+Subject: ALSA: firewire-motu: use 'version' field of unit directory to identify model
+
+From: Takashi Sakamoto <o-takashi@sakamocchi.jp>
+
+commit 2d012c65a9ca26a0ef87ea0a42f1653dd37155f5 upstream.
+
+Current ALSA firewire-motu driver uses the value of 'model' field
+of unit directory in configuration ROM for modalias for MOTU
+FireWire models. However, as long as I checked, Pre8 and
+828mk3(Hybrid) have the same value for the field (=0x100800).
+
+unit            | version   | model
+--------------- | --------- | ----------
+828mkII         | 0x000003  | 0x101800
+Traveler        | 0x000009  | 0x107800
+Pre8            | 0x00000f  | 0x100800 <-
+828mk3(FW)      | 0x000015  | 0x106800
+AudioExpress    | 0x000033  | 0x104800
+828mk3(Hybrid)  | 0x000035  | 0x100800 <-
+
+When updating firmware for MOTU 8pre FireWire from v1.0.0 to v1.0.3,
+I got change of the value from 0x100800 to 0x103800. On the other
+hand, the value of 'version' field is fixed to 0x00000f. As a quick
+glance, the higher 12 bits of the value of 'version' field represent
+firmware version, while the lower 12 bits is unknown.
+
+By induction, the value of 'version' field represents actual model.
+
+This commit changes modalias to match the value of 'version' field,
+instead of 'model' field. For degug, long name of added sound card
+includes hexadecimal value of 'model' field.

+Subject: drm/vmwgfx: Don't double-free the mode stored in par->set_mode
+
+From: Thomas Zimmermann <tzimmermann@suse.de>
+
+commit c2d311553855395764e2e5bf401d987ba65c2056 upstream.
+
+When calling vmw_fb_set_par(), the mode stored in par->set_mode gets free'd
+twice. The first free is in vmw_fb_kms_detach(), the second is near the
+end of vmw_fb_set_par() under the name of 'old_mode'. The mode-setting code
+only works correctly if the mode doesn't actually change. Removing
+'old_mode' in favor of using par->set_mode directly fixes the problem.

+Subject: iommu/amd: fix sg->dma_address for sg->offset bigger than PAGE_SIZE
+
+From: Stanislaw Gruszka <sgruszka@redhat.com>
+
+commit 4e50ce03976fbc8ae995a000c4b10c737467beaa upstream.
+
+Take into account that sg->offset can be bigger than PAGE_SIZE when
+setting segment sg->dma_address. Otherwise sg->dma_address will point
+at diffrent page, what makes DMA not possible with erros like this:
+
+xhci_hcd 0000:38:00.3: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0000 address=0x00000000fdaa70c0 flags=0x0020]

+
+Additinally with wrong sg->dma_address unmap_sg will free wrong pages,
+what what can cause crashes like this:

+Subject: libceph: wait for latest osdmap in ceph_monc_blacklist_add()
+
+From: Ilya Dryomov <idryomov@gmail.com>
+
+commit bb229bbb3bf63d23128e851a1f3b85c083178fa1 upstream.
+
+Because map updates are distributed lazily, an OSD may not know about
+the new blacklist for quite some time after "osd blacklist add" command
+is completed.  This makes it possible for a blacklisted but still alive
+client to overwrite a post-blacklist update, resulting in data
+corruption.
+
+Waiting for latest osdmap in ceph_monc_blacklist_add() and thus using
+the post-blacklist epoch for all post-blacklist requests ensures that
+all such requests "wait" for the blacklist to come into force on their
+respective OSDs.

+Subject: MIPS: Ensure ELF appended dtb is relocated
+
+From: Yasha Cherikovsky <yasha.che3@gmail.com>
+
+commit 3f0a53bc6482fb09770982a8447981260ea258dc upstream.
+
+This fixes booting with the combination of CONFIG_RELOCATABLE=y
+and CONFIG_MIPS_ELF_APPENDED_DTB=y.
+
+Sections that appear after the relocation table are not relocated
+on system boot (except .bss, which has special handling).
+
+With CONFIG_MIPS_ELF_APPENDED_DTB, the dtb is part of the
+vmlinux ELF, so it must be relocated together with everything else.

+Subject: mips: loongson64: lemote-2f: Add IRQF_NO_SUSPEND to "cascade" irqaction.
+
+From: Yifeng Li <tomli@tomli.me>
+
+commit 5f5f67da9781770df0403269bc57d7aae608fecd upstream.
+
+Timekeeping IRQs from CS5536 MFGPT are routed to i8259, which then
+triggers the "cascade" IRQ on MIPS CPU. Without IRQF_NO_SUSPEND in
+cascade_irqaction, MFGPT interrupts will be masked in suspend mode,
+and the machine would be unable to resume once suspended.
+
+Previously, MIPS IRQs were not disabled properly, so the original
+code appeared to work. Commit a3e6c1eff5 ("MIPS: IRQ: Fix disable_irq on
+CPU IRQs") uncovers the bug. To fix it, add IRQF_NO_SUSPEND to
+cascade_irqaction.
+
+This commit is functionally identical to 0add9c2f1cff ("MIPS:
+Loongson-3: Add IRQF_NO_SUSPEND to Cascade irqaction"), but it forgot
+to apply the same fix to Loongson2.

