Commit 83919535 ("mm/shuffle: remove dynamic reconfiguration") removed the dynamic reconfiguration capabilities from the shuffle page allocator. This means that, now, we don't have any perspective of an "autodetection of memory-side-cache" that triggers the enablement of the shuffle page allocator. Therefore, let the documentation reflect that the only way to enable the shuffle page allocator is by setting `page_alloc.shuffle=1`. Signed-off-by:

sched_core_share_pid() copies the cookie to userspace with put_user(id, (u64 __user *)uaddr), expecting 64 bits of space. The "unsigned long" datatype that is documented in core-scheduling.rst however is only 32 bits large on 32 bit architectures. Document "unsigned long long" as the correct data type that is always 64bits large. This matches what the selftest cs_prctl_test.c has been doing all along.

Fedora and openSUSE has started deploying "variable font" [1] format Noto CJK fonts [2, 3]. "CJK" here stands for "Chinese, Japanese, and Korean". Unfortunately, XeTeX/XeLaTeX doesn't understand those fonts for historical reasons and builds of translations.pdf end up in errors if such fonts are present on the build host. To help developers work around the issue, add a script to check the presence of "variable font" Noto CJK fonts and to emit suggestions. The script is invoked in the error path of "make pdfdocs" so that the suggestions are made only when a PDF build actually fails. The first suggestion is to denylist those "variable font" files by activating a per-user and command-local fontconfig setting. For further info and backgrounds, please refer to the header comment of scripts/check-variable-font.sh newly added in this commit.

There are bunch of codes in driver like if (dma_set_mask_and_coherent(dev, DMA_BIT_MASK(64))) dma_set_mask_and_coherent(dev, DMA_BIT_MASK(32)) Actually it is wrong because if dma_set_mask_and_coherent(64) fails, dma_set_mask_and_coherent(32) will fail for the same reason. And dma_set_mask_and_coherent(64) never returns failure. According to the definition of dma_set_mask(), it indicates the width of address that device DMA can access. If it can access 64-bit address, it must access 32-bit address inherently. So only need set biggest address width. See below code fragment: dma_set_mask(mask) { mask = (dma_addr_t)mask; if (!dev->dma_mask || !dma_supported(dev, mask)) return -EIO; arch_dma_set_mask(dev, mask); *dev->dma_mask = mask; return 0; } dma_supported() will call dma_direct_supported or iommux's dma_supported call back function. int dma_direct_supported(struct device *dev, u64 mask) { u64 min_mask = (max_pfn - 1) << PAGE_SHIFT; /* * Because 32-bit DMA masks are so common we expect every architecture * to be able to satisfy them - either by not supporting more physical * memory, or by providing a ZONE_DMA32. If neither is the case, the * architecture needs to use an IOMMU instead of the direct mapping. */ if (mask >= DMA_BIT_MASK(32)) return 1; ... } The iommux's dma_supported() actually means iommu requires devices's minimized dma capability. An example: static int sba_dma_supported( struct device *dev, u64 mask)() { ... * check if mask is >= than the current max IO Virt Address * The max IO Virt address will *always* < 30 bits. */ return((int)(mask >= (ioc->ibase - 1 + (ioc->pdir_size / sizeof(u64) * IOVP_SIZE) ))); ... } 1 means supported. 0 means unsupported.

Pull x86 fixes from Thomas Gleixner: - Ensure that the encryption mask at boot is properly propagated on 5-level page tables, otherwise the PGD entry is incorrectly set to non-encrypted, which causes system crashes during boot. - Undo the deferred 5-level page table setup as it cannot work with memory encryption enabled. - Prevent inconsistent XFD state on CPU hotplug, where the MSR is reset to the default value but the cached variable is not, so subsequent comparisons might yield the wrong result and as a consequence the result prevents updating the MSR. - Register the local APIC address only once in the MPPARSE enumeration to prevent triggering the related WARN_ONs() in the APIC and topology code. - Handle the case where no APIC is found gracefully by registering a fake APIC in the topology code. That makes all related topology functions work correctly and does not affect the actual APIC driver code at all. - Don't evaluate logical IDs during early boot as the local APIC IDs are not yet enumerated and the invoked function returns an error code. Nothing requires the logical IDs before the final CPUID enumeration takes place, which happens after the enumeration. - Cure the fallout of the per CPU rework on UP which misplaced the copying of boot_cpu_data to per CPU data so that the final update to boot_cpu_data got lost which caused inconsistent state and boot crashes. - Use copy_from_kernel_nofault() in the kprobes setup as there is no guarantee that the address can be safely accessed. - Reorder struct members in struct saved_context to work around another kmemleak false positive - Remove the buggy code which tries to update the E820 kexec table for setup_data as that is never passed to the kexec kernel. - Update the resource control documentation to use the proper units. - Fix a Kconfig warning observed with tinyconfig * tag 'x86-urgent-2024-03-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/boot/64: Move 5-level paging global variable assignments back x86/boot/64: Apply encryption mask to 5-level pagetable update x86/cpu: Add model number for another Intel Arrow Lake mobile processor x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD Documentation/x86: Document that resctrl bandwidth control units are MiB x86/mpparse: Register APIC address only once x86/topology: Handle the !APIC case gracefully x86/topology: Don't evaluate logical IDs during early boot x86/cpu: Ensure that CPU info updates are propagated on UP kprobes/x86: Use copy_from_kernel_nofault() to read from unsafe address x86/pm: Work around false positive kmemleak report in msr_build_context() x86/kexec: Do not update E820 kexec table for setup_data x86/config: Fix warning for 'make ARCH=x86_64 tinyconfig'

