For simple modules that contain a single platform_driver without any additional setup code then ends up being a block of duplicated boilerplate. This patch adds a new macro, module_platform_driver(), which replaces the module_init()/module_exit() registrations with template functions. Signed-off-by:

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a : genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed. Signed-off-by:

Takashi Iwai authored
Commit 4b239f45 ("x86-64, mm: Put early page table high") causes a S4 regression since 2.6.39, namely the machine reboots occasionally at S4 resume. It doesn't happen always, overall rate is about 1/20. But, like other bugs, once when this happens, it continues to happen. This patch fixes the problem by essentially reverting the memory assignment in the older way. Signed-off-by:

Fix memory leak introduced by commit a6e50b40 (dm snapshot: skip reading origin when overwriting complete chunk). When allocating a set of jobs from kc->job_pool, job->master_job must be set (to point to itself) so that the mempool item gets freed when the master_job completes. master_job was introduced by commit c6ea41fb (dm kcopyd: preallocate sub jobs to avoid deadlock) Reported-by:

The ghash_update function passes a pointer to gf128mul_4k_lle which will be NULL if ghash_setkey is not called or if the most recent call to ghash_setkey failed to allocate memory. This causes an oops. Fix this up by returning an error code in the null case. This is trivially triggered from unprivileged userspace through the AF_ALG interface by simply writing to the socket without setting a key. The ghash_final function has a similar issue, but triggering it requires a memory allocation failure in ghash_setkey _after_ at least one successful call to ghash_update.

I don't usually pay much attention to the stale "?

RIP: 0010:[<ffffffff81127b76>] [<ffffffff81127b76>] migration_entry_wait+0x156/0x160 [<ffffffff811016a1>] handle_pte_fault+0xae1/0xaf0 [<ffffffff810feee2>] ? __pte_alloc+0x42/0x120 [<ffffffff8112c26b>] ? do_huge_pmd_anonymous_page+0xab/0x310 [<ffffffff81102a31>] handle_mm_fault+0x181/0x310 [<ffffffff81106097>] ? vma_adjust+0x537/0x570 [<ffffffff81424bed>] do_page_fault+0x11d/0x4e0 [<ffffffff81109a05>] ? do_mremap+0x2d5/0x570 [<ffffffff81421d5f>] page_fault+0x1f/0x30 mremap's down_write of mmap_sem, together with i_mmap_mutex or lock, and pagetable locks, were good enough before page migration (with its requirement that every migration entry be found) came in, and enough while migration always held mmap_sem; but not enough nowadays, when there's memory hotremove and compaction. The danger is that move_ptes() lets a migration entry dodge around behind remove_migration_pte()'s back, so it's in the old location when looking at the new, then in the new location when looking at the old. Either mremap's move_ptes() must additionally take anon_vma lock(), or migration's remove_migration_pte() must stop peeking for is_swap_entry() before it takes pagetable lock. Consensus chooses the latter: we prefer to add overhead to migration than to mremapping, which gets used by JVMs and by exec stack setup. Reported-and-tested-by:

Due to commit 92fc43b4 ("r8169: modify the flow of the hw reset."), rtl8169_hw_reset stomps during driver shutdown on RxConfig bits which are needed for WOL on some versions of the hardware. As these bits were formerly set from the r81{0x, 68}_pll_power_down methods, factor them out for use in the driver shutdown (rtl_shutdown) handler. I favored __rtl8169_get_wol() -hardware state indication- over RTL_FEATURE_WOL as the latter has become a good candidate for removal. Signed-off-by:

The bond->recv_probe is called in bond_handle_frame() when a packet is received, but bond_close() sets it to NULL. So, a panic occurs when both functions work in parallel. Why this happen: After null pointer check of bond->recv_probe, an sk_buff is duplicated and bond->recv_probe is called in bond_handle_frame. So, a panic occurs when bond_close() is called between the check and call of bond->recv_probe. Patch: This patch uses a local function pointer of bond->recv_probe in bond_handle_frame(). So, it can avoid the null pointer dereference. Signed-off-by:
