In addition to offsets of certain registers changing, the registers in core_mem have been shifted to HC mem as well. To access these registers, define msm version specific functions. These functions can be loaded into the function pointers at the time of probe based on the msm version detected. Also defind new data structure to hold version specific Ops and register addresses.

Simon Horman authored
This adds two new HS400 tuning operations: * hs400_downgrade * hs400_complete These supplement the existing HS400 operation: * prepare_hs400_tuning This is motivated by a requirement of Renesas SDHI for the following: 1. Disabling SCC before selecting to HS if selection of HS400 has occurred. This can be done in an implementation of prepare_hs400_tuning_downgrade 2. Updating registers after switching to HS400 This can be done in an implementation of complete_hs400_tuning If hs400_downgrade or hs400_complete are not implemented then they are not called. Thus means there should be no affect for existing drivers as none implemt these ops. Signed-off-by:

dw_mci_exynos_resume_noirq() performs DWMMC register access without ensuring that respective clocks are enabled. This might cause external abort on some systems (observed on Exynos5433 based boards). Fix this by forcing a PM runtime active state before register access. Using SET_NOIRQ_SYSTEM_SLEEP_PM_OPS allows also to cleanup conditional code a bit. Suggested-by:

The sdhci get_max_clock callback is set to sdhci_pltfm_clk_get_max_clock and tegra_sdhci_get_max_clock is removed. It appears that the shdci-tegra specific callback was originally introduced due to the requirement that the host clock has to be twice the bus clock on DDR50 mode. As far as I can tell the only effect the removal has on DDR50 mode is in cases where the parent clock is unable to supply the requested clock rate, causing the DDR50 mode to run at a lower frequency. Currently the DDR50 mode isn't enabled on any of the SoCs and would also require configuring the SDHCI clock divider register to function properly. The problem with tegra_sdhci_get_max_clock is that it divides the clock rate by two and thus artificially limits the maximum frequency of faster signaling modes which don't have the host-bus frequency ratio requirement of DDR50 such as SDR104 and HS200. Furthermore, the call to clk_round_rate() may return an error which isn't handled by tegra_sdhci_get_max_clock. Signed-off-by:

R1_STATUS(x) now is only used by ioctl_rpmb_card_status_poll(), which checks all bits as possible. But according to the spec, bit 17 and bit 18 should be ignored, as well bit 14 which is reserved(must be set to 0) quoting from the spec and these rule apply to all places checking the device status. So change its checking from 0xFFFFE000 to 0xFFF9A000. As a bonus, we reuse it for mmc_do_erase() as well as mmc_switch_status_error(). (1) Currently mmc_switch_status_error() doesn't check bit 25, but it means device is locked but not unlocked by CMD42 prior to any operations which need check busy, which is also not allowed. (2) mmc_do_erase() also forgot to to check bit 15, WP_ERASE_SKIP. The spec says "Only partial address space was erased due to existing write protected blocks.", which obviously means we should fail this I/O. Otherwise, the partial erased data stored in nonvalatile flash violates the data integrity from the view of I/O owner, which probably confuse it when further used. So reusing R1_STATUS for them not only improve the readability but also slove real problems. Signed-off-by:

Merge tag 'omap-for-v4.18/fixes-rc4-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes Two omap fixes for v4.18-rc cycle Turns out the recent patches for ARM branch predictor hardening are not working on omap5 and dra7 as planned because the secondary CPU is parked to the bootrom code. We can't configure it in the bootloader. So we must enable invalidates of BTB for omap5 and dra7 secondary core in the kernel. And there's a fix for reserved register access for am3517.

ReiserFS prepares log messages into a 1024-byte buffer with no bounds checks. Long messages, such as the "unknown mount option" warning when userspace passes a crafted mount options string, overflow this buffer. This causes KASAN to report a global-out-of-bounds write. Fix it by truncating messages to the buffer size.

There is no reason to bug on that though. do_brk_flags already aligns the length properly so the mapping is expanded as it should. All we need is to tell mm_populate about it. Besides that there is absolutely no reason to to bug_on in the first place. The worst thing that could happen is that the last page wouldn't get populated and that is far from putting system into an inconsistent state. Fix the issue by moving the length sanitization code from do_brk_flags up to vm_brk_flags. The only other caller of do_brk_flags is brk syscall entry and it makes sure to provide the proper length so t here is no need for sanitation and so we can use do_brk_flags without it. Also remove the bogus BUG_ONs.

Also readelf -S still shows the .eh_frame section for sha256.o. With the fix sha256.o is rebuilt in the last step. Without FORCE make does not detect changes only made to the command line options.

In my testing, the second mount will fail after umounting successfully. The reason is that we put refcount of trans_mod in the correct case rather than the error case in parse_opts() at last. That will cause the refcount decrease to -1, and when we try to get trans_mod again in try_module_get(), we could only increase refcount to 0 which will cause failure as follows: parse_opts v9fs_get_trans_by_name try_module_get : return NULL to caller which cause error So we should put refcount of trans_mod in error case.

The mmu_gather APIs keep track of the invalidated address range including the span covered by invalidated page table pages. Ranges covered by page tables but not ptes (and therefore no TLBs) still need to be invalidated because some architectures (x86) can cache intermediate page table entries, and invalidate those with normal TLB invalidation instructions to be almost-backward-compatible. Architectures which don't cache intermediate page table entries, or which invalidate these caches separately from TLB invalidation, do not require TLB invalidation range expanded over page tables. Allow architectures to supply their own p??_free_tlb functions, which can avoid the __tlb_adjust_range. Link: http://lkml.kernel.org/r/20180703013131.2807-1-npiggin@gmail.comSigned-off-by:

Notice the VM_LOCKED check. (vma->vm_flags & VM_LOCKED) ?

KVM guests on s390 can notify the host of unused pages. This can result in pte_unused callbacks to be true for KVM guest memory. If a page is unused (checked with pte_unused) we might drop this page instead of paging it. This can have side-effects on userfaultd, when the page in question was already migrated: The next access of that page will trigger a fault and a user fault instead of faulting in a new and empty zero page. As QEMU does not expect a userfault on an already migrated page this migration will fail. The most straightforward solution is to ignore the pte_unused hint if a userfault context is active for this VMA.

We must zero struct pages for memory that is not backed by physical memory, or kernel does not have access to. Recently, there was a change which zeroed all memmap for all holes in e820. Unfortunately, it introduced a bug that is discussed here: https://www.spinics.net/lists/linux-mm/msg156764.html Linus, also saw this bug on his machine, and confirmed that reverting commit 124049de ("x86/e820: put !E820_TYPE_RAM regions into memblock.reserved") fixes the issue. The problem is that we incorrectly zero some struct pages after they were setup. The fix is to zero unavailable struct pages prior to initializing of struct pages. A more detailed fix should come later that would avoid double zeroing cases: one in __init_single_page(), the other one in zero_resv_unavail().

Pull arm64 fixes from Will Deacon: "Catalin's out enjoying the sunshine, so I'm sending the fixes for a couple of weeks (although there hopefully won't be any more!).
