commit 4949009e upstream. LCD driver is always built for the XTFPGA platform, but its base address is not configurable, and is wrong for ML605/KC705. Its initialization locks up KC705 board hardware. Make the whole driver optional, and its base address and bus width configurable. Implement 4-bit bus access method. Signed-off-by:

commit 0ee0d349 upstream. It is reported that ACPI interrupts do not work any more on Dell Latitude D600 after commit c50f13c6 (ACPICA: Save current masks of enabled GPEs after enable register writes). The problem turns out to be related to the fact that the enable_mask and enable_for_run GPE bit masks are not in sync (in the absence of any system suspend/resume events) for at least one GPE register on that machine. Address this problem by writing the enable_for_run mask into enable_mask as soon as enable_for_run is updated instead of doing that only after the subsequent register write has succeeded. For consistency, update acpi_hw_gpe_enable_write() to store the bit mask to be written into the GPE register in enable_mask unconditionally before the write. Since the ACPI_GPE_SAVE_MASK flag is not necessary any more after that, drop it along with the symbols depending on it. Reported-and-tested-by:

commit 2b876010 upstream. ACPICA commit aacf863cfffd46338e268b7415f7435cae93b451 It is reported that on a physically 64-bit addressed machine, 32-bit kernel can trigger crashes in accessing the memory regions that are beyond the 32-bit boundary. The region field's start address should still be 32-bit compliant, but after a calculation (adding some offsets), it may exceed the 32-bit boundary. This case is rare and buggy, but there are real BIOSes leaked with such issues (see References below). This patch fixes this gap by always defining IO addresses as 64-bit, and allows OSPMs to optimize it for a real 32-bit machine to reduce the size of the internal objects. Internal acpi_physical_address usages in the structures that can be fixed by this change include: 1. struct acpi_object_region: acpi_physical_address address; 2. struct acpi_address_range: acpi_physical_address start_address; acpi_physical_address end_address; 3. struct acpi_mem_space_context; acpi_physical_address address; 4. struct acpi_table_desc acpi_physical_address address; See known issues 1 for other usages. Note that acpi_io_address which is used for ACPI_PROCESSOR may also suffer from same problem, so this patch changes it accordingly. For iasl, it will enforce acpi_physical_address as 32-bit to generate 32-bit OSPM compatible tables on 32-bit platforms, we need to define ACPI_32BIT_PHYSICAL_ADDRESS for it in acenv.h. Known issues: 1. Cleanup of mapped virtual address In struct acpi_mem_space_context, acpi_physical_address is used as a virtual address: acpi_physical_address mapped_physical_address; It is better to introduce acpi_virtual_address or use acpi_size instead. This patch doesn't make such a change. Because this should be done along with a change to acpi_os_map_memory()/acpi_os_unmap_memory(). There should be no functional problem to leave this unchanged except that only this structure is enlarged unexpectedly.

commit b0dd00ad upstream. The conversion from __get_cpu_var() to this_cpu_ptr() in iic_setup_cpu() is wrong. It causes an oops at boot. We need the per-cpu address of struct cpu_iic, not cpu_iic.regs->prio. Sparse noticed this, because we pass a non-iomem pointer to out_be64(), but we obviously don't check the sparse results often enough.

commit 905e8c5d upstream. When running a compat (AArch32) userspace on Cortex-A53, a load at EL0 from a virtual address that matches the bottom 32 bits of the virtual address used by a recent load at (AArch64) EL1 might return incorrect data. This patch works around the issue by writing to the contextidr_el1 register on the exception return path when returning to a 32-bit task. This workaround is patched in at runtime based on the MIDR value of the processor. Reviewed-by:

commit 137650aa upstream. Currently we only perform alternative patching for kernels built with CONFIG_SMP, as we call apply_alternatives_all() in smp.c, which is only built for CONFIG_SMP. Thus !SMP kernels may not have necessary alternatives patched in. This patch ensures that we call apply_alternatives_all() once all CPUs are booted, even for !SMP kernels, by having the smp_init_cpus() stub call this for !SMP kernels via up_late_init. A new wrapper, do_post_cpus_up_work, is added so we can hook other calls here later (e.g. boot mode logging).

