commit 33092fb3af51deb80849e90a17bada44bbcde6b3 upstream. The UC-257 is a serial + LPT card, so remove it from this driver. A patch has been submitted to add it to parport_serial instead. Additionaly, the UC-431 does not use this card ID, only the UC-420 does. The 431 is a 3-port card and there is no generic 3-port configuration available, so remove reference to it from this driver.

2023-11-08ata: ahci: fix enum constants for gcc-13Arnd Bergmann1-115/+117
commit f07788079f515ca4a681c5f595bdad19cfbd7b1d upstream. gcc-13 slightly changes the type of constant expressions that are defined in an enum, which triggers a compile time sanity check in libata: linux/drivers/ata/libahci.c: In function 'ahci_led_store': linux/include/linux/compiler_types.h:357:45: error: call to '__compiletime_assert_302' declared with attribute error: BUILD_BUG_ON failed: sizeof(_s) > sizeof(long) 357 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__) The new behavior is that sizeof() returns the same value for the constant as it does for the enum type, which is generally more sensible and consistent. The problem in libata is that it contains a single enum definition for lots of unrelated constants, some of which are large positive (unsigned) integers like 0xffffffff, while others like (1<<31) are interpreted as negative integers, and this forces the enum type to become 64 bit wide even though most constants would still fit into a signed 32-bit 'int'. Fix this by changing the entire enum definition to use BIT(x) in place of (1<<x), which results in all values being seen as 'unsigned' and fitting into an unsigned 32-bit type.

2023-11-08platform/x86: asus-wmi: Change ASUS_WMI_BRN_DOWN code from 0x20 to 0x2eHans de Goede1-1/+1
[ Upstream commit f37cc2fc277b371fc491890afb7d8a26e36bb3a1 ] Older Asus laptops change the backlight level themselves and then send WMI events with different codes for different backlight levels. The asus-wmi.c code maps the entire range of codes reported on brightness down keypresses to an internal ASUS_WMI_BRN_DOWN code: define NOTIFY_BRNUP_MIN 0x11 define NOTIFY_BRNUP_MAX 0x1f define NOTIFY_BRNDOWN_MIN 0x20 define NOTIFY_BRNDOWN_MAX 0x2e if (code >= NOTIFY_BRNUP_MIN && code <= NOTIFY_BRNUP_MAX) code = ASUS_WMI_BRN_UP; else if (code >= NOTIFY_BRNDOWN_MIN && code <= NOTIFY_BRNDOWN_MAX) code = ASUS_WMI_BRN_DOWN; Before this commit all the NOTIFY_BRNDOWN_MIN - NOTIFY_BRNDOWN_MAX aka 0x20 - 0x2e events were mapped to 0x20. This mapping is causing issues on new laptop models which actually send 0x2b events for printscreen presses and 0x2c events for capslock presses, which get translated into spurious brightness-down presses. The plan is disable the 0x11-0x2e special mapping on laptops where asus-wmi does not register a backlight-device to avoid the spurious brightness-down keypresses. New laptops always send 0x2e for brightness-down presses, change the special internal ASUS_WMI_BRN_DOWN value from 0x20 to 0x2e to match this in preparation for fixing the spurious brightness-down presses. This change does not have any functional impact since all of 0x20 - 0x2e is mapped to ASUS_WMI_BRN_DOWN first and only then checked against the keymap code and the new 0x2e value is still in the 0x20 - 0x2e range.

2023-11-08fbdev: atyfb: only use ioremap_uc() on i386 and ia64Arnd Bergmann1-0/+4
[ Upstream commit c1a8d1d0edb71dec15c9649cb56866c71c1ecd9e ] ioremap_uc() is only meaningful on old x86-32 systems with the PAT extension, and on ia64 with its slightly unconventional ioremap() behavior, everywhere else this is the same as ioremap() anyway. Change the only driver that still references ioremap_uc() to only do so on x86-32/ia64 in order to allow removing that interface at some point in the future for the other architectures. On some architectures, ioremap_uc() just returns NULL, changing the driver to call ioremap() means that they now have a chance of working correctly.

2023-11-08Input: synaptics-rmi4 - handle reset delay when using SMBus trsnsportDmitry Torokhov2-22/+29
[ Upstream commit 5030b2fe6aab37fe42d14f31842ea38be7c55c57 ] Touch controllers need some time after receiving reset command for the firmware to finish re-initializing and be ready to respond to commands from the host. The driver already had handling for the post-reset delay for I2C and SPI transports, this change adds the handling to SMBus-connected devices. SMBus devices are peculiar because they implement legacy PS/2 compatibility mode, so reset is actually issued by psmouse driver on the associated serio port, after which the control is passed to the RMI4 driver with SMBus companion device. Note that originally the delay was added to psmouse driver in 92e24e0e57f7 ("Input: psmouse - add delay when deactivating for SMBus mode"), but that resulted in an unwanted delay in "fast" reconnect handler for the serio port, so it was decided to revert the patch and have the delay being handled in the RMI4 driver, similar to the other transports.

