Well, first of all, I don't want to change so many files either.
What I do:
Adding a new parameter "struct bin_attribute *" in the
.read/.write methods for the sysfs binary attributes.In fact, only the four lines change in fs/sysfs/bin.c and
include/linux/sysfs.h do the real work.
But I have to update all the files that use binary attributes
to make them compatible with the new .read and .write methods.
I'm not sure if I missed any. :(Why I do this:
For a sysfs attribute, we can get a pointer pointing to the
struct attribute in the .show/.store method,
while we can't do this for the binary attributes.
I don't know why this is different, but this does make it not
so handy to use the binary attributes as the regular ones.
So I think this patch is reasonable. :)Who benefits from it:
The patch that exposes ACPI tables in sysfs
requires such an improvement.
All the table binary attributes share the same .read method.
Parameter "struct bin_attribute *" is used to get
the table signature and instance number which are used to
distinguish different ACPI table binary attributes.Without this parameter, we need to offer different .read methods
for different ACPI table binary attributes.
This is impossible as there are various ACPI tables on different
platforms, and we don't know what they are until they are loaded.Signed-off-by: Zhang Rui

sysfs is now completely out of driver/module lifetime game. After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners. Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.This patch kills now unnecessary attribute->owner. Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.For more info regarding lifetime rule cleanup, please read the
following message.http://article.gmane.org/gmane.linux.kernel/510293

Intel Macs (and possibly other machines) provide a PNP entry for the RTC,
but provide no IRQ. As a result the rtc-cmos driver doesn't allow wakeup
alarms. If the RTC is located at the legacy ioport range, assume that it's
on IRQ 8 unless the tables say otherwise.Signed-off-by: Matthew Garrett

This fixes a common glitch in how RTC drivers handle two "set alarm" modes,
by getting rid of the surprising/hidden one that was rarely implemented
correctly (and which could expose nonportable hardware-specific behavior).The glitch comes from the /dev/rtcX logic implementing the legacy
RTC_ALM_SET (limited to 24 hours, needing RTC_AIE_ON) ioctl on top of the
RTC driver call providing access to the newer RTC_WKALM_SET (without those
limitations) by initializing the day/month/year fields to be invalid ...
that second mode.Now, since few RTC drivers check those fields, and most hardware misbehaves
when faced with invalid date fields, many RTC drivers will set bogus alarm
times on those RTC_ALM_SET code paths. (Several in-tree drivers have that
issue, and I also noticed it with code reviews on several new RTC drivers.)This patch ensures that RTC drivers never see such invalid alarm fields, by
moving some logic out of rtc-omap into the RTC_ALM_SET code and adding an
explicit check (which will prevent the issue on other code paths).Signed-off-by: David Brownell

David says "884b4aaaa242a2db8c8252796f0118164a680ab5 should be reverted. It
added an rtc_merge_alarm() call to the 2.6.20 kernel, which hasn't yet been
used by any in-tree driver; this patch obviates the need for that call, and
uses a more robust approach."Cc: Scott Wood

I finally got around to testing the updated wakeup event hooks for rtc-cmos,
and they follow in two patches:- Interface update ... when a simple enable_irq_wake() doesn't suffice,
the platform data can hold suspend/resume callback hooks.- ACPI implementation ... provides callback hooks to do ACPI magic, and
eliminate the legacy /proc/acpi/alarm file.The interface update could go into 2.6.21, but that's not essential; they
will be NOPs on most PCs, without the ACPI stuff.I suspect the ACPI folk may have opinions about how to merge that second
patch, and how to obsolete that legacy procfs file. I'd like to see that
merge into 2.6.22 if possible...As for how to kick it in ... two ways:
- The appended "rtcwake" program; updated since the last time it was
posted, it deals much better with timezones and DST.- Write the /sys/class/rtc/.../wakealarm file, then go to sleep.
For some reason RTC wake from "swsusp" stopped working on a system where
it previously worked; the alarm setting appears to get clobbered. But
on the bright side, RTC wake from "standby" worked on a system that had
never been able to resume from that state before ... IDEACPI is my guess
as to why it finally started to work. It's the old "two steps forward,
one step back" dance, I guess.- Dave

* This uses cross-platform Linux interfaces to enter a system sleep state,

* RTC uses a local timezone instead (maybe you dual-boot MS-Windows).

}This patch:
Make rtc-cmos do the relevant magic so this RTC can wake the system from a
sleep state. That magic comes in two basic flavors:- Straightforward: enable_irq_wake(), the way it'd work on most SOC chips;
or generally with system sleep states which don't disable core IRQ logic.- Roundabout, using non-IRQ platform hooks. This is needed with ACPI and
one almost-clone chip which uses a special wakeup-only alarm. (That's
the RTC used on Footbridge boards, FWIW, which don't do PM in Linux.)A separate patch implements those hooks for ACPI platforms, so that rtc_cmos
can issue system wakeup events (and its sysfs "wakealarm" attribute works on
at least some systems).Signed-off-by: David Brownell

RTC class suspend/resume support, re-initializing the system clock on resume
from the clock used to initialize it at boot time.- The reinit-on-resume is hooked to the existing RTC_HCTOSYS config
option, on the grounds that a clock good enough for init must also
be good enough for re-init.- Inlining a version of the code used by ARM, to save and restore the
delta between a selected RTC and the current system wall-clock time.- Removes calls to that ARM code from AT91, OMAP1, and S3C RTCs. This
means that systems using those RTCs across suspend/resume will likely
want to change their kernel configs to enable RTC_HCTOSYS.If HCTOSYS isn't using a second RTC (with battery?), this changes the
system's initial date from Jan 1970 to the epoch this hardware uses:
1998 for AT91, 2000 for OMAP1 (assuming no split power mode), etc.This goes on top of the patch series removing "struct class_device" usage
from the RTC framework. That's all needed for class suspend()/resume().Signed-off-by: David Brownell

This simplifies the RTC procfs support by removing the class_interface that
hooks it into the rtc core. If it's configured, then sysfs support is now
part of the RTC core, and is never a separate module.It also removes the class_interface hook, now that its last remaining user is
gone. (That API is usable only with a "struct class_device".)It's another step towards being able to remove "struct class_device".

Lockdep reported cmos_suspend() and cmos_resume() calling rtc_update_irq()
with IRQs enabled; not allowed.Also fix problems seen on some hardware, whereby false alarm IRQs could be
reported (primarily to userspace); and update two comments to match changes
in ACPI. Those make up most of this patch, by volume.Signed-off-by: David Brownell

Replace the I2C bus address, as per drivers/acorn/char/pcf8583.c.
Also, since this driver also contains Acorn RiscPC specific code
for obtaining the current year from the SRAM (and updating the
platform specific checksum when writing new data back) this is
NOT a platform independent driver.Document it as such, and update the dependencies to reflect this
fact.Signed-off-by: Russell King

Both BCD_TO_BIN(x) and BIN_TO_BCD(x) have an unexpected side-effect -
not only do they return the value as expected, they _modify_ their
argument in the process.Let's play it safe and avoid these macros.
