[PATCH] 2TB files: change type of kstatfs entries

This fix was proposed by Trond Myklebust.  He says: The type "sector_t" is
heavily tied in to the block layer interface as an offset/handle to a block,
and is subject to a supposedly block-specific configuration option:
CONFIG_LBD.  Despite this, it is used in struct kstatfs to save a couple of
bytes on the stack whenever we call the filesystems' ->statfs().

So kstatfs's entries related to blocks are invalid on statfs64 for a network
filesystem which has more than 2^32-1 blocks when CONFIG_LBD is disabled.

- struct kstatfs
  Change the type of following entries from sector_t to u64.
  f_blocks
  f_bfree
  f_bavail

Takashi Sato [Sun, 26 Mar 2006 09:37:51 +0000 (01:37 -0800)]
[PATCH] 2TB files: st_blocks is invalid when calling stat64

This patch series fixes the following problems on 32 bits architecture.

o stat64 returns the lower 32 bits of blocks, although userland st_blocks
  has 64 bits, because i_blocks has only 32 bits.  The ioctl with FIOQSIZE has
  the same problem.

o As Dave Kleikamp said, making >2TB file on JFS results in writing an
  invalid block number to disk inode.  The cause is the same as above too.

o In generic quota code dquot_transfer(), the file usage is calculated from
  i_blocks via inode_get_bytes().  If the file is over 2TB, the change of
  usage is less than expected.  The cause is the same as above too.

o As Trond Myklebust said, statfs64's entries related to blocks are invalid
  on statfs64 for a network filesystem which has more than 2^32-1 blocks with
  CONFIG_LBD disabled.  [PATCH 3/3]

We made patches to fix problems that occur when handling a large filesystem
and a large file.  It was discussed on the mails titled "stat64 for over 2TB
file returned invalid st_blocks".

[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).

[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.

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.

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

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

[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.

However, nothing has flushed the kernel cache view of the page before the
kunmap.  We need a lightweight API to do this, so this new API would
specifically be for flushing the kernel cache view of a user page which the

flush_kernel_dcache_page(page) before the final kunmap.

James Bottomley [Sun, 26 Mar 2006 09:36:57 +0000 (01:36 -0800)]
[PATCH] Add API for flushing Anon pages

Currently, get_user_pages() returns fully coherent pages to the kernel for
anything other than anonymous pages.  This is a problem for things like
fuse and the SCSI generic ioctl SG_IO which can potentially wish to do DMA
to anonymous pages passed in by users.

The fix is to add a new memory management API: flush_anon_page() which
is used in get_user_pages() to make anonymous pages coherent.

Steven Rostedt [Sun, 26 Mar 2006 09:36:55 +0000 (01:36 -0800)]
[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.

[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.
