      x86/microcode: Get rid of find_cpio_data()'s dummy offset arg · 852ad5b9
      由 Borislav Petkov 提交于 
      The microcode loader doesn't use it and now that that arg has been made
optional in find_cpio_data(), get rid of it here.

No functionality change.

      x86/microcode: Fix loading precedence · 6c545647
      由 Borislav Petkov 提交于 
      So it can happen that even with builtin microcode,
CONFIG_BLK_DEV_INITRD=y gets forgotten enabled.

Or, even with that disabled, an initrd image gets supplied by the boot
loader, by omission or is simply forgotten there. And since we do look
at boot_params.hdr.ramdisk_* to know whether we have received an initrd,
we might get puzzled.

So let's just make the loader look for builtin microcode first and if
found, ignore the ramdisk image.

If no builtin found, it falls back to scanning the supplied initrd, of
course.

For that, we move all the initrd scanning in a separate
__scan_microcode_initrd() function and fall back to it only if
load_builtin_intel_microcode() has failed.

      Remove the remaining module functionality leftovers. Make
"dis_ucode_ldr" an early_param and make it static again. Drop
module aliases, autoloading table, description, etc.

Bump version number, while at it.

      由 Borislav Petkov 提交于 
      Merge the early loader functionality into the driver proper. The
diff is huge but logically, it is simply moving code from the
_early.c files into the main driver.

      x86/microcode: Unmodularize the microcode driver · 9a2bc335
      由 Borislav Petkov 提交于 
      Make CONFIG_MICROCODE a bool. It was practically a bool already anyway,
since early loader was forcing it to =y.

Regardless, there's no real reason to have something be a module which
gets built-in on the majority of installations out there. And its not
like there's noticeable change in functionality - we still can load late
microcode - just the module glue disappears.

      x86, microcode, AMD: Fix early microcode loading · 84516098
      由 Torsten Kaiser 提交于 
      load_microcode_amd() (and the helper it is using) should not have an
cpu parameter. The microcode loading does not depend on the CPU wrt the
patches loaded since they will end up in a global list for all CPUs
anyway.

The change from cpu to x86family in load_microcode_amd()
now allows to drop the code messing with cpu_data(cpu) from
collect_cpu_info_amd_early(), which is wrong anyway because at that
point the per-cpu cpu_info is not yet setup (These values would later be
overwritten by smp_store_boot_cpu_info() / smp_store_cpu_info()).

Fold the rest of collect_cpu_info_amd_early() into load_ucode_amd_ap(),
because its only used at one place and without the cpuinfo_x86 accesses
it was not much left.
