pcnet32: use pci_set_dma_mask insted of pci_dma_supported
All drivers should be using dma_set_mask / pci_set_dma_mask to try to
set the dma mask instead of just querying it. Without that some iommu
implementations may not work.
pci_dma_supported is removed entirely, but dma_supported stays for
dma_ops implementations for now.
This patch (of 15):
This ensures the dma mask that is supported by the driver is recorded
in the device structure.

fs/binfmt_elf_fdpic.c: provide NOMMU loader for regular ELF binaries
The ELF binary loader in binfmt_elf.c requires an MMU, making it
impossible to use regular ELF binaries on NOMMU archs. However, the FDPIC
ELF loader in binfmt_elf_fdpic.c is fully capable as a loader for plain
ELF, which requires constant displacements between LOAD segments, since it
already supports FDPIC ELF files flagged as needing constant displacement.
This patch adjusts the FDPIC ELF loader to accept non-FDPIC ELF files on
NOMMU archs. They are treated identically to FDPIC ELF files with the
constant-displacement flag bit set, except for personality, which must
match the ABI of the program being loaded; the PER_LINUX_FDPIC personality
controls how the kernel interprets function pointers passed to sigaction.
Files that do not set a stack size requirement explicitly are given a
default stack size (matching the amount of committed stack the normal ELF
loader for MMU archs would give them) rather than being rejected; this is
necessary because plain ELF files generally do not declare stack
requirements in theit program headers.
Only ET_DYN (PIE) format ELF files are supported, since loading at a fixed
virtual address is not possible on NOMMU.
This patch was developed and tested on J2 (SH2-compatible) but should
be usable immediately on all archs where binfmt_elf_fdpic is
available. Moreover, by providing dummy definitions of the
elf_check_fdpic() and elf_check_const_displacement() macros for archs
which lack an FDPIC ABI, it should be possible to enable building of
binfmt_elf_fdpic on all other NOMMU archs and thereby give them ELF
binary support, but I have not yet tested this.
The motivation for using binfmt_elf_fdpic.c rather than adapting
binfmt_elf.c to NOMMU is that the former already has all the necessary
code to work properly on NOMMU and has already received widespread
real-world use and testing. I hope this is not controversial.
I'm not really happy with having to unset the FDPIC_FUNCPTRS
personality bit when loading non-FDPIC ELF. This bit should really
reset automatically on execve, since otherwise, executing non-ELF
binaries (e.g. bFLT) from an FDPIC process will leave the personality
in the wrong state and severely break signal handling. But that's a
separate, existing bug and I don't know the right place to fix it.

For 64-bit arguments, the abs macro casts it to an int which leads to
lost precision and may cause incorrect results. To deal with 64-bit
types abs64 macro has been introduced but still there are places where
abs macro is used incorrectly.
To deal with the problem, expand abs macro such that it operates on s64
type when dealing with 64-bit types while still returning long when
dealing with smaller types.
This fixes one known bug (per John):
The internal clocksteering done for fine-grained error correction uses a
: logarithmic approximation, so any time adjtimex() adjusts the clock
: steering, timekeeping_freqadjust() quickly approximates the correct clock
: frequency over a series of ticks.
:
: Unfortunately, the logic in timekeeping_freqadjust(), introduced in commit
: dc491596f639438 (Rework frequency adjustments to work better w/ nohz),
: used the abs() function with a s64 error value to calculate the size of
: the approximated adjustment to be made.
:
: Per include/linux/kernel.h: "abs() should not be used for 64-bit types
: (s64, u64, long long) - use abs64()".
:
: Thus on 32-bit platforms, this resulted in the clocksteering to take a
: quite dampended random walk trying to converge on the proper frequency,
: which caused the adjustments to be made much slower then intended (most
: easily observed when large adjustments are made).

This patch fixes some bugs and partly cleans up the parisc uapi header

- compat_semid64_ds was wrong and did not take the endianess into
account
- ipc64_perm exported userspace types which broke building userspace
packages on debian (e.g. trinity)
- ipc64_perm needs to use a 32bit mode_t on 64bit kernel
- msqid64_ds and semid64_ds needs unsigned longs for various struct members
- shmid64_ds exported size_t instead of __kernel_size_t
And finally add some compile-time checks for the sizes of those structs
to avoid future breakage.
