arch, mm: move definition of node_data to generic code

2024-09-04T04:15:28+00:00

Every architecture that supports NUMA defines node_data in the same way:

	struct pglist_data *node_data[MAX_NUMNODES];

No reason to keep multiple copies of this definition and its forward
declarations, especially when such forward declaration is the only thing
in include/asm/mmzone.h for many architectures.

Add definition and declaration of node_data to generic code and drop
architecture-specific versions.

MIPS: sgi-ip27: make NODE_DATA() the same as on all other architectures

2024-09-04T04:15:26+00:00

sgi-ip27 is the only system that defines NODE_DATA() differently than the
rest of NUMA machines.

Add node_data array of struct pglist pointers that will point to
__node_data[node]->pglist and redefine NODE_DATA() to use node_data array.

This will allow pulling declaration of node_data to the generic mm code in
the next commit.

MIPS: IP27: Remove incorrect `cpu_has_fpu' override

2022-05-04T20:23:14+00:00

Remove unsupported forcing of `cpu_has_fpu' to 1, which makes the `nofpu'
kernel parameter non-functional, and also causes a link error:

ld: arch/mips/kernel/traps.o: in function `trap_init':
./arch/mips/include/asm/msa.h:(.init.text+0x348): undefined reference to `handle_fpe'
ld: ./arch/mips/include/asm/msa.h:(.init.text+0x354): undefined reference to `handle_fpe'
ld: ./arch/mips/include/asm/msa.h:(.init.text+0x360): undefined reference to `handle_fpe'

where the CONFIG_MIPS_FP_SUPPORT configuration option has been disabled.
