+Subject: ALSA: hda: ignore invalid NHLT table
+
+From: Mark Pearson <markpearson@lenovo.com>
+
+[ Upstream commit a14a6219996ee6f6e858d83b11affc7907633687 ]
+
+On some Lenovo systems if the microphone is disabled in the BIOS
+only the NHLT table header is created, with no data. This means
+the endpoints field is not correctly set to zero - leading to an
+unintialised variable and hence invalid descriptors are parsed
+leading to page faults.
+
+The Lenovo firmware team is addressing this, but adding a check
+preventing invalid tables being parsed is worthwhile.
+
+Tested on a Lenovo T14.

+Subject: atm: eni: dont release is never initialized
+
+From: Tong Zhang <ztong0001@gmail.com>
+
+[ Upstream commit 4deb550bc3b698a1f03d0332cde3df154d1b6c1e ]
+
+label err_eni_release is reachable when eni_start() fail.
+In eni_start() it calls dev->phy->start() in the last step, if start()
+fail we don't need to call phy->stop(), if start() is never called, we
+neither need to call phy->stop(), otherwise null-ptr-deref will happen.
+
+In order to fix this issue, don't call phy->stop() in label err_eni_release

+Subject: atm: idt77252: fix null-ptr-dereference
+
+From: Tong Zhang <ztong0001@gmail.com>
+
+[ Upstream commit 4416e98594dc04590ebc498fc4e530009535c511 ]
+
+this one is similar to the phy_data allocation fix in uPD98402, the
+driver allocate the idt77105_priv and store to dev_data but later
+dereference using dev->dev_data, which will cause null-ptr-dereference.
+
+fix this issue by changing dev_data to phy_data so that PRIV(dev) can
+work correctly.

+From: Tong Zhang <ztong0001@gmail.com>
+
+[ Upstream commit a2bd45834e83d6c5a04d397bde13d744a4812dfc ]
+
+lanai_dev_open() can fail. When it fail, lanai->base is unmapped and the
+pci device is disabled. The caller, lanai_init_one(), then tries to run
+atm_dev_deregister(). This will subsequently call lanai_dev_close() and
+use the already released MMIO area.
+
+To fix this issue, set the lanai->base to NULL if open fail,
+and test the flag in lanai_dev_close().

+
+From: Tong Zhang <ztong0001@gmail.com>
+
+[ Upstream commit 3153724fc084d8ef640c611f269ddfb576d1dcb1 ]
+
+dev->dev_data is set in zatm.c, calling zatm_start() will overwrite this
+dev->dev_data in uPD98402_start() and a subsequent PRIV(dev)->lock
+(i.e dev->phy_data->lock) will result in a null-ptr-dereference.
+
+I believe this is a typo and what it actually want to do is to allocate
+phy_data instead of dev_data.

+
+From: Daniel Wagner <dwagner@suse.de>
+
+[ Upstream commit 9ec491447b90ad6a4056a9656b13f0b3a1e83043 ]
+
+register_disk() suppress uevents for devices with the GENHD_FL_HIDDEN
+but enables uevents at the end again in order to announce disk after
+possible partitions are created.
+
+When the device is removed the uevents are still on and user land sees
+'remove' messages for devices which were never 'add'ed to the system.
+
+ KERNEL[95481.571887] remove /devices/virtual/nvme-fabrics/ctl/nvme5/nvme0c5n1 (block)
+
+Let's suppress the uevents for GENHD_FL_HIDDEN by not enabling the
+uevents at all.

+

+
+When doing a large read or write workload we only
+very gradually increase the number of credits
+which can cause problems with parallelizing large i/o
+(I/O ramps up more slowly than it should for large
+read/write workloads) especially with multichannel
+when the number of credits on the secondary channels
+starts out low (e.g. less than about 130) or when
+recovering after server throttled back the number
+of credit.

+So at t=7 a new packets is started but not finished, probably due to rx
+overrun - but rx overrun is not indicated in the flags. Instead a new
+packets starts at t=8. This results in skb->len to exceed size for the LAST
+fragment at t=13 and thus a negative fragment size added to the skb.
+
+This then crashes:

+In order to prevent the newer rx frame from getting corrupted, the FIRST

+
+The refcount of the "hl_fpriv" structure is not used for the control

+This results with no call to put_pid(), so add it explicitly in

+Subject: ia64: fix ia64_syscall_get_set_arguments() for break-based syscalls
+
+From: Sergei Trofimovich <slyfox@gentoo.org>
+
+[ Upstream commit 0ceb1ace4a2778e34a5414e5349712ae4dc41d85 ]
+
+In https://bugs.gentoo.org/769614 Dmitry noticed that
+`ptrace(PTRACE_GET_SYSCALL_INFO)` does not work for syscalls called via
+glibc's syscall() wrapper.
+
+ia64 has two ways to call syscalls from userspace: via `break` and via
+`eps` instructions.
+
+The difference is in stack layout:
+
+1. `eps` creates simple stack frame: no locals, in{0..7} == out{0..8}
+2. `break` uses userspace stack frame: may be locals (glibc provides
+ one), in{0..7} == out{0..8}.
+
+Both work fine in syscall handling cde itself.
+
+But `ptrace(PTRACE_GET_SYSCALL_INFO)` uses unwind mechanism to
+re-extract syscall arguments but it does not account for locals.
+
+The change always skips locals registers. It should not change `eps`
+path as kernel's handler already enforces locals=0 and fixes `break`.
+
+Tested on v5.10 on rx3600 machine (ia64 9040 CPU).

