2024-12-02nvme: don't apply NVME_QUIRK_DEALLOCATE_ZEROES when DSM is not supportedChristoph Hellwig
Commit 63dfa1004322 ("nvme: move NVME_QUIRK_DEALLOCATE_ZEROES out of nvme_config_discard") started applying the NVME_QUIRK_DEALLOCATE_ZEROES quirk even then the Dataset Management is not supported. It turns out that there versions of these old Intel SSDs that have DSM support disabled in the firmware, which will now lead to errors everytime a Write Zeroes command is issued. Fix this by checking for DSM support before applying the quirk.

2024-12-02nvmet: use kzalloc instead of ZERO_PAGE in nvme_execute_identify_ns_nvm()Nilay Shroff
The nvme_execute_identify_ns_nvm function uses ZERO_PAGE for copying SG list with all zeros. As ZERO_PAGE would not necessarily return the virtual-address of the zero page, we need to first convert the page address to kernel virtual-address and then use it as source address for copying the data to SG list with all zeros. Using return address of ZERO_PAGE(0) as source address for copying data to SG list would fill the target buffer with random/garbage value and causes the undesired side effect. As other identify implemenations uses kzalloc for allocating a zero filled buffer, we decided use kzalloc for allocating a zero filled buffer in nvme_execute_identify_ns_nvm function and then use this buffer for copying all zeros to SG list buffers. So esentially, we now avoid using ZERO_PAGE.

2024-12-02mmc: core: Further prevent card detect during shutdownUlf Hansson
Disabling card detect from the host's ->shutdown_pre() callback turned out to not be the complete solution. More precisely, beyond the point when the mmc_bus->shutdown() has been called, to gracefully power off the card, we need to prevent card detect. Otherwise the mmc_rescan work may poll for the card with a CMD13, to see if it's still alive, which then will fail and hang as the card has already been powered off. To fix this problem, let's disable mmc_rescan prior to power off the card during shutdown.

And it should be the same with invalid pmd entry, since pmd_none() is called by function free_pgd_range() and pmd_none() return 0 by huge_pte_clear(). So single _PAGE_HUGE bit is also treated as a valid pte table and free_pte_range() will be called in free_pmd_range(). free_pmd_range() pmd = pmd_offset(pud, addr); do { next = pmd_addr_end(addr, end); if (pmd_none_or_clear_bad(pmd)) continue; free_pte_range(tlb, pmd, addr); } while (pmd++, addr = next, addr != end); Here invalid_pte_table is used for both invalid huge pte entry and pmd entry.

At the end of __regmap_init(), if dev is not NULL, regmap_attach_dev() is called, which adds a devres reference to the regmap, to be able to retrieve a dev's regmap by name using dev_get_regmap(). When calling regmap_exit, the opposite does not happen, and the reference is kept until the dev is detached. Add a regmap_detach_dev() function and call it in regmap_exit() to make sure that the devres reference is not kept.

2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

These components are often connected to the mainboard via ribbon cables, having the same signals and pin assignments across all options. These may include the display panel and touchscreen on laptops and tablets, and the trackpad on laptops. Sometimes which component option is used in a particular device can be detected by some firmware provided identifier, other times that information is not available, and the kernel has to try to probe each device. Instead of a delicate dance between drivers and device tree quirks, this change introduces a simple I2C component probe function.
