SubjectRe: [RFC] amd64_edac: syndromes loading

Yeah, I was thinking maybe drivers/edac/amd64_x(4|8).bin or so.

Alternatively, we could make the syndromes builtin thus removing the
requirement to go to userspace for the loading. For that we'll need
two new .c files in drivers/edac/ which represent the x4 and x8 tables
respectively:

unsigned short x8_raw_data[] = {
0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000,
0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000,
0x0000, 0x0100, 0x0001, 0x0101, 0x01B8, 0x015C, 0x012E, 0x01C6, 0x0163,
0x01FD, 0x0189, 0x019D, 0xB801, 0x5C01, 0x2E01, 0xC601, 0x6301, 0xFD01,
0x8901, 0x9D01, 0x0200, 0x0002, 0x0202, 0x0201, 0x02B8, 0x025C, 0x02FD,
....

The drawback with these is that they'll always be builtin, enlarging
kernel code by 10-15K although only one of them is in use.
