARM] 5428/1: Module relocation update for R_ARM_V4BX	Daniel Silverstone	2009-03-21	1	-0/+9
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	It would seem when building kernel modules with modern binutils (required by modern GCC) for ARM v4T targets (specifically observed with the Samsung 24xx SoC which is an 920T) R_ARM_V4BX relocations are emitted for function epilogues. This manifests at module load time with an "unknown relocation: 40" error message. The following patch adds the R_ARM_V4BX relocation to the ARM kernel module loader. The relocation operation is taken from that within the binutils bfd library.

There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

This removes the array of dma structures in the central multiplexer, replacing it with an array of pointers instead; this is more flexible since it allows the drivers to wrap the DMA structure (eventually allowing us to transition non-ISA DMA drivers away.)

Compile tested for powerpc32, compile/boot tested for powerpc64. * ia64: can use generic PERCPU_VADDR() macro. __phys_per_cpu_start is identical to __per_cpu_load. Compile tested and symbol table looks identical after the change except for the additional __per_cpu_load. * arm: added explicit __per_cpu_load definition. Currently uses unified .init output section so can't use the generic macro. Dunno whether the unified .init ouput section is required by arch peculiarity so I left it alone.
