2017-08-04ACPICA: EFI/EDK2: Cleanup to enable /WX for MSVC buildsLv Zheng1-3/+3
ACPICA commit a7c6d65a5dab20b1e191c197e09af337fc54b341 /WX turns warning into fatal erros for MSVC builds. We need /WX- during EDK2 porting to allow agile development. Now it is time to enable /WX and some explicit type conversion cleanups are required for enabling /WX. Lv Zheng.

2017-08-04ACPICA: CLib: Add short multiply/shift supportLv Zheng5-16/+228
ACPICA commit 01b8f5a2350b9cc329cd8402ac8faec36fc501f5 In order to build ACPICA EFI tools with EDK-II on Windows, 64-bit multiply/shift supports are also required to be implemented. Otherwise, MSVC complains: acpidump.lib(utstrtoul64.obj) : error LNK2001: unresolved external symbol __allmul acpidump.lib(uthex.obj) : error LNK2001: unresolved external symbol __aullshr Note: 1. This patch also splits _EDK2_EFI from _GNU_EFI as they might have different math64 supports. 2. Support of gcc math64 is not included in this patch. 3. Support of EDK2 arch independent math64 is done via linking to base_lib. This patch fixes this issue. Reported by Shao Ming, fixed by Lv Zheng. For Linux kernel, this patch is a functional no-op.

ACPICA commit cf27b3c98883d2a15d932016792fcb8272ace96d The following commit introduces definition of access width to ACPICA. Commit: 2bece49394872d36bbc5767fd643deac05920c55 Subject: ACPI: SPCR: Use access width to determine mmio usage Actually the access bit width can be calculated via access width.

ACPICA commit 8b14afac65d983610cc5387ede6d85ea5ee075be The following ACPI table contains an invalid target node within the Alias operator: definition_block ("", "SSDT", 1, "Bug", "BugTable", 0x00001000) { Scope (_SB) { Device (DEV0) { Name (_ADR, 1) Device (DEV1) { Alias (_ADR, _ADR) } } } } If an ACPI table contains such an invalid target node in an Alias operator, a segmentation fault will occur when the target node is dereferenced within acpi_ex_create_alias.

ACPICA commit 894e49ef22db354eb1685cdb6f5f991766351d3c acpisrc now has capability to convert both the followings: 1. Form 1: typedef struct/union foo { struct/union foo { .... --> ... } FOO; } 2. Form 2: typedef struct/union foo FOO; --> typedef struct/union foo foo; It becomes unable to handle the following: 3. Form3: typedef struct/union foo { /* comment */ ... } FOO; --> strut/union foo { /* comment */ ... }; As: 1. The purpose of acpisrc is to convert formatted code (ACPICA coding style) into linux coding style, 2. acpisrc is a very simple tool that doesn't fully handle C language. This commit changes the definitions side in order not to regress and we shall make "no comments in struct/union line" as a new ACPICA coding style rule. Lv Zheng.

2017-07-15random: suppress spammy warnings about unseeded randomnessTheodore Ts'o1-17/+39
Unfortunately, on some models of some architectures getting a fully seeded CRNG is extremely difficult, and so this can result in dmesg getting spammed for a surprisingly long time. This is really bad from a security perspective, and so architecture maintainers really need to do what they can to get the CRNG seeded sooner after the system is booted. However, users can't do anything actionble to address this, and spamming the kernel messages log will only just annoy people. For developers who want to work on improving this situation, CONFIG_WARN_UNSEEDED_RANDOM has been renamed to CONFIG_WARN_ALL_UNSEEDED_RANDOM. By default the kernel will always print the first use of unseeded randomness. This way, hopefully the security obsessed will be happy that there is _some_ indication when the kernel boots there may be a potential issue with that architecture or subarchitecture. To see all uses of unseeded randomness, developers can enable CONFIG_WARN_ALL_UNSEEDED_RANDOM. Signed-off-by: Theodore Ts'o <tytso@mit.edu>

git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux Pull thermal management updates from Zhang Rui: - Improve thermal cpu_cooling interaction with cpufreq core. The cpu_cooling driver is designed to use CPU frequency scaling to avoid high thermal states for a platform. But it wasn't glued really well with cpufreq core. For example clipped-cpus is copied from the policy structure and its much better to use the policy->cpus (or related_cpus) fields directly as they may have got updated. Not that things were broken before this series, but they can be optimized a bit more. This series tries to improve interactions between cpufreq core and cpu_cooling driver and does some fixes/cleanups to the cpu_cooling driver.

The existing code gives an incorrect pointer value. The buffer pointer 'buf' was of type unsigned short *, and 'count' was a number in bytes. A cast of buf should have been used. However, instead of casting, just change the code to use u32 pointers.

2017-07-13mmc: block: Prevent new req entering queue after its cleanupGrzegorz Sluja1-0/+1
The commit 304419d8a7e9 ("mmc: core: Allocate per-request data using the block layer core"), refactored the mechanism of queue handling, but also made mmc_init_request() to be called after mmc_cleanup_queue(). This triggers a null pointer dereference: [ 683.123791] BUG: unable to handle kernel NULL pointer dereference at (null) [ 683.123801] IP: mmc_init_request+0x2c/0xf0 [mmc_block] ...
