33343723cf pcmcia: cs_internal.h is internal
cs_internal.h is meant for definitions internal to the PCMCIA core modules.
It must not be included by PCMCIA socket drivers or by PCMCIA device drivers.

79ba675727 pcmcia: use dev_printk for cs_error()
Use dev_printk() in cs_error()-based error reporting. While this
function-turned-macro will hopefully go away soon, using dev_printk
simplifies the code much.

9c8b7965f5 pcmcia: remove CS_ error codes alltogether
Remoe the CS_ error codes. Drivers are expected to use default
error definitions (errno.h etc.).

Only one CS_ error code -- CS_IN_USE -- is used internally by the
(deprecated) pcmcia-cs userspace package. Therefore, keep this one
around so that it still compiles.

635d19bea0 pcmcia: deprecate CS_NO_MORE_ITEMS
CS_NO_MORE_ITEMS is returned by the CIS tuple reading and parsing code if
the end of a tuple chain is reached. As at least one PCMCIA driver relies
on matching this return value, replace it with -ENOSPC which is now
uniquely used for this purpose within the in-kernel pcmcia subsystem.

9b79022ca9 Fix 'get_user_pages_fast()' with non-page-aligned start address
Alexey Dobriyan reported trouble with LTP with the new fast-gup code,
and Johannes Weiner debugged it to non-page-aligned addresses, where the
new get_user_pages_fast() code would do all the wrong things, including
just traversing past the end of the requested area due to 'addr' never
matching 'end' exactly.

This is not a pretty fix, and we may actually want to move the alignment
into generic code, leaving just the core code per-arch, but Alexey
verified that the vmsplice01 LTP test doesn't crash with this.

8c79873da0 lguest: turn Waker into a thread, not a process
lguest uses a Waker process to break it out of the kernel (ie.
actually running the guest) when file descriptor needs attention.

Changing this from a process to a thread somewhat simplifies things:
it can directly access the fd_set of things to watch.  More
importantly, it means that the Waker can see Guest memory correctly,
so /dev/vring file descriptors will work as anticipated (the
alternative is to actually mmap MAP_SHARED, but you can't do that with
/dev/zero).
