These have been broken (returning "int") since the dawn of

until commit
424acaaeb3a3932d64a9b4bd59df6cf72c22d8f3
rwsem: wake queued readers when writer blocks on active read lock
made this change:
- (rwsem_atomic_update(0, sem) & RWSEM_ACTIVE_MASK))
- /* Someone grabbed the sem already */
+ rwsem_atomic_update(0, sem) < RWSEM_WAITING_BIAS)
+ /* Someone grabbed the sem for write already */
RWSEM_ACTIVE_MASK is 0xffffffffL, so the old code only looked
at the low order 32-bits. The new code needs to see all 64 bits.

This driver supports both iLO2 and iLO3, but our user-visible strings
currently only reference iLO2. Let's just call it "iLO2+" to avoid having
to update strings for each iLO generation. This driver doesn't support
iLO ASICs prior to iLO2, but that is sufficiently explained in Kconfig.

Until now, the tile architecture ABI for syscall return has just been
that r0 holds the return value, and an error is only signalled like it is
for kernel code, with a negative small number.
However, this means that in multiple places in userspace we end up writing
the same three-cycle idiom that tests for a small negative number for
error. It seems cleaner to instead move that code into the kernel, and
set r1 to hold zero on success or errno on failure; previously, r1 was
just zeroed on return from the kernel (to avoid leaking kernel state).
This way a single conditional branch after the syscall is sufficient
to test for the failure case. The number of cycles taken is the same,
but the error-checking code is in just one place, so total code size is
smaller, and random userspace syscall code is easier to understand.

When userspace code writes non-new-line-terminated string to trace_marker
file, write handler appends new-line and returns number of bytes written
to trace buffer, so
write(fd, "abc", 3) will return 4
That's unexpected and unfortunately it confuses glibc's fprintf function.
Example:
int main() {
fprintf(stderr, "abc");
return 0;
}
$ gcc test.c -o test
$ echo mmiotrace > /sys/kernel/debug/tracing/current_tracer
$ ./test 2>/sys/kernel/debug/tracing/trace_marker
results in infinite loop:
write(fd, "abc", 3) = 4
write(fd, "", 1) = 0
write(fd, "", 1) = 0
write(fd, "", 1) = 0
write(fd, "", 1) = 0
write(fd, "", 1) = 0
write(fd, "", 1) = 0
write(fd, "", 1) = 0
(...)
...and kernel trace buffer full of empty markers.
Fix it by sanitizing write return value.

Early 4.3 versions of gcc apparently aggressively optimize the raw
time accumulation loop, replacing it with a divide.
On 32bit systems, this causes the following link errors:
undefined reference to `__umoddi3'
undefined reference to `__udivdi3'
The gcc issue has been fixed in 4.4 and greater.
This patch replaces the accumulation loop with a do_div, as suggested
by Linus.

Atheros PCIe wireless cards handled by ath5k do require L0s disabled.
For distributions shipping with CONFIG_PCIEASPM (this will be enabled
by default in the future in 2.6.36) this will also mean both L1 and L0s
will be disabled when a pre 1.1 PCIe device is detected. We do know L1
works correctly even for all ath5k pre 1.1 PCIe devices though but cannot
currently undue the effect of a blacklist, for details you can read
pcie_aspm_sanity_check() and see how it adjusts the device link
capability.
It may be possible in the future to implement some PCI API to allow
drivers to override blacklists for pre 1.1 PCIe but for now it is
best to accept that both L0s and L1 will be disabled completely for
distributions shipping with CONFIG_PCIEASPM rather than having this
issue present. Motivation for adding this new API will be to help
with power consumption for some of these devices.
Example of issues you'd see:
- On the Acer Aspire One (AOA150, Atheros Communications Inc. AR5001
Wireless Network Adapter [168c:001c] (rev 01)) doesn't work well
with ASPM enabled, the card will eventually stall on heavy traffic
with often 'unsupported jumbo' warnings appearing. Disabling
ASPM L0s in ath5k fixes these problems.
- On the same card you would see a storm of RXORN interrupts
even though medium is idle.
Credit for root causing and fixing the bug goes to Jussi Kivilinna.

Some APs advertise that they may be HT40 capable in the capabilites
but the current operating channel configuration may be only HT20.
This causes disconnection as ath9k_htc sets WLAN_RC_40_FLAG despite
the AP operating in HT20 mode.
Hence set this flag only if the current channel configuration
is HT40 enabled.
