WebFor early MIPS models lacking ll/sc atomics or the rdhwr TLS register, kernel emulation of these features is mandatory; this is standard on Linux.

WebFor rdhwr accessing the SYNCI_Step hardware register, this means using a mask that preserves the SPECIAL3, RDHWR, s and blank regions, ignoring the target register value t because it will change according to specific circumstances.

The Lexra LX5280 CPU [1] [2] implements the MIPS-I ISA, without unaligned load/store instructions (lwl, lwr, swl, swr). The programming model of this CPU is very similar. to the R3000 programming model, with a few differences. The Realtek RTL8186 SoC has this CPU, so this patch is required. for future RTL8186 SoC support.
