[PATCH] mempool: add page allocator

This will be used by the next patch in the series to replace duplicate
mempool-backed page allocators in 2 places in the kernel.  It is also likely
that there will be more users in the future.

Andrew Morton [Sun, 26 Mar 2006 09:37:32 +0000]
[PATCH] remove fixup_cpu_present_map()

Since the addition of boot_cpu_init(), fixup_cpu_present_map() has been a
no-op.  That's because fixup_cpu_present_map() won't touch cpu_present_map if
it has any bits set, and boot_cpu_init() sets a bit.

So remove fixup_cpu_present_map().

A consequence of this (actually of the boot_cpu_init() change) is that the
architecture _must_ populate cpu_present_map itself (probably in
smp_prepare_cpus()).  fixup_cpu_present_map() won't do it any more.

If the architecture doesn't do this, it'll only bring up a single CPU.

The other side effect (though less serious) is that smp_prepare_boot_cpu() no
longer needs to mark the boot cpu in the online and present maps -
boot_cpu_init() does that for everyone (to make early printks work).

Andrew Morton [Sun, 26 Mar 2006 09:37:31 +0000]
[PATCH] tlclk: fix handling of device major

tlclk calls register_chrdev() and permits register_chrdev() to allocate the
major, but it promptly forgets what that major was.  So if there's no hardware
present you still get "telco_clock" appearing in /proc/devices and, I assume,
an oops reading /proc/devices if tlclk was a module.

Fix.

Mark, I'd suggest that that we not call register_chrdev() until _after_ we've
established that the hardware is present.

[PATCH] ipmi: add full sysfs support

Add full driver model support for the IPMI driver.  It links in the proper
bus and device support.

It adds an "ipmi" driver interface that has each BMC discovered by the
driver (as a device).  These BMCs appear in the devices/platform directory.
 If there are multiple interfaces to the same BMC, the driver should
discover this and will only have one BMC entry.  The BMC entry will have
pointers to each interface device that connects to it.

The device information (statistics and config information) has not yet been
ported over to the driver model from proc, that will come later.

This work was based on work by Yani Ioannou.  I basically rewrote it using
that code as a guide, but he still deserves credit :).

14 years ago[PATCH] EFI: keep physical table addresses in efi structure
Bjorn Helgaas [Sun, 26 Mar 2006 09:37:08 +0000]
[PATCH] EFI: keep physical table addresses in efi structure

Almost all users of the table addresses from the EFI system table want
physical addresses.  So rather than doing the pa->va->pa conversion, just keep
physical addresses in struct efi.

This fixes a DMI bug: the efi structure contained the physical SMBIOS address
on x86 but the virtual address on ia64, so dmi_scan_machine() used ioremap()
on a virtual address on ia64.

This is essentially the same as an earlier patch by Matt Tolentino:
http://marc.theaimsgroup.com/?l=linux-kernel&m=112130292316281&w=2
except that this changes all table addresses, not just ACPI addresses.

Matt's original patch was backed out because it caused MCAs on HP sx1000
systems.  That problem is resolved by the ioremap() attribute checking added
for ia64.

[PATCH] ia64: use i386 dmi_scan.c

Enable DMI table parsing on ia64.

Andi Kleen has a patch in his x86_64 tree which enables the use of i386
dmi_scan.c on x86_64.  dmi_scan.c functions are being used by the
drivers/char/ipmi/ipmi_si_intf.c driver for autodetecting the ports or
memory spaces where the IPMI controllers may be found.

This patch adds equivalent changes for ia64 as to what is in the x86_64
tree.  In addition, I reworked the DMI detection, such that on EFI-capable
systems, it uses the efi.smbios pointer to find the table, rather than
brute-force searching from 0xF0000.  On non-EFI systems, it continues the
brute-force search.

My test system, an Intel S870BN4 'Tiger4', aka Dell PowerEdge 7250, with
latest BIOS, does not list the IPMI controller in the ACPI namespace, nor
does it have an ACPI SPMI table.  Also note, currently shipping Dell x8xx
EM64T servers don't have these either, so DMI is the only method for
obtaining the address of the IPMI controller.

14 years ago[PATCH] i386: export: memory more than 4G through /proc/iomem
Vivek Goyal [Sun, 26 Mar 2006 09:37:02 +0000]
[PATCH] i386: export: memory more than 4G through /proc/iomem

Currently /proc/iomem exports physical memory also apart from io device
memory.  But on i386, it truncates any memory more than 4GB.  This leads to
problems for kexec/kdump.

Kexec reads /proc/iomem to determine the system memory layout and prepares a
memory map based on that and passes it to the kernel being kexeced.  Given the
fact that memory more than 4GB has been truncated, new kernel never gets to
see and use that memory.

