385 * GET_DESC_BASE reads the descriptor base of the specified segment.

387 * Args:
388 * idx - descriptor index
389 * gdt - GDT pointer
390 * base - 32bit register to which the base will be written
391 * lo_w - lo word of the "base" register
392 * lo_b - lo byte of the "base" register
393 * hi_b - hi byte of the low word of the "base" register

395 * Example:
396 * GET_DESC_BASE(GDT_ENTRY_ESPFIX_SS, %ebx, %eax, %ax, %al, %ah)
397 * Will read the base address of GDT_ENTRY_ESPFIX_SS and put it into %eax.
