  - efi: runtime: avoid EFIv2 runtime services on Apple x86 machines Aditya reports [0] that his recent     MacbookPro crashes in the firmware when using the variable services at runtime. The culprit appears to be     a call to QueryVariableInfo(), which we did not use to call on Apple x86 machines in the past as they only     upgraded from EFI v1.10 to EFI v2.40 firmware fairly recently, and QueryVariableInfo() (along with     UpdateCapsule() et al) was added in EFI v2.00. The only runtime service introduced in EFI v2.00 that we     actually use in Linux is QueryVariableInfo(), as the capsule based ones are optional, generally not used     at runtime (all the LVFS/fwupd firmware update infrastructure uses helper EFI programs that invoke capsule     update at boot time, not runtime), and not implemented by Apple machines in the first place.
    QueryVariableInfo() is used to 'safely' set variables, i.e., only when there is enough space. This     prevents machines with buggy firmwares from corrupting their NVRAMs when they run out of space. Given that     Apple machines have been using EFI v1.10 services only for the longest time (the EFI v2.0 spec was     released in 2006, and Linux support for the newly introduced runtime services was added in 2011, but the     MacbookPro12,1 released in 2015 still claims to be EFI v1.10 only), let's avoid the EFI v2.0 ones on all     Apple x86 machines.