The EFI libstub directory is referenced by the kernel build system via a obj subdirectory rule in: drivers/firmware/efi/Makefile Unfortunately, arm64 also references the EFI libstub via: libs-$(CONFIG_EFI_STUB) += drivers/firmware/efi/libstub/ If we're unlucky, the kernel build system can enter libstub via two simultaneous threads resulting in build failures such as: fixdep: error opening depfile: drivers/firmware/efi/libstub/.efi-stub-helper.o.d: No such file or directory scripts/Makefile.build:257: recipe for target 'drivers/firmware/efi/libstub/efi-stub-helper.o' failed make[1]: *** [drivers/firmware/efi/libstub/efi-stub-helper.o] Error 2 Makefile:939: recipe for target 'drivers/firmware/efi/libstub' failed make: *** [drivers/firmware/efi/libstub] Error 2 make: *** Waiting for unfinished jobs....

commit 91d57155 upstream. After writing the page tables, we use __inval_cache_range to invalidate any stale cache entries. Strongly Ordered memory accesses are not ordered w.r.t. cache maintenance instructions, and hence explicit memory barriers are required to provide this ordering. However, __inval_cache_range was written to be used on Normal Cacheable memory once the MMU and caches are on, and does not have any barriers prior to the DC instructions. This patch adds a DMB between the page tables being written and the corresponding cachelines being invalidated, ensuring that the invalidation makes the new data visible to subsequent cacheable accesses. A barrier is not required before the prior invalidate as we do not access the page table memory area prior to this, and earlier barriers in preserve_boot_args and set_cpu_boot_mode_flag ensures ordering w.r.t. any stores performed prior to entering Linux.

However, variant and revision fields in MIDR_EL1 are separated by 16 bits, so the min and max of midr range should be constructed accordingly, otherwise the patch will not be applied when variant field is non-0.

commit c8367778 upstream. In fd_do_prot_rw(), it allocates prot_buf which is used to copy from se_cmd->t_prot_sg by sbc_dif_copy_prot(). The SG table for prot_buf is also initialized by allocating 'se_cmd->t_prot_nents' entries of scatterlist and setting the data length of each entry to PAGE_SIZE at most. However if se_cmd->t_prot_sg contains a clustered entry (i.e. sg->length > PAGE_SIZE), the SG table for prot_buf can't be initialized correctly and sbc_dif_copy_prot() can't copy to prot_buf. (This actually happened with TCM loopback fabric module) As prot_buf is allocated by kzalloc() and it's physically contiguous, we only need a single scatterlist entry. Signed-off-by:

commit 38da0f49 upstream. When CONFIG_DEBUG_SG=y and DIF protection support enabled, kernel BUG()s are triggered due to the following two issues: 1) prot_sg is not initialized by sg_init_table(). When CONFIG_DEBUG_SG=y, scatterlist helpers check sg entry has a correct magic value. 2) vmalloc'ed buffer is passed to sg_set_buf(). sg_set_buf() uses virt_to_page() to convert virtual address to struct page, but it doesn't work with vmalloc address. vmalloc_to_page() should be used instead. As prot_buf isn't usually too large, so fix it by allocating prot_buf by kmalloc instead of vmalloc. Signed-off-by:

commit c8e63985 upstream. This patch fixes a bug for COMPARE_AND_WRITE handling with fabrics using SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC. It adds the missing allocation for cmd->t_bidi_data_sg within transport_generic_new_cmd() that is used by COMPARE_AND_WRITE for the initial READ payload, even if the fabric is already providing a pre-allocated buffer for cmd->t_data_sg. Also, fix zero-length COMPARE_AND_WRITE handling within the compare_and_write_callback() and target_complete_ok_work() to queue the response, skipping the initial READ. This fixes COMPARE_AND_WRITE emulation with loopback, vhost, and xen-backend fabric drivers using SG_TO_MEM_NOALLOC. Reported-by:

commit 34d47b63 upstream. I started to work with PPI interface so that it would be available under character device sysfs directory and realized that chip registeration was still too messy. In TPM 1.x in some rare scenarios (errors that almost never occur) wrong order in deinitialization steps was taken in teardown. I reproduced these scenarios by manually inserting error codes in the place of the corresponding function calls. The key problem is that the teardown is messy with two separate code paths (this was inherited when moving code from tpm-interface.c). Moved TPM 1.x specific register/unregister functionality to own helper functions and added single code path for teardown in tpm_chip_register(). Now the code paths have been fixed and it should be easier to review later on this part of the code. Fixes: 7a1d7e6d ("tpm: TPM 2.0 baseline support") Signed-off-by:

commit e0c9c0af upstream. Now that it is possible to lazily unmount an entire mount tree and leave the individual mounts connected to each other add a new flag UMOUNT_CONNECTED to umount_tree to force this behavior and use this flag in detach_mounts. This closes a bug where the deletion of a file or directory could trigger an unmount and reveal data under a mount point. Signed-off-by:
