The dsi_irq_stats structure is a little too big to fit on the stack of a 32-bit task, depending on the specific gcc options: fbdev/omap2/omapfb/dss/dsi.c: In function 'dsi_dump_dsidev_irqs': fbdev/omap2/omapfb/dss/dsi.c:1621:1: error: the frame size of 1064 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Since this is only a debugfs file, performance is not critical, so just dynamically allocate it, and print an error message in there in place of a failure code when the allocation fails.

syzbot is reporting hung task at do_user_addr_fault() [1], for there is a silent deadlock between PG_locked bit and ni_lock lock. Since filemap_update_page() calls filemap_read_folio() after calling folio_trylock() which will set PG_locked bit, ntfs_truncate() must not call truncate_setsize() which will wait for PG_locked bit to be cleared when holding ni_lock lock.

If v4 READDIR operation hits a mountpoint and gets back an error, then it will include that entry in the reply and set RDATTR_ERROR for it to the error. That's fine for "normal" exported filesystems, but on the v4root, we need to be more careful to only expose the existence of dentries that lead to exports. If the mountd upcall times out while checking to see whether a mountpoint on the v4root is exported, then we have no recourse other than to fail the whole operation.

Commit 62d89a7d ("video: fbdev: matroxfb: set maxvram of vbG200eW to the same as vbG200 to avoid black screen") accidently decreases the maximum memory size for the Matrox G200eW (102b:0532) from 8 MB to 1 MB by missing one zero. This caused the driver initialization to fail with the messages below, as the minimum required VRAM size is 2 MB: [ 9.436420] matroxfb: Matrox MGA-G200eW (PCI) detected [ 9.444502] matroxfb: cannot determine memory size [ 9.449316] matroxfb: probe of 0000:0a:03.0 failed with error -1 So, add the missing 0 to make it the intended 16 MB. Successfully tested on the Dell PowerEdge R910/0KYD3D, BIOS 2.10.0 08/29/2013, that the warning is gone. While at it, add a leading 0 to the maxdisplayable entry, so it’s aligned properly. The value could probably also be increased from 8 MB to 16 MB, as the G200 uses the same values, but I have not checked any datasheet. Note, matroxfb is obsolete and superseded by the maintained DRM driver mga200, which is used by default on most systems where both drivers are available. Therefore, on most systems it was only a cosmetic issue.

Starting from ICL, the default for MIPI GPIO sequences seems to be using native GPIOs i.e. GPIOs available in the GPU. These native GPIOs reuse many pins that quite frankly seem scary to poke based on the VBT sequences. We pretty much have to trust that the board is configured such that the relevant HPD, PP_CONTROL and GPIO bits aren't used for anything else. MIPI sequence v4 also adds a flag to fall back to non-native sequences. v5: - Wrap SHOTPLUG_CTL_DDI modification in spin_lock() in icp_irq_handler() too (Ville) - References instead of Closes issue 6131 because this does not fix everything v4: - Wrap SHOTPLUG_CTL_DDI modification in spin_lock_irq() (Ville) v3: - Fix -Wbitwise-conditional-parentheses (kernel test robot <lkp@intel.com>) v2: - Fix HPD pin output set (impacts GPIOs 0 and 5) - Fix GPIO data output direction set (impacts GPIOs 4 and 9) - Reduce register accesses to single intel_de_rwm() References: https://gitlab.freedesktop.org/drm/intel/-/issues/6131 Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Guoqing Jiang reports that openSUSE cannot compile the kernel rpm due to "BuildRequires: elfutils-libelf-devel" added by commit 8818039f ("kbuild: add ability to make source rpm buildable using koji"). The relevant package name in openSUSE is libelf-devel. Add it as an alternative package. BTW, if it is impossible to solve the build requirement, the final resort would be: $ make RPMOPTS=--nodeps rpm-pkg This passes --nodeps to the rpmbuild command so it will not verify build dependencies. This is useful to test rpm builds on non-rpm system. On Debian/Ubuntu, for example, you can install rpmbuild by 'apt-get install rpm'. NOTE1: Likewise, it is possible to bypass the build dependency check for debian package builds: $ make DPKG_FLAGS=-d deb-pkg NOTE2: The 'or' operator is supported since RPM 4.13. So, old distros such as CentOS 7 will break. I suggest installing newer rpmbuild in such cases.

commit 3d57e1b7 ("kbuild: refactor the prerequisites of the modpost rule") moved 'vmlinux.o' inside modpost-args, possibly before some of the other options. However, getopt() in musl libc follows POSIX and stops looking for options upon reaching the first non-option argument. As a result, the '-T' option is misinterpreted as a positional argument, and the build fails: make -f ./scripts/Makefile.modpost scripts/mod/modpost -E -o Module.symvers vmlinux.o -T modules.order -T: No such file or directory make[1]: *** [scripts/Makefile.modpost:137: Module.symvers] Error 1 make: *** [Makefile:1960: modpost] Error 2 The fix is to move all options before 'vmlinux.o' in modpost-args.

Previously, *.rpm files were created under $HOME/rpmbuild/, but since commit 8818039f ("kbuild: add ability to make source rpm buildable using koji"), srcrpm-pkg creates the source rpm in the kernel tree because it sets '_srcrpmdir'. Signed-off-by:

Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux since commit 994b7ac1 ("arm64: remove special treatment for the link order of head.o"). The issue is that the type of .notes section, which contains the BuildID, changed from NOTES to PROGBITS. Ard Biesheuvel figured out that whichever object gets linked first gets to decide the type of a section. The PROGBITS type is the result of the compiler emitting .note.GNU-stack as PROGBITS rather than NOTE. While Ard provided a fix for arm64, I want to fix this globally because the same issue is happening on riscv since commit 2348e6bf ("riscv: remove special treatment for the link order of head.o"). This problem will happen in general for other architectures if they start to drop unneeded entries from scripts/head-object-list.txt. Discard .note.GNU-stack in include/asm-generic/vmlinux.lds.h.

In the case where a firmware file is too large (e.g. someone downloaded a web page ASCII dump from github...), the firmware object is released but the pointer is not zerod. If no other firmware file was found then release would be called again leading to a double kfree. Also, the size check was only being applied to the initial firmware load not any of the subsequent attempts. So move the check into a wrapper that is used for all loads.
