From 8512670d3547d19a7e013e0b1e2e1916d8ee4000 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Mon, 4 Jul 2022 20:56:52 +0200 Subject: MIPS: math-emu: Use the bitmap API to allocate bitmaps Use bitmap_zalloc()/bitmap_free() instead of hand-writing them. It is less verbose and it improves the semantic.
