Pull ARM updates from Russell King: "Included in this series are: 1. BE8 (modern big endian) changes for ARM from Ben Dooks 2. big.Little support from Nicolas Pitre and Dave Martin 3. support for LPAE systems with all system memory above 4GB 4. Perf updates from Will Deacon 5. Additional prefetching and other performance improvements from Will. 6. Neon-optimised AES implementation fro Ard. 7. A number of smaller fixes scattered around the place. There is a rather horrid merge conflict in tools/perf - I was never notified of the conflict because it originally occurred between Will's tree and other stuff. Consequently I have a resolution which Will forwarded me, which I'll forward on immediately after sending this mail. The other notable thing is I'm expecting some build breakage in the crypto stuff on ARM only with Ard's AES patches. These were merged into a stable git branch which others had already pulled, so there's little I can do about this. The problem is caused because these patches have a dependency on some code in the crypto git tree - I tried requesting a branch I can pull to resolve these, and all I got each time from the crypto people was "we'll revert our patches then" which would only make things worse since I still don't have the dependent patches. I've no idea what's going on there or how to resolve that, and since I can't split these patches from the rest of this pull request, I'm rather stuck with pushing this as-is or reverting Ard's patches. Since it should "come out in the wash" I've left them in - the only build problems they seem to cause at the moment are with randconfigs, and since it's a new feature anyway. However, if by -rc1 the dependencies aren't in, I think it'd be best to revert Ard's patches" I resolved the perf conflict roughly as per the patch sent by Russell, but there may be some differences. Any errors are likely mine.

Fix regression introduced by commit d2323cf773 ("onewire: w1-gpio: add ext_pullup_enable pin in platform data") which added a gpio entry to the platform data, but did not add the required initialisers to the board files using it. Consequently, the driver would request gpio 0 at probe, which could break other uses of the corresponding pin. On AT91 requesting gpio 0 changes the pin muxing for PIOA0, which, for instance, breaks SPI0 on at91sam9g20.

2013-01-14ARM: use clockevents_config_and_register() where possibleShawn Guo1-9/+2
The clockevent core is able to figure out the best mult and shift, calculate min_delta_ns and max_delta_ns, with the necessary info passed into clockevents_config_and_register(). Use this combined configure and register function where possible to make the codes less error prone and gain some positive diff stat.

2012-12-24ARM: delete struct sys_timerStephen Warren15-35/+20
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2012-11-22IXP4xx: use __iomem for MMIOArnd Bergmann2-8/+8
The ixp4xx queue manager uses "const struct qmgr_regs __iomem *" as the type for a pointer that is passed to __raw_writel, which is not allowed because of the const-ness. Dropping the 'const' keyword fixes the problem. While we're here, let's also drop the useless type cast. Without this patch, building ixp4xx_defconfig results in: In file included from arch/arm/mach-ixp4xx/ixp4xx_qmgr.c:15:0: arch/arm/mach-ixp4xx/include/mach/qmgr.h: In function 'qmgr_put_entry': arch/arm/mach-ixp4xx/include/mach/qmgr.h:96:2: warning: passing argument 2 of '__raw_writel' discards 'const' qualifier from pointer target type [enabled by default] arch/arm/include/asm/io.h:88:91: note: expected 'volatile void *' but argument is of type 'const u32 *' In file included from drivers/net/ethernet/xscale/ixp4xx_eth.c:41:0: arch/arm/mach-ixp4xx/include/mach/qmgr.h: In function 'qmgr_put_entry': arch/arm/mach-ixp4xx/include/mach/qmgr.h:96:2: warning: passing argument 2 of '__raw_writel' discards 'const' qualifier from pointer target type [enabled by default] arch/arm/include/asm/io.h:88:91: note: expected 'volatile void *' but argument is of type 'const u32 *' arch/arm/mach-ixp4xx/ixp4xx_qmgr.c: In function 'qmgr_set_irq': arch/arm/mach-ixp4xx/ixp4xx_qmgr.c:41:9: warning: passing argument 2 of '__raw_writel' discards 'const' qualifier from pointer target type [enabled by default] arch/arm/include/asm/io.h:88:91: note: expected 'volatile void *' but argument is of type 'const u32 *' Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl>

2012-10-13ARM: config: sort select statements alphanumericallyRussell King1-1/+1
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.

It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while.
