When the core is configured in C_SPI_MODE > 0, it integrates a lookup table that automatically configures the core in dual or quad mode based on the command (first byte on the tx fifo). Unfortunately, that list mode_?_memoy_*.mif does not contain all the supported commands by the flash. Since 4.14 spi-nor automatically tries to probe the flash using SFDP (command 0x5a), and that command is not part of the list_mode table. Whit the right combination of C_SPI_MODE and C_SPI_MEMORY this leads into a stall that can only be recovered with a soft rest. This patch detects this kind of stall and returns -EIO to the caller on those commands. spi-nor can handle this error properly: m25p80 spi0.0: Detected stall. Check C_SPI_MODE and C_SPI_MEMORY. 0x21 0x2404 m25p80 spi0.0: SPI transfer failed: -5 spi_master spi0: failed to transfer one message from queue m25p80 spi0.0: s25sl064p (8192 Kbytes) Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org

If the array is not present, assume all chip selects are native. This is the standard behavior for SPI masters configured via the device tree and the behavior of this driver as well when it is configured via device tree. This reduces platform data vs DT differences and allows most of the platform data based boards to remove their chip select arrays.

If the code that requests any chip select GPIOs fails, the cleanup of spi_bitbang_start() by calling spi_bitbang_stop() is not done. Add this to the failure path. Note that spi_bitbang_start() has to be called before requesting GPIOs because the GPIO data in the spi master is populated when the master is registed, and that doesn't happen until spi_bitbang_start() is called.

The driver will fail to load if no gpio chip selects are specified, this patch changes this so that it no longer fails. It's possible to use all native chip selects, in which case there is no reason to have a gpio chip select array. This is what happens if the *optional* device tree property "cs-gpios" is omitted. The spi core already checks for the absence of gpio chip selects in the master and assigns any slaves the gpio_cs value of -ENOENT. Also have the driver respect the standard SPI device tree property "num-cs" to allow setting the number of chip selects without using cs-gpios.

There have been some cases where external tooling (e.g., kpatch-build) creates a corrupt relocation which targets the wrong address. This is a silent failure which can corrupt memory in unexpected places. On x86, the bytes of data being overwritten by relocations are always initialized to zero beforehand. Use that knowledge to add sanity checks to detect such cases before they corrupt memory.

tools/include/uapi/linux/sched.h,
tools/include/uapi/linux/vhost.h,
tools/include/uapi/sound/asound.h:
Add the SPDX tag of the respective kernel header.
- tools/include/uapi/linux/bpf_common.h,
tools/include/uapi/linux/fcntl.h,
tools/include/uapi/linux/hw_breakpoint.h,
tools/include/uapi/linux/mman.h,

Also sync other header details:
- include/uapi/sound/asound.h:
Fix pointless end of line whitespace noise the header grew in this cycle.
- tools/arch/x86/lib/memcpy_64.S:
Sync the code and add tools/include/asm/export.h with dummy wrappers

Sync events are sent by sparse_keymap_report_entry for normal KEY_* events, and are generated by several drivers after generating SW_* events, so sparse_keymap_report_entry should do the same. Without the sync, events are accumulated in the kernel. Currently, no driver uses sparse-keymap for SW_* events, but it is required for the intel-vbtn platform driver to generate SW_TABLET_MODE events.

set_state_oneshot_stopped() is called by the clkevt core, when the
next event is required at an expiry time of 'KTIME_MAX'. This normally
happens with NO_HZ_{IDLE|FULL} in both LOWRES/HIGHRES modes.
This patch makes the clockevent device to stop on such an event, to
avoid spurious interrupts, as explained by: commit

A fix to the handling of misaligned paste instructions (P9 only), where a change
to a #define has caused the check for the instruction to always fail.
The preempt handling was unbalanced in the radix THP flush (P9 only). Though we
don't generally use preempt we want to keep it working as much as possible.
Two fixes for IMC (P9 only), one when booting with restricted number of CPUs and
one in the error handling when initialisation fails due to firmware etc.
A revert to fix function_graph on big endian machines, and then a rework of the
reverted patch to fix kprobes blacklist handling on big endian machines.