[ Upstream commit 80f39e1c27ba9e5a1ea7e68e21c569c9d8e46062 ] In the initial boot stage the integrated keyboard of Fujitsu Lifebook E5411 refuses to work and it's not possible to type for example a dm-crypt passphrase without the help of an external keyboard. i8042.nomux kernel parameter resolves this issue but using that a PS/2 mouse is detected. This input device is unused even when the i2c-hid-acpi kernel module is blacklisted making the integrated ELAN touchpad (04F3:308A) not working at all. Since the integrated touchpad is managed by the i2c_designware input driver in the Linux kernel and you can't find a PS/2 mouse port on the computer I think it's safe to not use the PS/2 mouse port at all.

[ Upstream commit 41bae58df411f9accf01ea660730649b2fab1dab ] asoc_simple_probe() is used for both "DT probe" (A) and "platform probe" (B). It uses "goto err" when error case, but it is not needed for "platform probe" case (B). Thus it is using "return" directly there. static int asoc_simple_probe(...) { ^ if (...) { | ...

But (D) will do nothing for (B) case. Because of these behavior, current code itself is not wrong, but is confusable, and more, static analyzing tool will warning on (B) part (should use goto err). To avoid static analyzing tool warning, this patch uses "goto err" on (B) part.

commit 7e09ac27f43b382f5fe9bb7c7f4c465ece1f8a23 upstream. Commit in Fixes added the "NOLOAD" attribute to the .brk section as a "failsafe" measure. Unfortunately, this leads to the linker no longer covering the .brk section in a program header, resulting in the kernel loader not knowing that the memory for the .brk section must be reserved. This has led to crashes when loading the kernel as PV dom0 under Xen, but other scenarios could be hit by the same problem (e.g. in case an uncompressed kernel is used and the initrd is placed directly behind it). So drop the "NOLOAD" attribute. This has been verified to correctly cover the .brk section by a program header of the resulting ELF file.

commit 42cd402b8fd4672b692400fe5f9eecd55d2794ac upstream. The driver_override field from platform driver should not be initialized from static memory (string literal) because the core later kfree() it, for example when driver_override is set via sysfs. Use dedicated helper to set driver_override properly.

2023-11-08driver: platform: Add helper for safer setting of driver_overrideKrzysztof Kozlowski4-25/+80
commit 6c2f421174273de8f83cde4286d1c076d43a2d35 upstream. Several core drivers and buses expect that driver_override is a dynamically allocated memory thus later they can kfree() it. However such assumption is not documented, there were in the past and there are already users setting it to a string literal. This leads to kfree() of static memory during device release (e.g. in error paths or during unbind): kernel BUG at ../mm/slub.c:3960! Internal error: Oops - BUG: 0 [#1] PREEMPT SMP ARM ...

2023-11-08x86/mm: Fix RESERVE_BRK() for older binutilsJosh Poimboeuf2-19/+23
commit e32683c6f7d22ba624e0bfc58b02cf3348bdca63 upstream. With binutils 2.26, RESERVE_BRK() causes a build failure: /tmp/ccnGOKZ5.s: Assembler messages: /tmp/ccnGOKZ5.s:98: Error: missing ')' /tmp/ccnGOKZ5.s:98: Error: missing ')' /tmp/ccnGOKZ5.s:98: Error: missing ')' /tmp/ccnGOKZ5.s:98: Error: junk at end of line, first unrecognized character is `U' The problem is this line: RESERVE_BRK(early_pgt_alloc, INIT_PGT_BUF_SIZE) Specifically, the INIT_PGT_BUF_SIZE macro which (via PAGE_SIZE's use _AC()) has a "1UL", which makes older versions of the assembler unhappy. Unfortunately the _AC() macro doesn't work for inline asm. Inline asm was only needed here to convince the toolchain to add the STT_NOBITS flag. However, if a C variable is placed in a section whose name is prefixed with ".bss", GCC and Clang automatically set STT_NOBITS. In fact, ".bss..page_aligned" already relies on this trick. So fix the build failure (and simplify the macro) by allocating the variable in C. Also, add NOLOAD to the ".brk" output section clause in the linker script. This is a failsafe in case the ".bss" prefix magic trick ever stops working somehow. If there's a section type mismatch, the GNU linker will force the ".brk" output section to be STT_NOBITS. The LLVM linker will fail with a "section type mismatch" error. Note this also changes the name of the variable from .brk.##name to __brk_##name. The variable names aren't actually used anywhere, so it's harmless.

commit a1e2c031ec3949b8c039b739c0b5bf9c30007b00 upstream. RESERVE_BRK() reserves data in the .brk_reservation section. The data is initialized to zero, like BSS, so the macro specifies 'nobits' to prevent the data from taking up space in the vmlinux binary. The only way to get the compiler to do that (without putting the variable in .bss proper) is to use inline asm. The macro also has a hack which encloses the inline asm in a discarded function, which allows the size to be passed (global inline asm doesn't allow inputs). Remove the need for the discarded function hack by just stringifying the size rather than supplying it as an input to the inline asm.