Kdump also reads /proc/iomem to determine the physical memory layout of the
system and encodes this informaiton in ELF headers.  After a crash new kernel
parses these ELF headers being used by previous kernel and vmcore is prepared
accordingly.  As memory more than 4GB has been truncated, kdump never sees
that memory and never prepares ELF headers for it.  Hence vmcore is truncated
and limited to 4GB even if there is more physical memory in the system.

This patch exports memory more than 4GB through /proc/iomem on i386.

specifically be for flushing the kernel cache view of a user page which the

[PATCH] protect remove_proc_entry

It has been discovered that the remove_proc_entry has a race in the removing
of entries in the proc file system that are siblings.  There's no protection
around the traversing and removing of elements that belong in the same
subdirectory.

This subdirectory list is protected in other areas by the BKL.  So the BKL was
at first used to protect this area too, but unfortunately, remove_proc_entry
may be called with spinlocks held.  The BKL may schedule, so this was not a
solution.

The final solution was to add a new global spin lock to protect this list,
called proc_subdir_lock.  This lock now protects the list in
remove_proc_entry, and I also went around looking for other areas that this
list is modified and added this protection there too.  Care must be taken
since these locations call several functions that may also schedule.

Since I don't see any location that these functions that modify the
subdirectory list are called by interrupts, the irqsave/restore versions of
the spin lock was _not_ used.

Vivek Goyal [Sat, 25 Mar 2006 15:31:16 +0000]
[PATCH] x86_64: timer interrupt lockup due to pending interrupt

o check_timer() routine fails while second kernel is booting after a crash
  on an opetron box. Problem happens because timer vector (0x31) seems to be
  locked.

o After a system crash, it is not safe to service interrupts any more, hence
  interrupts are disabled. This leads to pending interrupts at LAPIC. LAPIC
  sends these interrupts to the CPU during early boot of second kernel. Other
  pending interrupts are discarded saying unexpected trap but timer interrupt
  is serviced and CPU does not issue an LAPIC EOI because it think this
  interrupt came from i8259 and sends ack to 8259. This leads to vector 0x31
  locking as LAPIC does not clear respective ISR and keeps on waiting for
  EOI.

o This patch issues extra EOI for the pending interrupts who have ISR set.

o Though today only timer seems to be the special case because in early
  boot it thinks interrupts are coming from i8259 and uses
  mask_and_ack_8259A() as ack handler and does not issue LAPIC EOI. But
  probably doing it in generic manner for all vectors makes sense.

When x86_64 timer init messages were changed to use apic verbosity
levels, two messages were missed and one got the wrong level.  This
causes the last word of a suppressed message to print on a line by
itself.  Fix that so either the entire message prints or none of it
does.

[PATCH] x86_64: Quieten down microcode update driver

Only log data in microcode driver when something is changed Otherwise it
was far too noisy on large systems.

Also remove the printk when it is unloaded.

14 years ago[PATCH] x86_64: Basic reorder infrastructure
Arjan van de Ven [Sat, 25 Mar 2006 15:30:49 +0000]
[PATCH] x86_64: Basic reorder infrastructure

This patch puts the infrastructure in place to allow for a reordering of
functions based inside the vmlinux. The general idea is that it is possible
to put all "common" functions into the first 2Mb of the code, so that they
are covered by one TLB entry. This as opposed to the current situation where
a typical vmlinux covers about 3.5Mb (on x86-64) and thus 2 TLB entries.

This is done by enabling the -ffunction-sections flag in gcc, which puts
each function in its own ELF section, so that the linker can then order them
in a way defined by the linker script.

As per previous discussions, Linus said he wanted a "static" list for this,
eg a list provided by the kernel tarbal, so that most people have the same
ordering at least. A script is provided to create this list based on
readprofile(1) output. The included list is provisional, and entirely biased
on my own testbox and me running a few kernel compiles and some other
things.

I think that to get to a better list we need to invite people to submit
their own profiles, and somehow add those all up and base the final list on
that. I'm willing to do that effort if this is ends up being the prefered
approach. Such an effort probably needs to be repeated like once a year or
so to adopt to the changing nature of the kernel.

Made it a CONFIG with default n because it increases link times
dramatically.

[PATCH] x86_64: Always use IO-APIC routing for timer.

I tested it on a couple of chipsets and it worked everywhere so it
should be ok as default for now.

So far I haven't done the great purge of the useless old check_timer
code yet though.

Can be overwritten with enable_8254_timer in the worst case

There is a fallback logic, so it's better to not use the OOM killer
in the allocations.