MIPS will soon not be a part of Imagination Technologies, and as such many @imgtec.com email addresses will no longer be valid. This patch updates the addresses for those who: - Have 10 or more patches in mainline authored using an @imgtec.com email address, or any patches dated within the past year. - Are still with Imagination but leaving as part of the MIPS business unit, as determined from an internal email address list. - Haven't already updated their email address (ie. JamesH) or expressed a desire to be excluded (ie. Maciej). - Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt & myself. New addresses are of the form firstname.lastname@mips.com, and all verified against an internal email address list. An entry is added to .mailmap for each person such that get_maintainer.pl will report the new addresses rather than @imgtec.com addresses which will soon be dead. Instances of the affected addresses throughout the tree are then mechanically replaced with the new @mips.com address.

One page may store a set of entries of the sis->swap_map
(swap_info_struct->swap_map) in multiple swap clusters.
If some of the entries has sis->swap_map[offset] > SWAP_MAP_MAX,
multiple pages will be used to store the set of entries of the
sis->swap_map. And the pages are linked with page->lru. This is called
swap count continuation. To access the pages which store the set of
entries of the sis->swap_map simultaneously, previously, sis->lock is
used. But to improve the scalability of __swap_duplicate(), swap
cluster lock may be used in swap_count_continued() now. This may race
with add_swap_count_continuation() which operates on a nearby swap
cluster, in which the sis->swap_map entries are stored in the same page.
The race can cause wrong swap count in practice, thus cause unfreeable
swap entries or software lockup, etc.
To fix the race, a new spin lock called cont_lock is added to struct
swap_info_struct to protect the swap count continuation page list. This
is a lock at the swap device level, so the scalability isn't very well.
But it is still much better than the original sis->lock, because it is
only acquired/released when swap count continuation is used. Which is
considered rare in practice. If it turns out that the scalability
becomes an issue for some workloads, we can split the lock into some
more fine grained locks.

We need to deposit pre-allocated PTE page table when a PMD migration
entry is copied in copy_huge_pmd(). Otherwise, we will leak the

as well.

Calling madvise(MADV_HWPOISON) on a hugetlbfs page will result in bad
(negative) reserved huge page counts. This may not happen immediately,
but may happen later when the underlying file is removed or filesystem
unmounted. For example:
AnonHugePages: 0 kB
ShmemHugePages: 0 kB
HugePages_Total: 1
HugePages_Free: 0
HugePages_Rsvd: 18446744073709551615
HugePages_Surp: 0
Hugepagesize: 2048 kB
In routine hugetlbfs_error_remove_page(), hugetlb_fix_reserve_counts is
called after remove_huge_page. hugetlb_fix_reserve_counts is designed
to only be called/used only if a failure is returned from
hugetlb_unreserve_pages. Therefore, call hugetlb_unreserve_pages as
required and only call hugetlb_fix_reserve_counts in the unlikely event
that hugetlb_unreserve_pages returns an error.

The first cluster group descriptor is not stored at the start of the group but at an offset from the start. We need to take this into account while doing fstrim on the first cluster group. Otherwise we will wrongly start fstrim a few blocks after the desired start block and the range can cross over into the next cluster group and zero out the group descriptor there. This can cause filesytem corruption that cannot be fixed by fsck.

When the pagetable is walked in the implementation of /proc/<pid>/pagemap,
pmd_soft_dirty() is used for both the PMD huge page map and the PMD
migration entries. That is wrong, pmd_swp_soft_dirty() should be used
for the PMD migration entries instead because the different page table
entry flag is used.
As a result, /proc/pid/pagemap may report incorrect soft dirty information
for PMD migration entries.
