==== KernelFlags ====
Kernel reads this when setting up memory-related code. If bit0 is set, it will memset various allocated memory-regions with 0x58, 0x59, 0x5A ('X', 'Y', 'Z') instead of zero. This allows Nintendo devs to find uninitialized memory bugs. If bit17-16 is 0b01, the kernel assumes 6GB of DRAM instead of 4GB.

Bit 0 is a boolean determining whether kernel should it will memset various allocated memory-regions with 0x58, 0x59, 0x5A ('X', 'Y', 'Z') instead of zero. This allows Nintendo devs to find uninitialized memory bugs.
Bit 1 is a boolean determining whether kernel should forcefully enable usermode exception handlers (when false, only data aborts/prefetch aborts that occur when the faulting address is in a readable region with MemoryType_CodeStatic will trigger usermode exception handlers).
Bit 2 is a boolean determining whether kernel should enable usermode access to the Performance Monitors (whether PMUSERENR_EL0 should be 1 or 0).
Bits 8-15 are a boolean determining whether kernel should call smcPanic on error instead of infinite-looping.
Bits 16-17 determine how much memory is available. 00/03 = 4 GB, 01 = 6 GB, 02 = 8 GB.
