They were added by Torben to workaround ServerWorks driver problems
(fixed by previous patch), but depending on BIOS can be dangerous on
other chipsets and it is always better to fix specific driver.
If PIO mode should be auto-tuned xferspeed argument for svwks_tune_chipset()
is equal to 255 (0xFF). It is then passed to ide_rate_filter() which matches
desired mode with chipset capabilities. Since 255 is greater than any of the
values used for transfer modes, ide_rate_filter() will always return the
highest mode supported by both device/chipset (which sometimes should not be
used ie. when host is a simplex one) and the wrong mode will be set.
Thanks to Torben Mathiasen and Tomas Szepe for testing it.

[PATCH] ia64: MCA min_state area must be uncacheable
Software Developer's Manual page 2:270, section 11.3.2.3
says that the processor min-state save area must be in an
uncacheable region ... but current MCA recovery code
allocates the min-state area "ia64_mca_min_state_save_info"
in regular kernel data/bss.
This patch re-uses the same min-state area that the PAL/SAL
used to report the error to Linux ... which mostly requires
deleting code and declarations (some of which were wrong,
MIN_STATE_AREA_SIZE ought to have been 58). The real "work"
is copying the pointer to the min-state area from the
sal_to_os handoff structure into the os_to_sal structure.

The driver seems to be aware of the problem and has a workaround for

reason is that the model of my drive is "IOMEGA ZIP 100 ATAPI Floppy"

[PATCH] drivers/block/initrd.c removal
From: viro@parcelfarce.linux.theplanet.co.uk
* drivers/block/initrd.c gone
* chunk of memory where the current tree would look for intird image is
checked for being a valid initramfs image first; then, it is either
unpacked (in addition to normal built-in image) or, if it wasn't a valid
image, copied into a regular file on rootfs called /dev/initrd. Then
memory is freed.
Result:
a) we can put initramfs image in place of initrd one and kernel will DTRT.
b) initrd images still work as usual; code that shoves the thing to
ramdisk, etc. doesn't care whether it reads from a block device or
regular file.
c) initrd.c is gone, so is fake block device and a lot of irregularities
with it.
It has been in -mm for almost two weeks with no reported problems.

[PATCH] update to microcode update driver
This contains the following changes:
a) changes from Intel to support the new microcode data format
(backward compatible of course)
b) changes from me to remove the no longer needed features of the driver,
namely we don't need to keep a copy of applied microcode in kernel
memory.
This feature was hardly useful in the days of regular devfs
/dev/cpu/microcode file and now it is completely useless so I removed
it (after taking into account all the feedback on linux-kernel I
received since the announcement of the intention to do this)
These are rather critical because otherwise we can't really say Linux
fully supports the very latest Intel cpus (which require microcode in
the new format).

[PATCH] ia64: fix serial port naming
Now that the serial driver fully supports discovery via ACPI,
we can get rid of all the legacy junk in asm-ia64/serial.h.
This keeps the serial driver from blindly probing I/O port
space.
This also fixes a long-standing serial device naming issue:
ttyS0-ttyS3 were always reserved for the compiled-in
COM ports, even if they weren't present in the box.
Any additional PCI or ACPI ports appeared starting at
ttyS4 (except for the special case of things described
in the HCDP). Now we'll just name ttyS devices in the
order they're discovered, without any holes for non-existent
devices.
This is a little bit ugly for serial console because the HCDP
is currently the only way we learn about serial ports before
the actual ACPI discovery. All HP firmware implements HCDP,
but Intel firmware does not. So in the absence of an HCDP,
we have to probe for legacy COM ports. Otherwise, the serial
console wouldn't work until the serial driver discovers the
port via ACPI.
