Remove checks for resource size in adjust_bridge_window(). This is
necessary to allow pci_bus_distribute_available_resources() to function
when the kernel parameter "pci=hpmemsize=nn[KMG]" is used to allocate
resources. Because the kernel parameter sets the size of all hotplug
bridges to be the same, there are problems when nested hotplug bridges are
encountered. Fitting a downstream hotplug bridge with size X and normal
bridges with non-zero size Y into parent hotplug bridge with size X is
impossible, and hence the downstream hotplug bridge needs to shrink to fit
into its parent.
Add check for if bridge is extended or shrunken and reflect that in the
call to pci_dbg().
Reset the resource if its new size is zero (if we have run out of a bridge
window resource) to prevent the PCI resource assignment code from
attempting to assign a zero-sized resource.

Change adjust_bridge_window() to set resource size directly instead of

Because additional resource lists are optional resources, any algorithm
that requires guaranteed allocation that uses them cannot be guaranteed to

redundant.

Change pci_bus_distribute_available_resources() to better handle bridges
with different resource alignment requirements.
The arguments io, mmio and mmio_pref represent the start and end
addresses of resource, into which we must fit the current bridge window.
The steps taken by pci_bus_distribute_available_resources():
- For io, mmio and mmio_pref, increase .start to align with the alignment
of the current bridge window (otherwise the current bridge window may
not fit within the available range).
- For io, mmio and mmio_pref, adjust the current bridge window to the
size after the above.
- Count the number of hotplug bridges and normal bridges on this bus.
- If the total number of bridges is one, give that bridge all of the
resources and return.
- If there are no hotplug bridges, return.
- For io, mmio and mmio_pref, increase .start by the amount required for
each bridge resource on the bus for non hotplug bridges, giving extra
room to make up for alignment of those resources.
- For io, mmio and mmio_pref, calculate the resource size per hotplug
bridge which is available after the previous steps.
- For io, mmio and mmio_pref, distribute the resources to each hotplug
bridge, with the sizes calculated above.
The motivation for fixing this is enabling devices that require greater
than 1MB alignment. This fixes the case where the user hot-adds devices
with BAR alignment >1MB and Linux fails to assign resources to it.

These are updates to device drivers and file systems that for some reason
or another were not included in the kernel in the previous y2038 series.
I've gone through all users of time_t again to make sure the kernel is
in a long-term maintainable state, replacing all remaining references
to time_t with safe alternatives.
Some related parts of the series were picked up into the nfsd, xfs,
alsa and v4l2 trees. A final set of patches in linux-mm removes the now
unused time_t/timeval/timespec types and helper functions after all five
branches are merged for linux-5.6, ensuring that no new users get merged.
As a result, linux-5.6, or my backport of the patches to 5.4 [1], should
be the first release that can serve as a base for a 32-bit system designed
to run beyond year 2038, with a few remaining caveats:
- All user space must be compiled with a 64-bit time_t, which will be
supported in the coming musl-1.2 and glibc-2.32 releases, along with
installed kernel headers from linux-5.6 or higher.
- Applications that use the system call interfaces directly need to be
ported to use the time64 syscalls added in linux-5.1 in place of the
existing system calls. This impacts most users of futex() and seccomp()
as well as programming languages that have their own runtime environment
not based on libc.
- Applications that use a private copy of kernel uapi header files or
their contents may need to update to the linux-5.6 version, in
particular for sound/asound.h, xfs/xfs_fs.h, linux/input.h,
linux/elfcore.h, linux/sockios.h, linux/timex.h and linux/can/bcm.h.
- A few remaining interfaces cannot be changed to pass a 64-bit time_t
in a compatible way, so they must be configured to use CLOCK_MONOTONIC
times or (with a y2106 problem) unsigned 32-bit timestamps. Most
importantly this impacts all users of 'struct input_event'.
- All y2038 problems that are present on 64-bit machines also apply to
32-bit machines. In particular this affects file systems with on-disk
timestamps using signed 32-bit seconds: ext4 with ext3-style small
inodes, ext2, xfs (to be fixed soon) and ufs.
