File _service:tar_scm:linux-headers-Update-to-Linux-v6.7-rc5.patch of Package qemu
From 9904eb7d4559baca2da713346cd505a80af7e776 Mon Sep 17 00:00:00 2001 From: Daniel Henrique Barboza <dbarboza@ventanamicro.com> Date: Mon, 18 Dec 2023 17:43:18 -0300 Subject: [PATCH] linux-headers: Update to Linux v6.7-rc5 We'll add a new RISC-V linux-header file, but first let's update all headers. Headers for 'asm-loongarch' were added in this update.
