And then drop a few hunks which conflicted with outstanding work.

The undocumented register BIOS uses for saving f_CNT seems to only be mapped to I/O space while all the other HPT3xx regs are dual-mapped. Looks like another HighPoint's dirty trick. With this patch, the deadly kernel oops on the cards having the modern HighPoint BIOSes is now at last gone! Signed-off-by:

Fix the broken hotswap code: on HPT37x it caused RESET- to glitch when tristating the bus (the MISC control 3/6 and soft control 2 need to be written to in the certain order), and for HPT36x the obsolete HDIO_TRISTATE_HWIF ioctl() handler was called instead which treated the state argument wrong. Also, get rid of the soft control reg. 1 wtite to enable IDE interrupt -- this is done in init_hpt37x() already... Have been tested on HPT370 and 371N. Signed-off-by:

Save some space on the timing tables by introducing the separate transfer mode table in which the mode lookup is done to get the index into the timing table itself. Get rid of the rest of the obsolete/duplicate tables and use one set of tables for the whole HPT37x chip family like the HighPoint open-source drivers do. Documnent the different timing register layout for the HPT36x chip family (this is my guesswork based on the timing values). Have been tested and works fine on HPT370/302/371N. Signed-off-by:

Fix/remove bad/unused timing tables: HPT370/A 66 MHz tables weren't really needed (the chips are not UltraATA/133 capable and shouldn't support 66 MHz PCI) and had many modes over- and underclocked, HPT372 33 MHz table was in fact for 66 MHz and 50 MHz table missed UltraDMA mode 6, HPT374 33 MHz table was really for 50 MHz... (Actually, HPT370/A 33 MHz tables also have issues. e.g. HPT370 has PIO modes 0/1 overlocked.) There's also no need in the separate HPT374 tables because HPT372 timings should be the same (and those tables has UltraDMA mode 6 which HPT374 supports depending on HPT374_ALLOW_ATA133_6 #define)...

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...

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. Signed-off-by:

The nfsservctl system call isn't used but recent nfs-utils releases for exporting filesystems, and consequently the code that is uses - exp_export - has suffered some bitrot. Particular: - some newly added fields in 'struct svc_export' are being initialised properly. - the return value is now always -ENOMEM ... This patch fixes both these problems.

I'm not too fond of these big if conditions. Replace them by checks of a flag in the operation descriptor. To my eye this makes the code a bit more self-documenting, and makes the complicated part of the code (proc_compound) a little more compact. Signed-off-by:

Pass the saved and current filehandles together into all the nfsd4 compound operations. I want a unified interface to these operations so we can just call them by pointer and throw out the huge switch statement. Also I'll eventually want a structure like this--that holds the state used during compound processing--for deferral. Signed-off-by:

There's no point deferring something just to immediately fail the deferral, especially now that we can do something more useful in the failure case by returning an error. Signed-off-by:

J.Bruce Fields authored
To avoid tying up server threads when nfsd makes an upcall (to mountd, to get export options, to idmapd, for nfsv4 name<->id mapping, etc.), we temporarily "drop" the request and save enough information so that we can revisit it later. Certain failures during the deferral process can cause us to really drop the request and never revisit it. 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 connection. As a first step, we modify the deferral code to return -ETIMEDOUT (which is translated to nfserr_jukebox in the v3 and v4 cases, and remains a drop in the v2 case). Signed-off-by:
-
J.Bruce Fields authored
This patch on its own causes no change in behavior, since nfsd_cross_mnt() only returns -EAGAIN; but in the future I'd like it to also be able to return -ETIMEDOUT, so we may as well handle any possible error here. Signed-off-by:

Note there's no need for special handling of -EAGAIN here; nfserrno() does what we want already. So this is a pure cleanup with no change in functionality. Signed-off-by:

Since exp_parent can fail by returning an error (-EAGAIN) in addition to by returning NULL, we should check for that case in exp_rootfh. (TODO: we should check that userland handles these errors too.) Signed-off-by:

A comment here incorrectly states that "slack_space" is measured in words, not bytes. Remove the comment, and adjust a variable name and a few comments to clarify the situation. This is pure cleanup; there should be no change in functionality. Signed-off-by:

The BLK_DEV_SWIM_IOP driver has: - already been marked as BROKEN in 2.6.0 three years ago and - is still marked as BROKEN. Drivers that had been marked as BROKEN for such a long time seem to be unlikely to be revived in the forseeable future. But if anyone wants to ever revive this driver, the code is still present in the older kernel releases. Signed-off-by:

Eric W. Biederman authored
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. Signed-off-by:

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 "alarm_IRQ", not "alrm_wakeup" (which didn't even match the efirtc code, which 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 want every RTC driver doing their own thing here... Signed-off-by:
