If there are any errors in stm32_exti_host_init() then it leads to a
NULL dereference in the callers. The function should clean up after
itself.

When compiling bmips with SMP disabled, the build fails with:
drivers/irqchip/irq-bcm7038-l1.o: In function `bcm7038_l1_cpu_offline':
drivers/irqchip/irq-bcm7038-l1.c:242: undefined reference to `irq_set_affinity_locked'
make[5]: *** [vmlinux] Error 1
Fix this by adding and setting bcm7038_l1_cpu_offline only when actually
compiling for SMP. It wouldn't have been used anyway, as it requires
CPU_HOTPLUG, which in turn requires SMP.

Allocating a minimum of 32 LPIs per PCI device, let's reduce it to be just 1, as most devices do not need that many interrupts. We still have to special-case DevID 0, as there is plenty of broken HW around where the PCI RID is not presented as a DevID to the ITS, and all the devices are presented as DevID 0. In this case, we keep the 32 minimal allocation. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>

A recent extension to the GIC architecture allows a hypervisor to arbitrarily reduce the number of LPIs available to a guest, no matter what the GIC says about the valid range of IntIDs.

Instead of exposing the GIC distributor IntID field in the rdist structure that is passed to the ITS, let's replace it with a copy of the whole GICD_TYPER register. We are going to need some of this information at a later time. No functionnal change. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>

As we used to represent the LPI range using a bitmap, we were reducing the number of LPIs to at most 64k in order to preserve memory. With our new allocator, there is no such need, as dealing with 2^16 or 2^32 LPIs takes the same amount of memory. So let's use the number of IntID bits reported by the GIC instead of an arbitrary limit. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>

Our current LPI allocator relies on a bitmap, each bit representing a chunk of 32 LPIs, meaning that each device gets allocated LPIs in multiple of 32. It served us well so far, but new use cases now require much more finer grain allocations, down the the individual LPI. Given the size of the IntID space (up to 32bit), it isn't practical to continue using a bitmap, so let's use a different data structure altogether. We switch to a list, where each element represent a contiguous range of LPIs. On allocation, we simply grab the first group big enough to satisfy the allocation, and substract what we need from it. If the group becomes empty, we just remove it. On freeing interrupts, we insert a new group of interrupt in the list, sort it and fuse the adjacent groups. This makes freeing interrupt much more expensive than allocating them (an unusual behaviour), but that's fine as long as we consider that freeing interrupts is an extremely rare event. We still allocate interrupts in blocks of 32 for the time being, but subsequent patches will relax this. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>

ReiserFS prepares log messages into a 1024-byte buffer with no bounds
checks. Long messages, such as the "unknown mount option" warning when
userspace passes a crafted mount options string, overflow this buffer.
This causes KASAN to report a global-out-of-bounds write.
Fix it by truncating messages to the buffer size.

There is no reason to bug on that though. do_brk_flags already aligns the length properly so the mapping is expanded as it should. All we need is to tell mm_populate about it. Besides that there is absolutely no reason to to bug_on in the first place. The worst thing that could happen is that the last page wouldn't get populated and that is far from putting system into an inconsistent state. Fix the issue by moving the length sanitization code from do_brk_flags up to vm_brk_flags. The only other caller of do_brk_flags is brk syscall entry and it makes sure to provide the proper length so t here is no need for sanitation and so we can use do_brk_flags without it. Also remove the bogus BUG_ONs.

Mike Rapoport is converting architectures from bootmem to nobootmem allocator. While doing so for m68k Geert has noticed that he gets a scary looking warning: WARNING: CPU: 0 PID: 0 at mm/memblock.c:230 memblock_find_in_range_node+0x11c/0x1be memblock: bottom-up allocation failed, memory hotunplug may be affected Modules linked in: CPU: 0 PID: 0 Comm: swapper Not tainted 4.18.0-rc3-atari-01343-gf2fb5f2e09a97a3c-dirty #7 Call Trace: __warn+0xa8/0xc2 kernel_pg_dir+0x0/0x1000 netdev_lower_get_next+0x2/0x22 warn_slowpath_fmt+0x2e/0x36 memblock_find_in_range_node+0x11c/0x1be memblock_find_in_range_node+0x11c/0x1be memblock_find_in_range_node+0x0/0x1be vprintk_func+0x66/0x6e memblock_virt_alloc_internal+0xd0/0x156 netdev_lower_get_next+0x2/0x22 netdev_lower_get_next+0x2/0x22 kernel_pg_dir+0x0/0x1000 memblock_virt_alloc_try_nid_nopanic+0x58/0x7a netdev_lower_get_next+0x2/0x22 kernel_pg_dir+0x0/0x1000 kernel_pg_dir+0x0/0x1000 EXPTBL+0x234/0x400 EXPTBL+0x234/0x400 alloc_node_mem_map+0x4a/0x66 netdev_lower_get_next+0x2/0x22 free_area_init_node+0xe2/0x29e EXPTBL+0x234/0x400 paging_init+0x430/0x462 kernel_pg_dir+0x0/0x1000 printk+0x0/0x1a EXPTBL+0x234/0x400 setup_arch+0x1b8/0x22c start_kernel+0x4a/0x40a _sinittext+0x344/0x9e8 The warning is basically saying that a top-down allocation can break memory hotremove because memblock allocation is not movable. But m68k doesn't even support MEMORY_HOTREMOVE so there is no point to warn about it. Make the warning conditional only to configurations that care.

- Build the kernel without the fix
- Add some flag to the purgatories KBUILD_CFLAGS,I used
-fno-asynchronous-unwind-tables
- Re-build the kernel
When you look at makes output you see that sha256.o is not re-build in the
last step. Also readelf -S still shows the .eh_frame section for
sha256.o.
With the fix sha256.o is rebuilt in the last step.
Without FORCE make does not detect changes only made to the command line
options. So object files might not be re-built even when they should be.
Fix this by adding FORCE where it is missing.

In my testing, the second mount will fail after umounting successfully.
The reason is that we put refcount of trans_mod in the correct case
rather than the error case in parse_opts() at last. That will cause the
refcount decrease to -1, and when we try to get trans_mod again in
try_module_get(), we could only increase refcount to 0 which will cause
failure as follows:
parse_opts
v9fs_get_trans_by_name
try_module_get : return NULL to caller which cause error
So we should put refcount of trans_mod in error case.

The mmu_gather APIs keep track of the invalidated address range including the span covered by invalidated page table pages. Ranges covered by page tables but not ptes (and therefore no TLBs) still need to be invalidated because some architectures (x86) can cache intermediate page table entries, and invalidate those with normal TLB invalidation instructions to be almost-backward-compatible. Architectures which don't cache intermediate page table entries, or which invalidate these caches separately from TLB invalidation, do not require TLB invalidation range expanded over page tables. Allow architectures to supply their own p??_free_tlb functions, which can avoid the __tlb_adjust_range.

The autofs subsystem does not check that the "path" parameter is present for all cases where it is required when it is passed in via the "param" struct. In particular it isn't checked for the AUTOFS_DEV_IOCTL_OPENMOUNT_CMD ioctl command. To solve it, modify validate_dev_ioctl(function to check that a path has been provided for ioctl commands that require it.

KVM guests on s390 can notify the host of unused pages. This can result in pte_unused callbacks to be true for KVM guest memory. If a page is unused (checked with pte_unused) we might drop this page instead of paging it. This can have side-effects on userfaultd, when the page in question was already migrated: The next access of that page will trigger a fault and a user fault instead of faulting in a new and empty zero page. As QEMU does not expect a userfault on an already migrated page this migration will fail. The most straightforward solution is to ignore the pte_unused hint if a userfault context is active for this VMA.

Setting pv_irq_ops for Xen PV domains should be done as early as possible in order to support e.g. very early printk() usage. The same applies to xen_vcpu_info_reset(0), as it is needed for the pv irq ops. Move the call of xen_setup_machphys_mapping() after initializing the pv functions as it contains a WARN_ON(), too. Remove the no longer necessary conditional in xen_init_irq_ops() from PVH V1 times to make clear this is a PV only function.

Currently ftrace displays data in trace output like so:
_-----=> irqs-off
/ _----=> need-resched
| / _---=> hardirq/softirq
|| / _--=> preempt-depth
||| / delay
TASK-PID CPU TGID |||| TIMESTAMP FUNCTION
| | | | |||| | |
bash-1091 [000] ( 1091) d..2 28.313544: sched_switch:
However Android's trace visualization tools expect a slightly different
format due to an out-of-tree patch patch that was been carried for a
decade, notice that the TGID and CPU fields are reversed:
_-----=> irqs-off
/ _----=> need-resched
| / _---=> hardirq/softirq
|| / _--=> preempt-depth
||| / delay
TASK-PID TGID CPU |||| TIMESTAMP FUNCTION
| | | | |||| | |
bash-1091 ( 1091) [002] d..2 64.965177: sched_switch:
From kernel v4.13 onwards, during which TGID was introduced, tracing
with systrace on all Android kernels will break (most Android kernels
have been on 4.9 with Android patches, so this issues hasn't been seen
yet). From v4.13 onwards things will break.
The chrome browser's tracing tools also embed the systrace viewer which
uses the legacy TGID format and updates to that are known to be
difficult to make.
Considering this, I suggest we make this change to the upstream kernel
and backport it to all Android kernels. I believe this feature is merged
recently enough into the upstream kernel that it shouldn't be a problem.
Also logically, IMO it makes more sense to group the TGID with the
TASK-PID and the CPU after these.

I2C clients may misunderstand recovery pulses if they can't read SDA to bail out early. In the worst case, as a write operation. To avoid that and if we can write SDA, try to send STOP to avoid the misinterpretation.
