2024-07-08drm/bridge: adv7511: Fix Intermittent EDID failuresAdam Ford
In the process of adding support for shared IRQ pins, a scenario was accidentally created where adv7511_irq_process returned prematurely causing the EDID to fail randomly. Since the interrupt handler is broken up into two main helper functions, update both of them to treat the helper functions as IRQ handlers. These IRQ routines process their respective tasks as before, but if they determine that actual work was done, mark the respective IRQ status accordingly, and delay the check until everything has been processed. This should guarantee the helper functions don't return prematurely while still returning proper values of either IRQ_HANDLED or IRQ_NONE.

2024-07-08xfrm: call xfrm_dev_policy_delete when kill policyJianbo Liu
xfrm_policy_kill() is called at different places to delete xfrm policy. It will call xfrm_pol_put(). But xfrm_dev_policy_delete() is not called to free the policy offloaded to hardware. The three commits cited here are to handle this issue by calling xfrm_dev_policy_delete() outside xfrm_get_policy(). But they didn't cover all the cases. An example, which is not handled for now, is xfrm_policy_insert(). It is called when XFRM_MSG_UPDPOLICY request is received. Old policy is replaced by new one, but the offloaded policy is not deleted, so driver doesn't have the chance to release hardware resources. To resolve this issue for all cases, move xfrm_dev_policy_delete() into xfrm_policy_kill(), so the offloaded policy can be deleted from hardware when it is called, which avoids hardware resources leakage. Fixes: 919e43fad516 ("xfrm: add an interface to offload policy") Fixes: bf06fcf4be0f ("xfrm: add missed call to delete offloaded policies") Fixes: 982c3aca8bac ("xfrm: delete offloaded policy") Signed-off-by: Jianbo Liu <jianbol@nvidia.com> Reviewed-by: Cosmin Ratiu <cratiu@nvidia.com> Signed-off-by: Leon Romanovsky <leonro@nvidia.com> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>

Some controllers may not be able to reach a bus clock as low as 400 KHz due to a lack of sufficient divisors. In these cases, the SD card slot becomes non-functional as Linux continuously attempts to set the bus clock to 400 KHz. If the controller is incapable of getting that low, set its minimum frequency instead. While this may eliminate some SD cards, it allows those capable of operating at the controller's minimum frequency to be used.

As it turns out, clearing the BSS was not the right fix for the issue that was ultimately fixed by commit decd347c2a75 ("x86/efistub: Reinstate soft limit for initrd loading"), and given that the Windows EFI loader becomes very unhappy when entered with garbage in BSS, this is one thing that x86 PC EFI implementations can be expected to get right.

2024-07-08block: add a bvec_phys helperChristoph Hellwig
Get callers out of poking into bvec internals a bit more. Not a huge win right now, but with the proposed new DMA mapping API we might end up with a lot more of this otherwise.

2024-07-07perf dsos: When adding a dso into sorted dsos maintain the sort orderIan Rogers
dsos__add would add at the end of the dso array possibly requiring a later find to re-sort the array. Patterns of find then add were becoming O(n*log n) due to the sorts. Change the add routine to be O(n) rather than O(1) but to maintain the sorted-ness of the dsos array so that later finds don't need the O(n*log n) sort.

2024-07-07vfs: link_path_walk: move more of the name hashing into hash_name()Linus Torvalds
This avoids having to return the length of the component entirely by just doing all of the name processing in hash_name(). We can just return the end of the path component, and a flag for the DOT and DOTDOT cases. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2024-07-07vfs: link_path_walk: improve may_lookup() code generationLinus Torvalds
Instead of having separate calls to 'inode_permission()' depending on whether we're in RCU lookup or not, just share the first call. Note that the initial "conditional" on LOOKUP_RCU really turns into just a "convert the LOOKUP_RCU bit in the nameidata into the MAY_NOT_BLOCK bit in the argument", which is just a trivial bitwise and and shift operation. So the initial conditional goes away entirely, and then the likely case is that it will succeed independently of us being in RCU lookup or not, and the possible "we may need to fall out of RCU and redo it all" fixups that are needed afterwards all go in the unlikely path. [ This also marks 'nd' restrict, because that means that the compiler can know that there is no other alias, and can cache the LOOKUP_RCU value over the call to inode_permission(). ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2024-07-07cpufreq/amd-pstate: Fix the scaling_max_freq setting on shared memory CPPC ↵Dhananjay Ugwekar
systems On shared memory CPPC systems, with amd_pstate=active mode, the change in scaling_max_freq doesn't get written to the shared memory region. Due to this, the writes to the scaling_max_freq sysfs file don't take effect. Fix this by propagating the scaling_max_freq changes to the shared memory region.
