From 596516d3301ef7b6594dc5d24bc8fd4461279437 Mon Sep 17 00:00:00 2001 From: Sughosh Ganu Date: Tue, 15 Oct 2024 21:07:15 +0530 Subject: [PATCH] lmb: remove call to efi_lmb_reserve() The EFI memory allocations are now being done through the LMB module. With this change, there is no need to get the EFI memory map and set aside EFI allocated memory.
