      [PATCH] getting rid of all casts of k[cmz]alloc() calls · 5cbded58
      由 Robert P. J. Day 提交于 
      Run this:

	#!/bin/sh
	for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
	  echo "De-casting $f..."
	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
	done

And then go through and reinstate those cases where code is casting pointers
to non-pointers.

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

      [PATCH] HPT37x: read f_CNT saved by BIOS from port · f13c1526
      由 Sergei Shtylyov 提交于 
      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!

      Use the f_CNT value saved by the HighPoint BIOS if available as reading it
directly would give us a wrong PCI frequency after DPLL has already been

      [PATCH] ide: fix HPT3xx hotswap support · 33b18a60
      由 Sergei Shtylyov 提交于 
      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.

      [PATCH] ide: optimize HPT37x timing tables · 471a0bda
      由 Sergei Shtylyov 提交于 
      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.

      [PATCH] ide: fix HPT37x timing tables · 9448732f
      由 Sergei Shtylyov 提交于 
      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)...

      [PATCH] ide: HPT3xxN clocking fixes · 836c0063
      由 Sergei Shtylyov 提交于 
      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] remove blk_queue_activity_fn · 2b02a179
      由 Boaz Harrosh 提交于 
      While working on bidi support at struct request level
I have found that blk_queue_activity_fn is actually never used.
The only user is in ide-probe.c with this code:

	/* enable led activity for disk drives only */
	if (drive->media == ide_disk && hwif->led_act)
		blk_queue_activity_fn(q, hwif->led_act, drive);

And led_act is never initialized anywhere.
(Looking back at older kernels it was used in the PPC arch, but was removed around 2.6.18)
Unless it is all for future use off course.
(this patch is against linux-2.6-block.git as off 2006/12/4)

        rmmod/3080 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:
   (proc_subdir_lock){--..}, at: [<c04a33b0>] remove_proc_entry+0x40/0x191

  and this task is already holding:
   (ide_lock){++..}, at: [<c05651a2>] ide_unregister_subdriver+0x39/0xc8
  which would create a new lock dependency:
   (ide_lock){++..} -> (proc_subdir_lock){--..}

  but this new dependency connects a hard-irq-safe lock:
   (ide_lock){++..}
  ... which became hard-irq-safe at:
    [<c043c458>] lock_acquire+0x4b/0x6b

    [<c044ebf2>] __do_IRQ+0x94/0xef

  to a hard-irq-unsafe lock:

  ... which became hard-irq-unsafe at:
  ...  [<c043c458>] lock_acquire+0x4b/0x6b

    [<c07c1844>] proc_root_init+0x4c/0xe9
    [<c07ad703>] start_kernel+0x294/0x3b3

Move ide_remove_proc_entries() out from under ide_lock; there is nothing
that indicates that this is needed.

In specific, the call to ide_add_proc_entries() is unprotected, and there
is nothing else in the file using the respective ->proc fields. Also the
lock order around destroy_proc_ide_interface() suggests this.

Alan sayeth:

  proc_ide_write_settings walks the setting list under ide_setting_sem, read
  ditto.  remove_proc_entry is doing proc side housekeeping.

  Looks fine to me, although that old code is such a mess anything could be
  going on.
