Hi all,
FYI, I just came across the following warnings when compiling 2.6.27
(release) using gcc 4.3.2 (Debian 4.3.2-1) on Debian Lenny (i386):
----------
drivers/acpi/tables/tbfadt.c: In function ‘acpi_tb_create_local_fadt’:
include/asm/string_32.h:75: warning: array subscript is above array bounds
drivers/usb/core/hcd.c: In function ‘usb_hcd_poll_rh_status’:
include/asm/string_32.h:75: warning: array subscript is above array bounds
fs/xfs/xfs_mount.c: In function ‘xfs_mod_sb’:
fs/xfs/xfs_mount.c:1456: warning: array subscript is above array bounds
----------
Cheers,
Oliver

Does this refer to the call to memcpy() in usb_hcd_poll_rh_status()?
Line 75 in string_32.h is part of the __constant_memcpy() function.
That function should not be involved here because the length argument
isn't a compile-time constant.
This has to be either a compiler bug or else a bug in the
implementation of memcpy.
