The PB1550 is more or less a DB1550 without the PCI IDE controller, a more complicated (read: configurable) Flash setup and some other minor changes. Like the DB1550 it can be automatically detected by reading the CPLD ID register bits. This patch adds PB1550 detection and setup to the DB1550 code. Signed-off-by:

The #ifdef for CONFIG_HW_PERF_EVENTS is not needed because the Makefile will only compile the module if this config option is set. This means that the code under #else would never be compiled. This may have been done to leave the original broken code around for reference, but the FIXME comment above the code already shows the broken code. Signed-off-by:

Change the indicator from 0xffffffff in the "event_id" member to zero in the "cntr_mask" member. This removes the need to initialize entries that are unsupported. This also solves a problem where the number of entries in the table was increased based on a globel enum used for all platforms, but the new unsupported entries were not added for mips. This was leaving new table entries of all zeros that we not marked UNSUPPORTED. Signed-off-by:

We can save an instruction in the TLB Refill path for kernel mappings by aligning swapper_pg_dir on a 64K boundary. The address of swapper_pg_dir can be generated with a single LUI instead of LUI/{D}ADDUI. The alignment of __init_end is bumped up to 64K so there are no holes between it and swapper_pg_dir, which is placed at the very beginning of .bss. The alignment of invalid_pmd_table and invalid_pte_table can be relaxed to PAGE_SIZE. We do this by using __page_aligned_bss, which has the added benefit of eliminating alignment holes in .bss.

I've maintained this patch, originally from Thiemo Seufer in 2004, for a really long time, but I think it's time for it to get a look at for possible inclusion. I have had no problems with it across various SGI systems over the years. To quote the post here: http://www.linux-mips.org/archives/linux-mips/2004-12/msg00000.html "the atomic functions use so far memory references for the inline assembler to access the semaphore. This can lead to additional instructions in the ll/sc loop, because newer compilers don't expand the memory reference any more but leave it to the assembler. The appended patch uses registers instead, and makes the ll/sc arguments more explicit. In some cases it will lead also to better register scheduling because the register isn't bound to an output any more." Signed-off-by:

Pull i2c-embedded changes from Wolfram Sang: "The changes for i2c-embedded include: - massive rework of the omap driver - massive rework of the at91 driver. In fact, the old driver gets removed; I am okay with this approach since the old driver was depending on BROKEN and its limitations made it practically unusable, so people used bitbanging instead. But even if there are users, there is no platform_data or module parameter which would need to be converted. It is just another driver doing I2C transfers, just way better. Modifications of arch/arm/at91 related files have proper acks from the maintainer. - new driver for R-Car I2C - devicetree and generic_clock conversions and fixes - usual driver fixes and changes. The rework patches have come a long way and lots of people have been involved in creating/testing them. Most patches have been in linux-next at least since 3.6-rc5. A few have been added in the last week, I have to admit. An unexpected (but welcome :)) peak in private life is the cause for that. The "late" patches shouldn't cause any merge conflicts and I will have a special eye on them during the stabilization phase. This is an exception and I want to have the patches in place properly in time again for the next kernels." * 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux: (44 commits) MXS: Implement DMA support into mxs-i2c i2c: add Renesas R-Car I2C driver i2c: s3c2410: use clk_prepare_enable and clk_disable_unprepare ARM: OMAP: convert I2C driver to PM QoS for MPU latency constraints i2c: nomadik: Add Device Tree support to the Nomadik I2C driver i2c: algo: pca: Fix chip reset function for PCA9665 i2c: mpc: Wait for STOP to hit the bus i2c: davinci: preparation for switch to common clock framework omap-i2c: fix incorrect log message when using a device tree i2c: omap: sanitize exit path i2c: omap: switch over to autosuspend API i2c: omap: remove unnecessary pm_runtime_suspended check i2c: omap: switch to threaded IRQ support i2c: omap: remove redundant status read i2c: omap: get rid of the "complete" label i2c: omap: resize fifos before each message i2c: omap: simplify IRQ exit path i2c: omap: always return IRQ_HANDLED i2c: omap: simplify errata check i2c: omap: bus: add a receiver flag ...

In autofs4_d_automount(), if a mount fail occurs the AUTOFS_INF_PENDING mount pending flag is not cleared. One effect of this is when using the "browse" option, directory entry attributes show up with all "?"s due to the incorrect callback and subsequent failure return (when in fact no callback should be made).

Commit 6b8029fa ("rtc: kconfig: remove unnecessary dependencies") removed various 'depends on RTC_CLASS' dependencies but also removed a few 'default RTC_CLASS' statements, which actually changed default behavior. This resulted in the various RTC interfaces (sysfs, proc, dev) all being disabled by default, even when RTC_CLASS is enabled: # CONFIG_RTC_INTF_SYSFS is not set # CONFIG_RTC_INTF_PROC is not set # CONFIG_RTC_INTF_DEV is not set which is different from previous behavior (all of these where enabled.) To fix, add back the 'default RTC_CLASS' statments to each of the RTC_INTF_* options. I noticed this because some RTC tests started failing on my TI OMAP platforms because /dev/rtc0 was not present anymore, even though the driver was present and RTC_CLASS was enabled. Signed-off-by:

The virq_disabled flag tracks the userspace view of INTx masking across interrupt mode changes, but we're not consistently applying this to the interrupt and masking handler notion of the device. Currently if the user sets DisINTx while in MSI or MSIX mode, then returns to INTx mode (ex. rebooting a qemu guest), the hardware has DisINTx+, but the management of INTx thinks it's enabled, making it impossible to actually clear DisINTx. Fix this by updating the handler state when INTx is re-enabled. Cc: stable@vger.kernel.org Signed-off-by:
