119537c092 [MIPS] Misc fixes for plat_irq_dispatch functions
o adds missing ST0_IM masks, which caused the logging of valid interrupts
   as spurious
 o stops pnx8550 to log every interrupt as spurious
 o adds cause register masks for ip22/ip32, which caused handling of masked
   interrupts
 o removes some superfluous parentheses in the SNI interrupt code

61dcc6f4d9 [MIPS] RTLX: Harden against compiler reordering and optimization.
RTLX communication is based on lock-free shared memory buffers.  It
happened to be working by luck so far but relies on the optimizer doing
certain optimizations but no reordering.

Fixed by inserting proper barriers in rtlx_read and rtlx_write, and careful
pointer dereferencing.

f6dfb4fd7d [PATCH] Add epoll compat_ code to fs/compat.c
IA64 and ARM-OABI are currently using their own version of epoll compat_
code.

An architecture needs epoll_event translation if alignof(u64) in 32 bit
mode is different from alignof(u64) in 64 bit mode.  If an architecture
needs epoll_event translation, it must define struct compat_epoll_event in
asm/compat.h and set CONFIG_HAVE_COMPAT_EPOLL_EVENT and use
compat_sys_epoll_ctl and compat_sys_epoll_wait.

All 64 bit architecture should use compat_sys_epoll_pwait.

[sfr: restructure and move to fs/compat.c, remove MIPS version
of compat_sys_epoll_pwait, use __put_user_unaligned]

84dd619e4d mv643xx_eth: Place explicit port number in mv643xx_eth_platform_data
We were using the platform_device.id field to identify which ethernet
port is used for mv643xx_eth device.  This is not generally correct.
It will be incorrect, for example, if a hardware platform uses a single
port but not the first port.  Here, we add an explicit port_number field
to struct mv643xx_eth_platform_data.

This makes the mv643xx_eth_platform_data structure required, but that
isn't an issue since all users currently provide it already.