+Subject: net: fec: ptp: avoid register access when ipg clock is disabled
+
+From: Heiko Thiery <heiko.thiery@gmail.com>
+
+[ Upstream commit 6a4d7234ae9a3bb31181f348ade9bbdb55aeb5c5 ]
+
+When accessing the timecounter register on an i.MX8MQ the kernel hangs.
+This is only the case when the interface is down. This can be reproduced
+by reading with 'phc_ctrl eth0 get'.
+
+Like described in the change in 91c0d987a9788dcc5fe26baafd73bf9242b68900
+the igp clock is disabled when the interface is down and leads to a
+system hang.
+
+So we check if the ptp clock status before reading the timecounter
+register.

+The NFSv4 protocol doesn't have any notion of reomoving an attribute, so

+
+There's no documented return value. Arguably it could be EOPNOTSUPP but

+Subject: powerpc/4xx: Fix build errors from mfdcr()
+
+From: Michael Ellerman <mpe@ellerman.id.au>
+
+[ Upstream commit eead089311f4d935ab5d1d8fbb0c42ad44699ada ]
+
+lkp reported a build error in fsp2.o:
+
+ CC arch/powerpc/platforms/44x/fsp2.o
+ {standard input}:577: Error: unsupported relocation against base
+
+Which comes from:
+
+ pr_err("GESR0: 0x%08x\n", mfdcr(base + PLB4OPB_GESR0));
+
+Where our mfdcr() macro is stringifying "base + PLB4OPB_GESR0", and
+passing that to the assembler, which obviously doesn't work.
+
+The mfdcr() macro already checks that the argument is constant using
+__builtin_constant_p(), and if not calls the out-of-line version of
+mfdcr(). But in this case GCC is smart enough to notice that "base +
+PLB4OPB_GESR0" will be constant, even though it's not something we can
+immediately stringify into a register number.
+
+Segher pointed out that passing the register number to the inline asm
+as a constant would be better, and in fact it fixes the build error,
+presumably because it gives GCC a chance to resolve the value.
+
+While we're at it, change mtdcr() similarly.

+Subject: Revert "r8152: adjust the settings about MAC clock speed down for
+ RTL8153"
+
+From: Hayes Wang <hayeswang@realtek.com>
+
+[ Upstream commit 4b5dc1a94d4f92b5845e98bd9ae344b26d933aad ]
+
+This reverts commit 134f98bcf1b898fb9d6f2b91bc85dd2e5478b4b8.
+
+The r8153_mac_clk_spd() is used for RTL8153A only, because the register
+table of RTL8153B is different from RTL8153A. However, this function would
+be called when RTL8153B calls r8153_first_init() and r8153_enter_oob().
+That causes RTL8153B becomes unstable when suspending and resuming. The
+worst case may let the device stop working.
+
+Besides, revert this commit to disable MAC clock speed down for RTL8153A.
+It would avoid the known issue when enabling U1. The data of the first
+control transfer may be wrong when exiting U1.

+Subject: sparc64: Fix opcode filtering in handling of no fault loads
+
+From: Rob Gardner <rob.gardner@oracle.com>
+
+[ Upstream commit e5e8b80d352ec999d2bba3ea584f541c83f4ca3f ]
+
+is_no_fault_exception() has two bugs which were discovered via random
+opcode testing with stress-ng. Both are caused by improper filtering
+of opcodes.
+
+The first bug can be triggered by a floating point store with a no-fault
+ASI, for instance "sta %f0, [%g0] #ASI_PNF", opcode C1A01040.
+
+The code first tests op3[5] (0x1000000), which denotes a floating
+point instruction, and then tests op3[2] (0x200000), which denotes a
+store instruction. But these bits are not mutually exclusive, and the
+above mentioned opcode has both bits set. The intent is to filter out
+stores, so the test for stores must be done first in order to have
+any effect.
+
+The second bug can be triggered by a floating point load with one of
+the invalid ASI values 0x8e or 0x8f, which pass this check in
+is_no_fault_exception():
+ if ((asi & 0xf2) == ASI_PNF)
+
+An example instruction is "ldqa [%l7 + %o7] #ASI 0x8f, %f38",
+opcode CF95D1EF. Asi values greater than 0x8b (ASI_SNFL) are fatal
+in handle_ldf_stq(), and is_no_fault_exception() must not allow these
+invalid asi values to make it that far.
+
+In both of these cases, handle_ldf_stq() reacts by calling
+sun4v_data_access_exception() or spitfire_data_access_exception(),
+which call is_no_fault_exception() and results in an infinite
+recursion.

+results in lockdep getting confused between the RX and TX stats lock.
+This is because u64_stats_init() is an inline calling seqcount_init(),
+which is a macro using a static variable to generate a lockdep class.
+
+By wrapping that in an inline, we negate the effect of the macro and
+fold the static key variable, hence the confusion.
+
+Fix by also making u64_stats_init() a macro for the case where it
+matters, leaving the other case an inline for argument validation
+etc.
