2012-11-21ARM: clps711x: autcpu12: Special driver for handling NAND memory is removedAlexander Shiyan

2012-11-21ARM: clps711x: Add FIQ interrupt handlingAlexander Shiyan
CLPS711X-target CPU can have a several FIQ interrupts. With this patch we adds handling for a one which will be used for ALSA PCM later. Since FIQ have a separate handler we only add "mask" and "unmask" calls which will used for enable/disable_irq functions.

2012-10-14x86, boot: Explicitly include autoconf.h for hostprogsMatt Fleming
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)

2012-10-13ARM: config: sort select statements alphanumericallyRussell King
As suggested by Andrew Morton: This is a pet peeve of mine. Any time there's a long list of items (header file inclusions, kconfig entries, array initalisers, etc) and someone wants to add a new item, they *always* go and stick it at the end of the list. Guys, don't do this. Either put the new item into a randomly-chosen position or, probably better, alphanumerically sort the list. lets sort all our select statements alphanumerically. This commit was created by the following perl: while (<>) { while (/\\\s*$/) { $_ .= <>; } undef %selects if /^\s*config\s+/; if (/^\s+select\s+(\w+).*/) { if (defined($selects{$1})) { if ($selects{$1} eq $_) { print STDERR "Warning: removing duplicated $1 entry\n"; } else { print STDERR "Error: $1 differently selected\n". "\tOld: $selects{$1}\n". "\tNew: $_\n"; exit 1; } } $selects{$1} = $_; next; } if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or /^endif/ or /^endchoice/)) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } undef %selects; } print; } if (%selects) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } } It found two duplicates: Warning: removing duplicated S5P_SETUP_MIPIPHY entry Warning: removing duplicated HARDIRQS_SW_RESEND entry and they are identical duplicates, hence the shrinkage in the diffstat of two lines.

2012-10-12vfs: define struct filename and have getname() return itJeff Layton
getname() is intended to copy pathname strings from userspace into a kernel buffer. The result is just a string in kernel space. It would however be quite helpful to be able to attach some ancillary info to the string. For instance, we could attach some audit-related info to reduce the amount of audit-related processing needed. When auditing is enabled, we could also call getname() on the string more than once and not need to recopy it from userspace. This patchset converts the getname()/putname() interfaces to return a struct instead of a string. For now, the struct just tracks the string in kernel space and the original userland pointer for it. Later, we'll add other information to the struct as it becomes convenient. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen Pull Xen fixes from Konrad Rzeszutek Wilk: "This has four bug-fixes and one tiny feature that I forgot to put initially in my tree due to oversight. The feature is for kdump kernels to speed up the /proc/vmcore reading. There is a ram_is_pfn helper function that the different platforms can register for. We are now doing that. The bug-fixes cover some embarrassing struct pv_cpu_ops variables being set to NULL on Xen (but not baremetal). We had a similar issue in the past with {write|read}_msr_safe and this fills the three missing ones. The other bug-fix is to make the console output (hvc) be capable of dealing with misbehaving backends and not fall flat on its face. Lastly, a quirk for older XenBus implementations that came with an ancient v3.4 hypervisor (so RHEL5 based) - reading of certain non-existent attributes just hangs the guest during bootup - so we take precaution of not doing that on such older installations. Feature: - Register a pfn_is_ram helper to speed up reading of /proc/vmcore. Bug-fixes: - Three pvops call for Xen were undefined causing BUG_ONs. - Add a quirk so that the shutdown watches (used by kdump) are not used with older Xen (3.4). - Fix ungraceful state transition for the HVC console." * tag 'stable/for-linus-3.7-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen/pv-on-hvm kexec: add quirk for Xen 3.4 and shutdown watches. xen/bootup: allow {read|write}_cr8 pvops call. xen/bootup: allow read_tscp call for Xen PV guests. xen pv-on-hvm: add pfn_is_ram helper for kdump xen/hvc: handle backend CLOSED without CLOSING
