2012-10-23arch/tile: eliminate pt_regs trampolines for syscallsChris Metcalf10-57/+39
Using the new current_pt_regs() model, we can remove some trampolines from assembly code and call directly to the C syscall implementations. rt_sigreturn() and clone() still need some assembly wrapping, but no longer are passed a pt_regs pointer. sigaltstack() and the tilepro-specific cmpxchg_badaddr() syscalls are now just straight C.

2012-10-14parisc: optimizations in copy_thread() and friendsAl Viro2-87/+27
* in user thread case the registers had been copied as part of task_struct already; no need to do it in copy_thread(). * no need to store kernel stack pointer into regs->r21; we know its offset anyway. * no need to clobber r3 in sys_fork_wrapper and friends - r28 will do just as well and *it* will be overwritten anyway. * no need to mess with storing the return address for child - it should just use syscall_exit. * no need to bother with separate stack frame for sys_clone() - just branch there and be done with that. * no need to bother with wrapper_exit - we need it only on the child_return, so let's just do it there. * use the same ksp for kernel threads and userland ones, while we are at it, and let ret_from_kernel_execve() go through the normal syscall_exit. More straightforward is better here... [fixes from jejb folded] Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-10-14ia64: don't mess with ar_bspstore in kernel_thread()Al Viro1-5/+4
the only thing we use that for is in copy_thread(), where the way we set it will result in rbs_size being 0. Just move that calculating rbs_size and copying rbs to non-kernel-thread side of if (user_mode(regs)) in copy_thread() and set rbs_size to 0 on kernel thread side.

2012-10-14x86, boot: Explicitly include autoconf.h for hostprogsMatt Fleming1-1/+2
The hostprogs need access to the CONFIG_* symbols found in include/generated/autoconf.h. But commit abbf1590de22 ("UAPI: Partition the header include path sets and add uapi/ header directories") replaced $(LINUXINCLUDE) with $(USERINCLUDE) which doesn't contain the necessary include paths. This has the undesirable effect of breaking the EFI boot stub because the #ifdef CONFIG_EFI_STUB code in arch/x86/boot/tools/build.c is never compiled. It should also be noted that because $(USERINCLUDE) isn't exported by the top-level Makefile it's actually empty in arch/x86/boot/Makefile. Cc: H.

Pull ARM update from Russell King: "This is the final round of stuff for ARM, left until the end of the merge window to reduce the number of conflicts. This set contains the ARM part of David Howells UAPI changes, and a fix to the ordering of 'select' statements in ARM Kconfig files (see the appropriate commit for why this happened - thanks to Andrew Morton for pointing out the problem.) I've left this as long as I dare for this window to avoid conflicts, and I regenerated the config patch yesterday, posting it to our mailing list for review and testing. I have several acks which include successful test reports for it. However, today I notice we've got new conflicts with previously unseen code... though that conflict should be trivial (it's my changes vs a one liner.)" * 'late-for-linus' of git://git.linaro.org/people/rmk/linux-arm: ARM: config: make sure that platforms are ordered by option string ARM: config: sort select statements alphanumerically UAPI: (Scripted) Disintegrate arch/arm/include/asm Fix up fairly conflict in arch/arm/Kconfig (the select re-organization vs recent addition of GENERIC_KERNEL_EXECVE)
2012-10-13Merge tag 'disintegrate-main-20121013' of ↵Linus Torvalds584-30367/+32928
git://git.infradead.org/users/dhowells/linux-headers Pull UAPI disintegration for include/linux/{,byteorder/}*.h from David Howells: "The patches contained herein do the following: (1) Remove kernel-only stuff in linux/ppp-comp.h from the UAPI. I checked this with Paul Mackerras before I created the patch and he suggested some extra bits to unexport. (2) Remove linux/blk_types.h entirely from the UAPI as none of it is userspace applicable, and remove from the UAPI that part of linux/fs.h that was the reason for linux/blk_types.h being exported in the first place. I discussed this with Jens Axboe before creating the patch. (3) The big patch of the series to disintegrate include/linux/*.h as a unit. This could be split up, though there would be collisions in moving stuff between the two Kbuild files when the parts are merged as that file is sorted alphabetically rather than being grouped by subsystem. Of this set of headers, 17 files have changed in the UAPI exported region since the 4th and only 8 since the 9th so there isn't much change in this area - as one might expect. It should be pretty obvious and straightforward if it does come to fixing up: stuff in __KERNEL__ guards stays where it is and stuff outside moves to the same file in the include/uapi/linux/ directory. If a new file appears then things get a bit more complicated as the "headers +=" line has to move to include/uapi/linux/Kbuild. Only one new file has appeared since the 9th and I judge this type of event relatively unlikely. (4) A patch to disintegrate include/linux/byteorder/*.h as a unit.
