Liang Li e67a807f3d x86: Fix 'reservetop=' functionality ... When specifying the 'reservetop=0xbadc0de' kernel parameter, the kernel will stop booting due to a early_ioremap bug that relates to commit 8827247ff. The root cause of boot failure problem is the value of 'slot_virt[i]' was initialized in setup_arch->early_ioremap_init(). But later in setup_arch, the function 'parse_early_param' will modify 'FIXADDR_TOP' when 'reservetop=0xbadc0de' being specified. The simplest fix might be use __fix_to_virt(idx0) to get updated value of 'FIXADDR_TOP' in '__early_ioremap' instead of reference old value from slot_virt[slot] directly. Changelog since v0: -v1: When reservetop being handled then FIXADDR_TOP get adjusted, Hence check prev_map then re-initialize slot_virt and PMD based on new FIXADDR_TOP. -v2: place fixup_early_ioremap hence call early_ioremap_init in reserve_top_address to re-initialize slot_virt and corresponding PMD when parse_reservertop -v3: move fixup_early_ioremap out of reserve_top_address to make sure other clients of reserve_top_address like xen/lguest won't broken Signed-off-by: Liang Li <liang.li@windriver.com> Tested-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Acked-by: Yinghai Lu <yinghai@kernel.org> Acked-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Cc: Wang Chen <wangchen@cn.fujitsu.com> Cc: "H.
