+ help
+ This option allows for the kernel to be compiled using the latest

+
+ Since there are major incompatibilities between the legacy ABI and
+ EABI, especially with regard to structure member alignment, this

+ This option preserves the old syscall interface along with the

+ intercept syscalls that have structure arguments which layout
+ in memory differs between the legacy ABI and the new ARM EABI
+ (only for non "thumb" binaries). This option adds a tiny
+ overhead to all syscalls and produces a slightly larger kernel.
+ If you know you'll be using only pure EABI user space then you

+ * The legacy ABI and the new ARM EABI have different rules making some

+ * Most notably, Eabi says 64-bit members should be 64-bit aligned instead of

+ * member it contains instead of the invariant 32-bit.
+ *
+ * The following syscalls are affected:
+ *
+ * sys_stat64:
+ * sys_lstat64:
+ * sys_fstat64:
+ *
+ * struct stat64 has different sizes and some members are shifted
+ * Compatibility wrappers are needed for them and provided below.
+ *
+ * sys_fcntl64:
+ *
+ * struct flock64 has different sizes and some members are shifted
+ * A compatibility wrapper is needed and provided below.
+ *
+ * sys_statfs64:
+ * sys_fstatfs64:
+ *
+ * struct statfs64 has extra padding with EABI growing its size from
+ * 84 to 88. This struct is now __attribute__((packed,aligned(4)))
+ * with a small assembly wrapper to force the sz argument to 84 if it is 88
+ * to avoid copying the extra padding over user space unexpecting it.
+ *
+ * sys_newuname:
+ *
+ * struct new_utsname has no padding with EABI. No problem there.
+ *
+ * sys_epoll_ctl:
+ * sys_epoll_wait:
+ *
+ * struct epoll_event has its second member shifted also affecting the
+ * structure size. Compatibility wrappers are needed and provided below.
+ *
+ * sys_ipc:
+ * sys_semop:
+ * sys_semtimedop:
+ *
+ * struct sembuf loses its padding with EABI. Since arrays of them are

+ * Our solution:
+ * (1) Allocate resources for all buses behind PCI-to-PCI bridges.
+ * This gives us fixed barriers on where we can allocate.
+ * (2) Allocate resources for all enabled devices. If there is
+ * a collision, just mark the resource as unallocated. Also

+ * resources were assigned correctly, everything goes well,

+ ---help---
+ This is the driver for the built-in watchdog timer on the EPX-C3
+ Single-board computer made by Winsystems, Inc.
+
+ *Note*: This hardware watchdog is not probeable and thus there
+ is no way to know if writing to its IO address will corrupt
+ your system or have any real effect. The only way to be sure
+ that this driver does what you want is to make sure you
+ are runnning it on an EPX-C3 from Winsystems with the watchdog
+ timer at IO address 0x1ee and 0x1ef. It will write to both those
+ IO ports. Basically, the assumption is made that if you compile
+ this driver into your kernel and/or load it as a module, that you
+ know what you are doing and that you are in fact running on an
+ EPX-C3 board!
+
+ To compile this driver as a module, choose M here: the
+ module will be called sbc_epx_c3.
