From fa0809bb2a23871b686a7ae8a4cbd146020754d8 Mon Sep 17 00:00:00 2001 From: Varada Pavani Date: Tue, 25 Feb 2025 18:49:18 +0530 Subject: [PATCH 1/5] clk: samsung: update PLL locktime for PLL142XX used on FSD platform commit 53517a70873c7a91675f7244768aad5006cc45de upstream. Currently PLL142XX locktime is 270. As per spec, it should be 150. Hence update PLL142XX controller locktime to 150.

The internal microphone on the Lenovo ThinkPad E16 model requires a quirk entry to work properly. This was fixed in a previous patch (linked below), but depending on the specific variant of the model, the product name may be "21M5" or "21M6". The following patch fixed this issue for the 21M5 variant: https://lore.kernel.org/all/20240725065442.9293-1-tiwai@suse.de/ This patch adds support for the microphone on the 21M6 variant.

The kernel cannot currently self-parse BTF containing Rust debug information. pahole uses the language of the CU to determine whether to filter out debug information when generating the BTF. When LTO is enabled, Rust code can cross CU boundaries, resulting in Rust debug information in CUs labeled as C. This results in a system which cannot parse its own BTF.

The memory region is removed from the kernel page tables and only the page tables of the processes holding the file descriptor map the corresponding physical memory. (Thus, the pages in the region can't be accessed by the kernel itself, so that, for example, pointers to the region can't be passed to system calls.) We need to handle this special case gracefully in build ID fetching code. Return -EFAULT whenever secretmem file is passed to build_id_parse() family of APIs.
