I noticed that 2.6.24.2 calculates bprm->argv_len at do_execve(). But it
doesn't update bprm->argv_len after "remove_arg_zero() +
copy_strings_kernel()" at load_script() etc.
audit_bprm() is called from search_binary_handler() and
search_binary_handler() is called from load_script() etc. Thus, I think the
condition check
if (bprm->argv_len > (audit_argv_kb << 10))
return -E2BIG;
in audit_bprm() might return wrong result when strlen(removed_arg) !=
strlen(spliced_args). Why not update bprm->argv_len at load_script() etc. ?
By the way, 2.6.25-rc3 seems to not doing the condition check. Is the field
bprm->argv_len no longer needed?

The kernel is sent to tainted within the warn_on_slowpath() function, and
whenever a warning occurs the new taint flag 'W' is set. This is useful to
know if a warning occurred before a BUG by preserving the warning as a flag
in the taint state.
This does not work on architectures where WARN_ON has its own definition.
These archs are:
1. s390
2. superh
3. avr32
4. parisc
The maintainers of these architectures have been added in the Cc: list
in this email to alert them to the situation.
The documentation in oops-tracing.txt has been updated to include the
new flag.

BITS_PER_LONG is a signed value (32 or 64)
DIV_ROUND_UP(nr, BITS_PER_LONG) performs signed arithmetic if "nr" is signed too.
Converting BITS_TO_LONGS(nr) to DIV_ROUND_UP(nr, BITS_PER_BYTE *
sizeof(long)) makes sure compiler can perform a right shift, even if "nr"
is a signed value, instead of an expensive integer divide.
Applying this patch saves 141 bytes on x86 when CONFIG_CC_OPTIMIZE_FOR_SIZE=y

The definition and use of __GFP_REPEAT, __GFP_NOFAIL and __GFP_NORETRY in the
core VM have somewhat differing comments as to their actual semantics.
Annoyingly, the flags definition has inline and header comments, which might
be interpreted as not being equivalent. Just add references to the header
comments in the inline ones so they don't go out of sync in the future. In
their use in __alloc_pages() clarify that the current implementation treats
low-order allocations and __GFP_REPEAT allocations as distinct cases.
To clarify, the flags' semantics are:
__GFP_NORETRY means try no harder than one run through __alloc_pages
__GFP_REPEAT means __GFP_NOFAIL
__GFP_NOFAIL means repeat forever
order <= PAGE_ALLOC_COSTLY_ORDER means __GFP_NOFAIL

Since both the IDE interface and SMC 91C111 Ethernet chip are on-board
devices, not SOC devices, move the platform device registration form the
common to the board specific code.
While at it, remove semicolon (which didn't break compilation only by
chance) from the AU1XXX_ATA_DDMA_REQ macro and do some renaming:
- change 'au1200_ide0_' variable name prefix to the mere 'ide_';
- change 'smc91x_' variable name prefix to 'smc91c111_' since that's the
name of the chip used on the boards;
- drop 'AU1XXX_' prefix from the names of macros describing IDE and Ethernet
on-board devices;
- change 'SMC91111_' to 'SMC91C111_', change 'IRQ' to 'INT' in the names of
the macros describing the Ethernet chip for consistency with the IDE
macros;
- change 'ATA_' to 'IDE_' and 'OFFSET' to 'SHIFT' (since this value is
indeed a shift count) in the names of the macros describing the IDE
interface.
