Jeff Dike authored
Changes since first version added check for MADV_REMOVE support on the host fixed error return botch shrunk sprintf array by one character This adds hotplug memory support to UML. The mconsole syntax is config mem=[+-]n[KMG] In other words, add or subtract some number of kilobytes, megabytes, or gigabytes. Unplugged pages are allocated and then madvise(MADV_TRUNCATE), which is a currently experimental madvise extension. These pages are tracked so they can be plugged back in later if the admin decides to give them back. The first page to be unplugged is used to keep track of about 4M of other pages. A list_head is the first thing on this page. The rest is filled with addresses of other unplugged pages. This first page is not madvised, obviously. When this page is filled, the next page is used in a similar way and linked onto a list with the first page. Etc. This whole process reverses when pages are plugged back in. When a tracking page no longer tracks any unplugged pages, then it is next in line for plugging, which is done by freeing pages back to the kernel. Signed-off-by:

Porting the patch I posted for x86_64 to i386. http://marc.theaimsgroup.com/?l=linux-kernel&m=114178139610707&w=2 o While using kdump, after a system crash when second kernel boots, timer vector gets (0x31) locked and CPU does not see timer interrupts travelling from IOAPIC to APIC. Currently it does not lead to boot failure in second kernel as timer interrupts continues to come as ExtInt through LAPIC directly, but fixing it is good in case some boards do not support the other mode. 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. Signed-off-by:

for_each_cpu() actually iterates across all possible CPUs. We've had mistakes in the past where people were using for_each_cpu() where they should have been iterating across only online or present CPUs. This is inefficient and possibly buggy. We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the future. This patch replaces for_each_cpu with for_each_possible_cpu. Signed-off-by:

git-commit: d5d4b0aa "[PATCH] optimize follow_hugetlb_page" breaks mlock on hugepage areas. I mis-interpret pages argument and made get_page() unconditional. It should only get a ref count when "pages" argument is non-null. Credit goes to Adam Litke who spotted the bug. Signed-off-by:

find_trylock_page() is an odd interface in that it doesn't take a reference like the others. Now that XFS no longer uses it, and its last remaining caller actually wants an elevated refcount, opencode that callsite and schedule find_trylock_page() for removal. Signed-off-by:

Current cmdlinepart.c uses offset value 0 to specify a continuous partition. This prevents creating a second partition starting at 0. For example, I can split 4MB device using "mtdparts=id:2M,2M", but I can not do "mtdparts=id:2M@2M,2M@0" to swap mtd0 and mtd1. This patch introduces special OFFSET_CONTINUOUS value for a continuous partition and allows 0 for offset value. Also this patch replaces 0xffffffff with UINT_MAX for SIZE_REMAINING. Signed-off-by:

This adds support for the sys_splice system call. Using a pipe as a transport, it can connect to files or sockets (latter as output only). From the splice.c comments: "splice": joining two ropes together by interweaving their strands. This is the "extended pipe" functionality, where a pipe is used as an arbitrary in-memory buffer. Think of a pipe as a small kernel buffer that you can use to transfer data from one end to the other. The traditional unix read/write is extended with a "splice()" operation that transfers data buffers to or from a pipe buffer. Named by Larry McVoy, original implementation from Linus, extended by Jens to support splicing to files and fixing the initial implementation bugs. Signed-off-by:
