[ARM] 4016/1: prefetch macro is wrong wrt gcc's "delete-null-pointer-checks"
optimization
The gcc manual says:
|`-fdelete-null-pointer-checks'
| Use global dataflow analysis to identify and eliminate useless
| checks for null pointers. The compiler assumes that dereferencing
| a null pointer would have halted the program. If a pointer is
| checked after it has already been dereferenced, it cannot be null.
| Enabled at levels `-O2', `-O3', `-Os'.
Now the problem can be seen with this test case:
#include <linux/prefetch.h>
extern void bar(char *x);
void foo(char *x)
{
prefetch(x);
if (x)
bar(x);
}
Because the constraint to the inline asm used in the prefetch() macro is
a memory operand, gcc assumes that the asm code does dereference the
pointer and the delete-null-pointer-checks optimization kicks in.
Inspection of generated assembly for the above example shows that bar()
is indeed called unconditionally without any test on the value of x.
Of course in the prefetch case there is no real dereference and it
cannot be assumed that a null pointer would have been caught at that
point. This causes kernel oopses with constructs like
hlist_for_each_entry() where the list's 'next' content is prefetched
before the pointer is tested against NULL, and only when gcc feels like
applying this optimization which doesn't happen all the time with more
complex code.
It appears that the way to prevent delete-null-pointer-checks
optimization to occur in this case is to make prefetch() into a static
inline function instead of a macro. At least this is what is done on
x86_64 where a similar inline asm memory operand is used (I presume they
would have seen the same problem if it didn't work) and resulting code
for the above example confirms that.
An alternative would consist of replacing the memory operand by a
register operand containing the pointer, and use the addressing mode
explicitly in the asm template. But that would be less optimal than an
offsettable memory reference.

[PATCH] Fix COW D-cache aliasing on fork
Problem:
1. There is a process containing two thread (T1 and T2). The
thread T1 calls fork(). Then dup_mmap() function called on T1 context.
static inline int dup_mmap(struct mm_struct *mm, struct mm_struct *oldmm)
...
flush_cache_mm(current->mm);
... /* A */
(write-protect all Copy-On-Write pages)
... /* B */
flush_tlb_mm(current->mm);
...
2. When preemption happens between A and B (or on SMP kernel), the
thread T2 can run and modify data on COW pages without page fault
(modified data will stay in cache).
3. Some time after fork() completed, the thread T2 may cause a page
fault by write-protect on a COW page.
4. Then data of the COW page will be copied to newly allocated
physical page (copy_cow_page()). It reads data via kernel mapping.
The kernel mapping can have different 'color' with user space
mapping of the thread T2 (dcache aliasing). Therefore
copy_cow_page() will copy stale data. Then the modified data in
cache will be lost.
In order to allow architecture code to deal with this problem allow
architecture code to override copy_user_highpage() by defining
__HAVE_ARCH_COPY_USER_HIGHPAGE in <asm/page.h>.

[PATCH] Add support for Korenix 16C950-based PCI cards
This adds initial support to 8250-pci for the Korenix Jetcard PCI serial
cards. The JC12xx cards are standard RS232-based serial cards utilising
the Oxford 16C950 device.
The JC14xx are RS422/RS485-based cards, but in order for these to be
supported natively, we will need additional tweaks to the 8250 layers so
we can specify some values for the 950's registers. Hence, these two
entries are commented out.

[PATCH] ide: HPT3xxN clocking fixes
Fix serious problems with the HPT372N clock turnaround code:
- the wrong ports were written to when called for the secondary channel;
- it didn't serialize access to the channels;
- turnaround shou;dn't be done on 66 MHz PCI;
- caching the clock mode per-channel caused it to get out of sync with the
actual register value.
Additionally, avoid calibrating PLL twice (for each channel) as the second try
results in a wrong PCI frequency and thus in the wrong timings.
Make the driver deal with HPT302N and HPT371N correctly -- the clocking and
(seemingly) a need for clock tunaround is the same as for HPT372N. HPT371/N
chips have only one, secondary channel, so avoid touching their "pure virtual"
primary channel, and disable it if the BIOS haven't done this already.
Also, while at it, disable UltraATA/133 for HPT372 by default -- 50 MHz DPLL
clock don't allow for this speed anyway. And remove the traces of the former
bad patch that wasn't even applicable to this version of driver.
Has been tested on HPT370/371N, unfortunately I don't have an instant access
to the other chips...

[PATCH] Optimize calc_load()
calc_load() is called by timer interrupt to update avenrun[]. It currently
calls nr_active() at each timer tick (HZ per second), while the update of
avenrun[] is done only once every 5 seconds. (LOAD_FREQ=5 Hz)
nr_active() is quite expensive on SMP machines, since it has to sum up
nr_running and nr_uninterruptible of all online CPUS, bringing foreign
dirty cache lines.
This patch is an optimization of calc_load() so that nr_active() is called
only if we need it.
The use of unlikely() is welcome since the condition is true only once every
5*HZ time.

"drop" the request and save enough information so that we can revisit it

Certain failures during the deferral process can cause us to really drop the

This is often less than ideal, and is unacceptable in the NFSv4 case--rfc 3530
forbids the server from dropping a request without also closing the

[PATCH] ncpfs: ensure we free wdog_pid on parse_option or fill_inode failure
This took a little refactoring but now errors are handled cleanly. When
this code used pid_t values this wasn't necessary because you can't
leak a pid_t.
Thanks to Peter Vandrovec for spotting this.

This patch converts the tracking of the user space watchdog process from using

[PATCH] n_r3964: Use struct pid to track user space clients
Currently this driver tracks user space clients it should send signals to. In
the presenct of file descriptor passing this is appears susceptible to
confusion from pid wrap around issues.
Replacing this with a struct pid prevents us from getting confused, and
prepares for a pid namespace implementation.

Fix a glitch in the procfs dumping of whether the alarm IRQ is enabled: use
the traditional name (from drivers/char/rtc.c and many other places) of

originated that reporting API).
Also, update a few of the RTC drivers to stop providing that duplicate status,
and/or to expose it properly when reporting the alarm state. We really don't

[PATCH] Use activate_mm() in fs/aio.c:use_mm()
activate_mm() is not the right thing to be using in use_mm(). It should be
switch_mm().
On normal x86, they're synonymous, but for the Xen patches I'm adding a
hook which assumes that activate_mm is only used the first time a new mm
is used after creation (I have another hook for dealing with dup_mm). I
think this use of activate_mm() is the only place where it could be used
a second time on an mm.
>From a quick look at the other architectures I think this is OK (most
simply implement one in terms of the other), but some are doing some
subtly different stuff between the two.