Clearing BSS should only be done once, at the very beginning. efi_pe_entry() is the entrypoint from the firmware, which may not clear BSS and so it is done explicitly. However, efi_pe_entry() is also used as an entrypoint by the mixed mode startup code, in which case BSS will already have been cleared, and doing it again at this point will corrupt global variables holding the firmware's GDT/IDT and segment selectors. So make the memset() conditional on whether the EFI stub is running in native mode. Fixes: b3810c5a ("x86/efistub: Clear decompressor BSS in native EFI entrypoint") Signed-off-by:

Normally, the EFI stub calls into the EFI boot services using the stack that was live when the stub was entered. According to the UEFI spec, this stack needs to be at least 128k in size - this might seem large but all asynchronous processing and event handling in EFI runs from the same stack and so quite a lot of space may be used in practice. In mixed mode, the situation is a bit different: the bootloader calls the 32-bit EFI stub entry point, which calls the decompressor's 32-bit entry point, where the boot stack is set up, using a fixed allocation of 16k. This stack is still in use when the EFI stub is started in 64-bit mode, and so all calls back into the EFI firmware will be using the decompressor's limited boot stack. Due to the placement of the boot stack right after the boot heap, any stack overruns have gone unnoticed. However, commit 5c4feadb0011983b ("x86/decompressor: Move global symbol references to C code") moved the definition of the boot heap into C code, and now the boot stack is placed right at the base of BSS, where any overruns will corrupt the end of the .data section. While it would be possible to work around this by increasing the size of the boot stack, doing so would affect all x86 systems, and mixed mode systems are a tiny (and shrinking) fraction of the x86 installed base. So instead, record the firmware stack pointer value when entering from the 32-bit firmware, and switch to this stack every time a EFI boot service call is made.

Commit 63bed966 ("x86/startup_64: Defer assignment of 5-level paging global variables") moved assignment of 5-level global variables to later in the boot in order to avoid having to use RIP relative addressing in order to set them. However, when running with 5-level paging and SME active (mem_encrypt=on), the variables are needed as part of the page table setup needed to encrypt the kernel (using pgd_none(), p4d_offset(), etc.). Since the variables haven't been set, the page table manipulation is done as if 4-level paging is active, causing the system to crash on boot. While only a subset of the assignments that were moved need to be set early, move all of the assignments back into check_la57_support() so that these assignments aren't spread between two locations. Instead of just reverting the fix, this uses the new RIP_REL_REF() macro when assigning the variables.

When running with 5-level page tables, the kernel mapping PGD entry is updated to point to the P4D table. The assignment uses _PAGE_TABLE_NOENC, which, when SME is active (mem_encrypt=on), results in a page table entry without the encryption mask set, causing the system to crash on boot. Change the assignment to use _PAGE_TABLE instead of _PAGE_TABLE_NOENC so that the encryption mask is set for the PGD entry.

Commit 67236547 ("x86/fpu: Update XFD state where required") and commit 8bf26758 ("x86/fpu: Add XFD state to fpstate") introduced a per CPU variable xfd_state to keep the MSR_IA32_XFD value cached, in order to avoid unnecessary writes to the MSR. On CPU hotplug MSR_IA32_XFD is reset to the init_fpstate.xfd, which wipes out any stale state. But the per CPU cached xfd value is not reset, which brings them out of sync. As a consequence a subsequent xfd_update_state() might fail to update the MSR which in turn can result in XRSTOR raising a #NM in kernel space, which crashes the kernel. To fix this, introduce xfd_set_state() to write xfd_state together with MSR_IA32_XFD, and use it in all places that set MSR_IA32_XFD.

Pull timer fixes from Thomas Gleixner: "Two regression fixes for the timer and timer migration code: - Prevent endless timer requeuing which is caused by two CPUs racing out of idle. This happens when the last CPU goes idle and therefore has to ensure to expire the pending global timers and some other CPU come out of idle at the same time and the other CPU wins the race and expires the global queue. This causes the last CPU to chase ghost timers forever and reprogramming it's clockevent device endlessly. Cure this by re-evaluating the wakeup time unconditionally. - The split into local (pinned) and global timers in the timer wheel caused a regression for NOHZ full as it broke the idle tracking of global timers. On NOHZ full this prevents an self IPI being sent which in turn causes the timer to be not programmed and not being expired on time. Restore the idle tracking for the global timer base so that the self IPI condition for NOHZ full is working correctly again" * tag 'timers-urgent-2024-03-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: timers: Fix removed self-IPI on global timer's enqueue in nohz_full timers/migration: Fix endless timer requeue after idle interrupts -
