LoongArch: Add Loongson Binary Translation (LBT) extension support
Loongson Binary Translation (LBT) is used to accelerate binary translation, which contains 4 scratch registers (scr0 to scr3), x86/ARM eflags (eflags) and x87 fpu stack pointer (ftop).
This patch support kernel to save/restore these registers, handle the LBT exception and maintain sigcontext.

LoongArch: Define symbol 'fault' as a local label in fpu.S
The initial aim is to silence the following objtool warnings:
arch/loongarch/kernel/fpu.o: warning: objtool: _save_fp_context() falls through to next function fault() arch/loongarch/kernel/fpu.o: warning: objtool: _restore_fp_context() falls through to next function fault() arch/loongarch/kernel/fpu.o: warning: objtool: _save_lsx_context() falls through to next function fault() arch/loongarch/kernel/fpu.o: warning: objtool: _restore_lsx_context() falls through to next function fault() arch/loongarch/kernel/fpu.o: warning: objtool: _save_lasx_context() falls through to next function fault() arch/loongarch/kernel/fpu.o: warning: objtool: _restore_lasx_context() falls through to next function fault()
Currently, SYM_FUNC_START()/SYM_FUNC_END() defines the symbol 'fault' as SYM_T_FUNC which is STT_FUNC, the objtool warnings are generated through the following code:
tools/objtool/include/objtool/check.h:
static inline struct symbol *insn_func(struct instruction *insn) { struct symbol *sym = insn->sym;
if (sym && sym->type != STT_FUNC) sym = NULL;
return sym; }
tools/objtool/check.c:
static int validate_branch(struct objtool_file *file, struct symbol *func, struct instruction *insn, struct insn_state state) { ... if (func && insn_func(insn) && func != insn_func(insn)->pfunc) { ... WARN("%s() falls through to next function %s()", func->name, insn_func(insn)->name); return 1; } ... }
We can see that the fixup can be a local label in the following code:
arch/loongarch/include/asm/asm-extable.h: .pushsection __ex_table, "a"; \ .balign 4; \ .long ((insn) - .); \ .long ((fixup) - .); \ .short (type); \ .short (data); \ .popsection;
.macro _asm_extable, insn, fixup __ASM_EXTABLE_RAW(\insn, \fixup, EX_TYPE_FIXUP, 0) .endm
Like arch/loongarch/lib/*.S, just define the symbol 'fault' as a local label in fpu.S.
Before:
$ readelf -s arch/loongarch/kernel/fpu.o | awk -F: /fault/'{print $2}' 000000000000053c 8 FUNC GLOBAL DEFAULT 1 fault
After:
$ readelf -s arch/loongarch/kernel/fpu.o | awk -F: /fault/'{print $2}' 000000000000053c 0 NOTYPE LOCAL DEFAULT 1 .L_fpu_fault

LoongArch: Add vector extensions support
Add LoongArch's vector extensions support, which including 128bit LSX (i.e., Loongson SIMD eXtension) and 256bit LASX (i.e., Loongson Advanced SIMD eXtension).
Linux kernel doesn't use vector itself, it only handle exceptions and context save/restore. So it only needs a subset of these instructions:
* Vector load/store: vld vst vldx vstx xvld xvst xvldx xvstx * 8bit-elements move: vpickve2gr.b xvpickve2gr.b vinsgr2vr.b xvinsgr2vr.b * 16bit-elements move: vpickve2gr.h xvpickve2gr.h vinsgr2vr.h xvinsgr2vr.h * 32bit-elements move: vpickve2gr.w xvpickve2gr.w vinsgr2vr.w xvinsgr2vr.w * 64bit-elements move: vpickve2gr.d xvpickve2gr.d vinsgr2vr.d xvinsgr2vr.d * Elements permute: vpermi.w vpermi.d xvpermi.w xvpermi.d xvpermi.q
Introduce AS_HAS_LSX_EXTENSION and AS_HAS_LASX_EXTENSION to avoid non- vector toolchains complains unsupported instructions.
