It affects WAY more ARM processors than A75. All the fast ARM cores are vulnerable to one of the two meltdown flaws and half are vulnerable to a subset of the third flaw (with A75 being completely vulnerable).

Do you mean Spectre? Meltdown is the Variant 3 in that link.

The ARM cores listed on that page are not all the ARM cores in the market (or running in the real-world). There are many more ARM cores than listen in that table, and the page says any ARM core not listed in that table is not vulnerable to any variant of Meltdown or Spectre.
