upstart writes in with an IRC submission for Runaway1956:

Linux x86/x86_64 Will Now Always Reserve The First 1MB Of RAM - Phoronix:

The Linux x86/x86_64 kernel code already had logic in place for reserving portions of the first 1MB of RAM to avoid the BIOS or kernel potentially clobbering that space among other reasons while now Linux 5.13 is doing away with that "wankery" and will just unconditionally always reserve the first 1MB of RAM.

[...] The motivation now for Linux 5.13 in getting that 1MB unconditional reservation in place for Linux x86/x86_64 stems from a bug report around an AMD Ryzen system being unbootable on Linux 5.13 since the change to consolidate their early memory reservations handling. Just unconditionally doing the first 1MB makes things much simpler to handle.

The change was sent in this morning as part of x86/urgent. "Do away with all the wankery of reserving X amount of memory in the first megabyte to prevent BIOS corrupting it and simply and unconditionally reserve the whole first megabyte."

no more wankery

    That doesn't protect your system from all the undocumented opcodes and other fuckery the Jews bake into their processors and chipsets. And just in time for mass ransomware attacks that we all must "get used to." Jews must be hard-up for extra avenues of money-laundering now that there's a bigger spotlight on their human trafficking since BiBi's blackmail network was shut down.

    Oh no, it's those Russian Hackers again!

    Gee whiz. You help the Romans execute just *one* messiah and you never hear the end of it. Let it go, man.

      No, you're thinking of the Dead Messiah Sketch: "The only reason that he had been up on that cross in the first place was that he had been NAILED there...".
