On some Cherry Trail devices the second PWM controller uses 80862289 as ACPI _HID, rather then using 80862288 as is done for both controllers on most models. Add the missing 80862289 ACPI _HID, note this uses its own lpss_device_desc, without ".setup = bsw_pwm_setup" so that the pwm_lookup is not added for it. On devices where both controllers use the 80862288 _HID bsw_pwm_setup() does a UID check to avoid registering the lookup for the second controller but that will not work here. Adding the missing id fixes the second PWM controller no longer working after the entire LPSS1 island has been in D3 at least once, which causes the contents of the LPSS private registers to get lost. Adding the _HID makes acpi_lpss restore these when the controller moves from D3 to D0.

Currently, acpi_device_remove_notify_handler() may return while the notify handler being removed is still running which may allow the module holding that handler to be torn down prematurely.

Commit 05e96e96 ("kbuild: use git-archive for source package creation") split the compression as a separate step to factor out the common build rules. With the previous commit, we got back to the situation where source tarballs are compressed on-the-fly. There is no reason to keep the separate compression rules. Generate the comressed tar packages directly. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nathan Chancellor <nathan@kernel.org>

Masahiro Yamada authored
Since commit 05e96e96 ("kbuild: use git-archive for source package creation"), a source tarball is created in two steps; create *.tar file then compress it. I split the compression as a separate rule because I just thought 'git archive' supported only gzip. For other compression algorithms, I could pipe the two commands: $ git archive HEAD | xz > linux.tar.xz I read git-archive(1) carefully, and I realized GIT had provided a more elegant way: $ git -c tar.tar.xz.command=xz archive -o linux.tar.xz HEAD This commit uses 'tar.tar.*.command' configuration to specify the compression backend so we can compress a source tarball on-the-fly. GIT commit 767cf4579f0e ("archive: implement configurable tar filters") is more than a decade old, so it should be available on almost all build environments.

Forwarding variadic argument lists can't be done by passing a va_list to a function with signature foo(...) (as panic() has). It ends up interpreting the va_list itself as a single argument instead of iterating it. printf() happily accepts it of course, leading to corrupt output. Convert panic_show_mem() to a macro to allow forwarding the arguments. The function is trivial enough that it's easier than trying to introduce a vpanic() variant.

Similar to commit 4c9d410f ("initramfs: Check timestamp to prevent broken cpio archive"), except asserts that the timestamp is non-negative. This can happen when the KBUILD_BUILD_TIMESTAMP is a value before UNIX epoch, which may be set when making reproducible builds that don't want to look like they use a valid date. While support for dates before 1970 might not be supported, this is more about preventing undetected CPIO corruption. The printf's use a minimum length format specifier, and will happily make the field longer than 8 characters if they need to.

So far io_req_complete_post() only covers DEFER_TASKRUN by completing request via task work when the request is completed from IOWQ. However, uring command could be completed from any context, and if io uring is setup with DEFER_TASKRUN, the command is required to be completed from current context, otherwise wait on IORING_ENTER_GETEVENTS can't be wakeup, and may hang forever. The issue can be observed on removing ublk device, but turns out it is one generic issue for uring command & DEFER_TASKRUN, so solve it in io_uring core code.

riscv establishes 2 virtual mappings: - early_pg_dir maps the kernel which allows to discover the system memory - swapper_pg_dir installs the final mapping (linear mapping included) We used to map the dtb in early_pg_dir using DTB_EARLY_BASE_VA, and this mapping was not carried over in swapper_pg_dir. It happens that early_init_fdt_scan_reserved_mem() must be called before swapper_pg_dir is setup otherwise we could allocate reserved memory defined in the dtb. And this function initializes reserved_mem variable with addresses that lie in the early_pg_dir dtb mapping: when those addresses are reused with swapper_pg_dir, this mapping does not exist and then we trap. The previous "fix" was incorrect as early_init_fdt_scan_reserved_mem() must be called before swapper_pg_dir is set up otherwise we could allocate in reserved memory defined in the dtb. So move the dtb mapping in the fixmap region which is established in early_pg_dir and handed over to swapper_pg_dir.
