2012-07-30Merge branch 'akpm' (Andrew's patch-bomb)Linus Torvalds
Merge Andrew's first set of patches: "Non-MM patches: - lots of misc bits - tree-wide have_clk() cleanups - quite a lot of printk tweaks. I draw your attention to "printk: convert the format for KERN_<LEVEL> to a 2 byte pattern" which looks a bit scary. But afaict it's solid. - backlight updates - lib/ feature work (notably the addition and use of memweight()) - checkpatch updates - rtc updates - nilfs updates - fatfs updates (partial, still waiting for acks) - kdump, proc, fork, IPC, sysctl, taskstats, pps, etc - new fault-injection feature work" * Merge emailed patches from Andrew Morton <akpm@linux-foundation.org>: (128 commits) drivers/misc/lkdtm.c: fix missing allocation failure check lib/scatterlist: do not re-write gfp_flags in __sg_alloc_table() fault-injection: add tool to run command with failslab or fail_page_alloc fault-injection: add selftests for cpu and memory hotplug powerpc: pSeries reconfig notifier error injection module memory: memory notifier error injection module PM: PM notifier error injection module cpu: rewrite cpu-notifier-error-inject module fault-injection: notifier error injection c/r: fcntl: add F_GETOWNER_UIDS option resource: make sure requested range is included in the root range include/linux/aio.h: cpp->C conversions fs: cachefiles: add support for large files in filesystem caching pps: return PTR_ERR on error in device_create taskstats: check nla_reserve() return sysctl: suppress kmemleak messages ipc: use Kconfig options for __ARCH_WANT_[COMPAT_]IPC_PARSE_VERSION ipc: compat: use signed size_t types for msgsnd and msgrcv ipc: allow compat IPC version field parsing if !ARCH_WANT_OLD_COMPAT_IPC ipc: add COMPAT_SHMLBA support ...

2012-07-30drivers/rtc/rtc-r9701.c: check that r9701_set_datetime() succeededAndrew Morton
When the driver detects that the clock time is invalid, it attempts to write a sane time into the hardware. We curently assume that everything is OK if those writes succeeded. But it is better to re-read the time from the hardware to ensure that the new settings got there OK.

2012-07-30rtc: pl031: fix up IRQ flagsMattias Wallin
The pl031 interrupt is shared between the timer part and the clockwatch part of the same HW block on the ux500, so mark it IRQF_SHARED on this variant. This patch also adds the IRQF_NO_SUSPEND flag to the rtc irq on all variants as we don't want this pretty important IRQ to be disabled in suspend.

firmware_map_add_hotplug() There are two ways to create /sys/firmware/memmap/X sysfs: - firmware_map_add_early When the system starts, it is calledd from e820_reserve_resources() - firmware_map_add_hotplug When the memory is hot plugged, it is called from add_memory() But these functions are called without unifying value of end argument as below: - end argument of firmware_map_add_early() : start + size - 1 - end argument of firmware_map_add_hogplug() : start + size The patch unifies them to "start + size". Even if applying the patch, /sys/firmware/memmap/X/end file content does not change.

2012-07-30i2c/i2c-pxa: remove conditional compilation of clk codeViresh Kumar
With addition of dummy clk_*() calls for non CONFIG_HAVE_CLK cases in clk.h, there is no need to have clk code enclosed in #ifdef CONFIG_HAVE_CLK, #endif macros. pxa i2c also has these dummy macros defined locally. Remove them as they aren't required anymore.

menu "Common Clock Framework" has "depends on COMMON_CLK" and so configs defined within menu don't require these "depends on COMMON_CLK again".

2012-07-30pcdp: use early_ioremap/early_iounmap to access pcdp tableGreg Pearson
efi_setup_pcdp_console() is called during boot to parse the HCDP/PCDP EFI system table and setup an early console for printk output. The routine uses ioremap/iounmap to setup access to the HCDP/PCDP table information. The call to ioremap is happening early in the boot process which leads to a panic on x86_64 systems: panic+0x01ca do_exit+0x043c oops_end+0x00a7 no_context+0x0119 __bad_area_nosemaphore+0x0138 bad_area_nosemaphore+0x000e do_page_fault+0x0321 page_fault+0x0020 reserve_memtype+0x02a1 __ioremap_caller+0x0123 ioremap_nocache+0x0012 efi_setup_pcdp_console+0x002b setup_arch+0x03a9 start_kernel+0x00d4 x86_64_start_reservations+0x012c x86_64_start_kernel+0x00fe This replaces the calls to ioremap/iounmap in efi_setup_pcdp_console() with calls to early_ioremap/early_iounmap which can be called during early boot. This patch was tested on an x86_64 prototype system which uses the HCDP/PCDP table for early console setup.

Fix up mostly trivial conflicts, with the exception of drivers/usb/host/ehci-omap.c in particular, which had some re-organization of the reset sequence (commit 1a49e2ac9651: "EHCI: centralize controller initialization") that clashed with commit 2761a6394516 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix issues"). In particular, commit 2761a6394516 moved the usb_add_hcd() to the *middle* of the reset sequence, which clashes fairly badly with the reset sequence re-organization (although it could have been done inside the new omap_ehci_init() function).
