Subject: target/loongarch: Use loongarch_tlb_search_cb in helper_invtlb_page_asid_or_g
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=96e654cf3e6e03d61de447ad7117f53ed2bff998;p=thirdparty%2Fqemu.git

target/loongarch: Use loongarch_tlb_search_cb in helper_invtlb_page_asid_or_g

With function helper_invtlb_page_asid_or_g(), currently it is to
search TLB entry one by one. Instead STLB can be searched at first
with hash method, and then search MTLB with one by one method.

Here common API loongarch_tlb_search_cb() is used in function
helper_invtlb_page_asid_or_g().
