      mtd: fix build error in m25p80.c · 40847437
      由 Andres Salomon 提交于 
      While building an x86 distro kernel, I hit the following:

Kernel: arch/x86/boot/bzImage is ready  (#7)
ERROR: "of_mtd_parse_partitions" [drivers/mtd/devices/m25p80.ko]
undefined!

of_mtd_parse_partitions is defined with MTD_OF_PARTS, and that's only
built on PPC and microblaze.  The code in question should be wrapped w/
a stricter #ifdef.

      mtd: Remove redundant mutex from mtd_blkdevs.c · 8cc9de3e
      由 David Woodhouse 提交于 
      In commit 2a48fc0a ('block: autoconvert
trivial BKL users to private mutex'), Arnd replaced the BKL usage with a
mutex. However, Maxim has already provided a better fix in commit
480792b7 ('mtd: blktrans: kill BKL'),
which was simply to remove the BKL without replacing it — since he'd
already made it do all necessary locking for itself.

		tr->name, tr->major, ret);

Above code will return fail when register_blkdev return allocated major number.

      This code is stalled, with no one working on it anymore, and the main
msm code is now going through the proper channels to get merged
correctly.

So remove it as it contains a number of kernel information leaks and it
is doubtful if it even still builds anymore.

      For the SD8686, we cannot rely on the scratch register to read the firmware
load status, because the same register is used for storing RX packet length.
Broaden the check to account for this.

The module can now be unloaded/reloaded successfully.

Based on the implementation from libertas_tf.

      kgdbts: prevent re-entry to kgdbts before it unregisters · 4dacd5c0
      由 Dongdong Deng 提交于 
      The "kgdb_connected" variable of debug_core just indicates whether or
not kgdbts is connected to the debug_core.  It does not completely
prevent a script from trying invoke kgdbts again and possibly crashing
the system (see Call Trace below).

The configured variable in kgtbts can be used instead of
kgdb_connected instead of kgdb_connected. The cleanup_kgdbts() can
also be removed because there is no possible way to build kgdbts as a
kernel module that you could unload with rmmod.

      USB: Add EHCI and OHCH glue for OCTEON II SOCs. · 1643accd
      由 David Daney 提交于 
      The OCTEON II SOC has USB EHCI and OHCI controllers connected directly
to the internal I/O bus.  This patch adds the necessary 'glue' logic
to allow ehci-hcd and ohci-hcd drivers to work on OCTEON II.

The OCTEON normally runs big-endian, and the ehci/ohci internal
registers have host endianness, so we need to select
USB_EHCI_BIG_ENDIAN_MMIO.

The ehci and ohci blocks share a common clocking and PHY
infrastructure.  Initialization of the host controller and PHY clocks
is common between the two and is factored out into the
octeon2-common.c file.

Setting of USB_ARCH_HAS_OHCI and USB_ARCH_HAS_EHCI is done in
arch/mips/Kconfig in a following patch.
