There shouldn't be any reason to ever use uncached over writecombine, so just use writecombine for MSM_BO_UNCACHED. Note: userspace never used MSM_BO_UNCACHED anyway Signed-off-by:

irq_hpd interrupt should be handled after dongle plugged in and before dongle unplugged. Hence irq_hpd interrupt is enabled at the end of the plugin handle and disabled at the beginning of unplugged handle. Current irq_hpd with sink_count = 0 is wrongly handled same as the dongle unplugged which tears down the mainlink and disables the phy. This patch fixes this problem by only tearing down the mainlink but keeping phy enabled at irq_hpd with sink_count = 0 handle so that next irq_hpd with sink_count =1 can be handled by setup mainlink only. This patch also set dongle into D3 (power off) state at end of handling irq_hpd with sink_count = 0. Changes in v2: -- add ctrl->phy_Power_count Changes in v3: -- del ctrl->phy_Power_count -- add phy_power_off to dp_ctrl_off_link_stream() Changes in v4: -- return immediately if clock disable failed at dp_ctrl_off_link_stream() Changes in v5: -- set dongle to D3 (power off) state at dp_ctrl_off_link_stream() Changes in v6: -- add Fixes tag Fixes: ea9f337c ("drm/msm/dp: reset dp controller only at boot up and pm_resume") Signed-off-by:

In commit d6995da3 ("hugetlb: use page.private for hugetlb specific page flags") the use of PagePrivate to indicate a reservation count should be restored at free time was changed to the hugetlb specific flag HPageRestoreReserve. Changes to a userfaultfd error path as well as a VM_BUG_ON() in remove_inode_hugepages() were overlooked. Users could see incorrect hugetlb reserve counts if they experience an error with a UFFDIO_COPY operation. Specifically, this would be the result of an unlikely copy_huge_page_from_user error. There is not an increased chance of hitting the VM_BUG_ON.

GENMASK() has an input check which uses __builtin_choose_expr() to enable a compile time sanity check of its inputs if they are known at compile time. However, it turns out that __builtin_constant_p() does not always return a compile time constant [0]. It was thought this problem was fixed with gcc 4.9 [1], but apparently this is not the case [2]. Switch to use __is_constexpr() instead which always returns a compile time constant, regardless of its inputs.

Commit 9bf3bc94 ("watchdog: cleanup handling of false positives") tried to handle a virtual host stopped by the host a more straightforward and cleaner way. But it introduced a risk of false softlockup reports. The virtual host might be stopped at any time, for example between kvm_check_and_clear_guest_paused() and is_softlockup(). As a result, is_softlockup() might read the updated jiffies and detects a softlockup. A solution might be to put back kvm_check_and_clear_guest_paused() after is_softlockup() and detect it. But it would put back the cycle that complicates the logic. In fact, the handling of all the timestamps is not reliable. The code does not guarantee when and how many times the timestamps are read. For example, "period_ts" might be touched anytime also from NMI and re-read in is_softlockup(). It works just by chance. Fix all the problems by making the code even more explicit. 1. Make sure that "now" and "period_ts" timestamps are read only once. They might be changed at anytime by NMI or when the virtual guest is stopped by the host. Note that "now" timestamp does this implicitly because "jiffies" is marked volatile. 2. "now" time must be read first. The state of "period_ts" will decide whether it will be used or the period will get restarted. 3. kvm_check_and_clear_guest_paused() must be called before reading "period_ts". It touches the variable when the guest was stopped. As a result, "now" timestamp is used only when the watchdog was not touched and the guest not stopped in the meantime. "period_ts" is restarted in all other situations. Link: https://lkml.kernel.org/r/YKT55gw+RZfyoFf7@alley Fixes: 9bf3bc94 ("watchdog: cleanup handling of false positives") Signed-off-by:

do_mq_timedreceive calls wq_sleep with a stack local address. The sender (do_mq_timedsend) uses this address to later call pipelined_send. This leads to a very hard to trigger race where a do_mq_timedreceive call might return and leave do_mq_timedsend to rely on an invalid address, causing the following crash: RIP: 0010:wake_q_add_safe+0x13/0x60 Call Trace: __x64_sys_mq_timedsend+0x2a9/0x490 do_syscall_64+0x80/0x680 entry_SYSCALL_64_after_hwframe+0x44/0xa9 RIP: 0033:0x7f5928e40343 The race occurs as: 1. do_mq_timedreceive calls wq_sleep with the address of `struct ext_wait_queue` on function stack (aliased as `ewq_addr` here) - it holds a valid `struct ext_wait_queue *` as long as the stack has not been overwritten. 2. `ewq_addr` gets added to info->e_wait_q[RECV].list in wq_add, and do_mq_timedsend receives it via wq_get_first_waiter(info, RECV) to call __pipelined_op. 3. Sender calls __pipelined_op::smp_store_release(&this->state, STATE_READY). Here is where the race window begins. (`this` is `ewq_addr`.) 4. If the receiver wakes up now in do_mq_timedreceive::wq_sleep, it will see `state == STATE_READY` and break. 5. do_mq_timedreceive returns, and `ewq_addr` is no longer guaranteed to be a `struct ext_wait_queue *` since it was on do_mq_timedreceive's stack. (Although the address may not get overwritten until another function happens to touch it, which means it can persist around for an indefinite time.) 6. do_mq_timedsend::__pipelined_op() still believes `ewq_addr` is a `struct ext_wait_queue *`, and uses it to find a task_struct to pass to the wake_q_add_safe call. In the lucky case where nothing has overwritten `ewq_addr` yet, `ewq_addr->task` is the right task_struct. In the unlucky case, __pipelined_op::wake_q_add_safe gets handed a bogus address as the receiver's task_struct causing the crash. do_mq_timedsend::__pipelined_op() should not dereference `this` after setting STATE_READY, as the receiver counterpart is now free to return. Change __pipelined_op to call wake_q_add_safe on the receiver's task_struct returned by get_task_struct, instead of dereferencing `this` which sits on the receiver's stack. As Manfred pointed out, the race potentially also exists in ipc/msg.c::expunge_all and ipc/sem.c::wake_up_sem_queue_prepare. Fix those in the same way.

While reviewing [1] I came across commit d3378e86 ("mm/gup: check page posion status for coredump.") and noticed that this patch is broken in two ways. First it doesn't really prevent hwpoison pages from being dumped because hwpoison pages can be marked asynchornously at any time after the check. Secondly, and more importantly, the patch introduces a ref count leak because get_dump_page takes a reference on the page which is not released. It also seems that the patch was merged incorrectly because there were follow up changes not included as well as discussions on how to address the underlying problem [2] Therefore revert the original patch.

clang sometimes decides not to inline shuffle_zone(), but it calls a __meminit function.

This is often because shuffle_zone lacks a __meminit annotation or the annotation of __shuffle_zone is wrong. shuffle_free_memory() did not show the same problem in my tests, but it could happen in theory as well, so mark both as __meminit.