+commit e60a582bcde01158a64ff948fb799f21f5d31a11 upstream.
+
+clang points out several instances of mismatched types in this drivers,
+all coming from a single declaration:
+
+drivers/mmc/host/pxamci.c:193:15: error: implicit conversion from enumeration type 'enum dma_transfer_direction' to
+      different enumeration type 'enum dma_data_direction' [-Werror,-Wenum-conversion]

+        tx = dmaengine_prep_slave_sg(chan, data->sg, host->dma_len, direction,
+
+The behavior is correct, so this must be a simply typo from
+dma_data_direction and dma_transfer_direction being similarly named
+types with a similar purpose.

+
+commit c9a9497ccef205ed4ed2e247011382627876d831 upstream.
+
+R-Car Gen2 has two different SDHI incarnations in the same chip. The
+older one does not support the recently introduced 32 bit register
+access to the block count register. Make sure we use this feature only
+after the first known version.
+
+Thanks to the Renesas Testing team for this bug report!

+Subject: powerpc/vdso64: Fix CLOCK_MONOTONIC inconsistencies across Y2038
+
+From: Michael Ellerman <mpe@ellerman.id.au>
+
+commit b5b4453e7912f056da1ca7572574cada32ecb60c upstream.
+
+Jakub Drnec reported:
+  Setting the realtime clock can sometimes make the monotonic clock go
+  back by over a hundred years. Decreasing the realtime clock across
+  the y2k38 threshold is one reliable way to reproduce. Allegedly this
+  can also happen just by running ntpd, I have not managed to
+  reproduce that other than booting with rtc at >2038 and then running
+  ntp. When this happens, anything with timers (e.g. openjdk) breaks
+  rather badly.
+
+And included a test case (slightly edited for brevity):
+  #define _POSIX_C_SOURCE 199309L
+  #include <stdio.h>
+  #include <time.h>
+  #include <stdlib.h>
+  #include <unistd.h>
+
+  long get_time(void) {
+    struct timespec tp;
+    clock_gettime(CLOCK_MONOTONIC, &tp);
+    return tp.tv_sec + tp.tv_nsec / 1000000000;
+  }
+
+  int main(void) {
+    long last = get_time();
+    while(1) {
+      long now = get_time();
+      if (now < last) {
+        printf("clock went backwards by %ld seconds!\n", last - now);
+      }
+      last = now;
+      sleep(1);
+    }
+    return 0;
+  }
+
+Which when run concurrently with:
+ # date -s 2040-1-1
+ # date -s 2037-1-1
+
+Will detect the clock going backward.
+
+The root cause is that wtom_clock_sec in struct vdso_data is only a
+32-bit signed value, even though we set its value to be equal to
+tk->wall_to_monotonic.tv_sec which is 64-bits.
+
+Because the monotonic clock starts at zero when the system boots the
+wall_to_montonic.tv_sec offset is negative for current and future
+dates. Currently on a freshly booted system the offset will be in the
+vicinity of negative 1.5 billion seconds.
+
+However if the wall clock is set past the Y2038 boundary, the offset
+from wall to monotonic becomes less than negative 2^31, and no longer
+fits in 32-bits. When that value is assigned to wtom_clock_sec it is
+truncated and becomes positive, causing the VDSO assembly code to
+calculate CLOCK_MONOTONIC incorrectly.
+
+That causes CLOCK_MONOTONIC to jump ahead by ~4 billion seconds which
+it is not meant to do. Worse, if the time is then set back before the
+Y2038 boundary CLOCK_MONOTONIC will jump backward.
+
+We can fix it simply by storing the full 64-bit offset in the
+vdso_data, and using that in the VDSO assembly code. We also shuffle
+some of the fields in vdso_data to avoid creating a hole.
+
+The original commit that added the CLOCK_MONOTONIC support to the VDSO
+did actually use a 64-bit value for wtom_clock_sec, see commit
+a7f290dad32e ("[PATCH] powerpc: Merge vdso's and add vdso support to
+32 bits kernel") (Nov 2005). However just 3 days later it was
+converted to 32-bits in commit 0c37ec2aa88b ("[PATCH] powerpc: vdso
+fixes (take #2)"), and the bug has existed since then AFAICS.
+
+Fixes: 0c37ec2aa88b ("[PATCH] powerpc: vdso fixes (take #2)")