2023-11-08arm64: fix a concurrency issue in emulation_proc_handler()Jinjie Ruan1-2/+4
In linux-6.1, the related code is refactored in commit 124c49b1b5d9 ("arm64: armv8_deprecated: rework deprected instruction handling") and this issue was incidentally fixed. I have adapted the patch set to linux stable 5.10. However, 4.19 and 5.10 are too different and the patch set is hard to adapt to 4.19. This patch is to solve the problem of repeated addition of linked lists described below with few changes. How to reproduce: CONFIG_ARMV8_DEPRECATED=y, CONFIG_SWP_EMULATION=y, and CONFIG_DEBUG_LIST=y, then launch two shell executions: #!/bin/bash while [ 1 ]; do echo 1 > /proc/sys/abi/swp done or "echo 1 > /proc/sys/abi/swp" and then aunch two shell executions: #!/bin/bash while [ 1 ]; do echo 0 > /proc/sys/abi/swp done In emulation_proc_handler(), read and write operations are performed on insn->current_mode. In the concurrency scenario, mutex only protects writing insn->current_mode, and not protects the read. Suppose there are two concurrent tasks, task1 updates insn->current_mode to INSN_EMULATE in the critical section, the prev_mode of task2 is still the old data INSN_UNDEF of insn->current_mode. As a result, two tasks call update_insn_emulation_mode twice with prev_mode = INSN_UNDEF and current_mode = INSN_EMULATE, then call register_emulation_hooks twice, resulting in a list_add double problem. After applying this patch, the following list add or list del double warnings never occur.

2023-11-08x86/i8259: Skip probing when ACPI/MADT advertises PCAT compatibilityThomas Gleixner3-8/+35
commit 128b0c9781c9f2651bea163cb85e52a6c7be0f9e upstream. David and a few others reported that on certain newer systems some legacy interrupts fail to work correctly. Debugging revealed that the BIOS of these systems leaves the legacy PIC in uninitialized state which makes the PIC detection fail and the kernel switches to a dummy implementation. Unfortunately this fallback causes quite some code to fail as it depends on checks for the number of legacy PIC interrupts or the availability of the real PIC. In theory there is no reason to use the PIC on any modern system when IO/APIC is available, but the dependencies on the related checks cannot be resolved trivially and on short notice. This needs lots of analysis and rework. The PIC detection has been added to avoid quirky checks and force selection of the dummy implementation all over the place, especially in VM guest scenarios. So it's not an option to revert the relevant commit as that would break a lot of other scenarios. One solution would be to try to initialize the PIC on detection fail and retry the detection, but that puts the burden on everything which does not have a PIC. Fortunately the ACPI/MADT table header has a flag field, which advertises in bit 0 that the system is PCAT compatible, which means it has a legacy 8259 PIC. Evaluate that bit and if set avoid the detection routine and keep the real PIC installed, which then gets initialized (for nothing) and makes the rest of the code with all the dependencies work again.

2023-11-08i2c: stm32f7: Fix PEC handling in case of SMBUS transfersAlain Volmat1-3/+6
commit c896ff2dd8f30a6b0a922c83a96f6d43f05f0e92 upstream. In case of SMBUS byte read with PEC enabled, the whole transfer is split into two commands. A first write command, followed by a read command. The write command does not have any PEC byte and a PEC byte is appended at the end of the read command. (cf Read byte protocol with PEC in SMBUS specification) Within the STM32 I2C controller, handling (either sending or receiving) of the PEC byte is done via the PECBYTE bit in register CR2. Currently, the PECBYTE is set at the beginning of a transfer, which lead to sending a PEC byte at the end of the write command (hence losing the real last byte), and also does not check the PEC byte received during the read command. This patch corrects the function stm32f7_i2c_smbus_xfer_msg in order to only set the PECBYTE during the read command.

2023-11-08i2c: muxes: i2c-demux-pinctrl: Use of_get_i2c_adapter_by_node()Herve Codina1-1/+1
commit 0fb118de5003028ad092a4e66fc6d07b86c3bc94 upstream. i2c-demux-pinctrl uses the pair of_find_i2c_adapter_by_node() / i2c_put_adapter(). These pair alone is not correct to properly lock the I2C parent adapter. Indeed, i2c_put_adapter() decrements the module refcount while of_find_i2c_adapter_by_node() does not increment it. This leads to an underflow of the parent module refcount. Use the dedicated function, of_get_i2c_adapter_by_node(), to handle correctly the module refcount.
