Basically, it means that something in the page tables did not map well when your faulting instruction executed.

The processor determines the type of a given memory region mainly by looking at page tables, which are maintained by the kernel.

In the new startup_32 function (also called the swapper or process 0), the page tables are initialized and memory paging is enabled.

The mapping of virtual memory to physical memory occurs through page tables, which are implemented in the underlying hardware (see Figure 1).

Page table copy means that LAHF copies the page table content in kernel mode of the operating system to a set of private page tables it has established.
页表复制指的是LAHF将操作系统内核态页表的内容复制到自己建立的一套私有页表中。
These virtual addresses are mapped to physical memory by page tables, which are maintained by the operating system kernel and consulted by the processor.
这些虚拟地址映射到物理内存页表,这是维护操作系统的内核和处理器咨询。
In the Linux memory manager, page tables keep track of the physical pages of memory that are used by a process, and they map the virtual pages to the physical pages.
在Linux内存管理器中,页表保持对进程使用的内存物理页的追踪,它们将虚拟页映射到物理页。
Kernel space is flagged in the page tables as exclusive to privileged code (ring 2 or lower), hence a page fault is triggered if user-mode programs try to touch it.
系统内核所使用的内存空间通过特权码(privileged code,2级或者更低)来标记,以防止用户模式的程序访问到内核空间而发生页面错误。
Kernel space is flagged in the page tables as exclusive to privileged code (ring 2 or lower), hence a page fault is triggered if user-mode programs try to touch it.
内核空间被标记在页表中的独家特权代码(环2或更低),因此一个页面故障被触发,如果用户模式的程序试图去触摸它。
However, for systems in which a large number of processes are running, storing page tables in high memory can be enabled to squeeze more memory out of the low memory area.
不过,对于那些在大量进程在运行的系统来说,将页表存储到高端内存中可以在低端内存区域挤出更多的内存。
In the Linux 2.4 kernel, this can be a daunting task as the page tables for every process must be traversed in order to determine whether or not the page is mapped by that process.
在Linux 2.4内核中,这是一项令人生畏的任务,因为为了确定某个页是否被某个进程映射,必须遍历每个进程的页表。
Note that as shown here, a process may have a large address space, but it is sparse, meaning that small regions (pages) of the address space refer to physical memory through the page tables.
注意这里的显示,进程可能有一个大的地址空间,但是很少见,就是说小的地址空间的区域(页面)通过页表指向物理内存。
Rows cannot be split between pages, so tables with long rows require the appropriate page size.
不能将行分割到不同的页,因此具有长行的表需要有合适的页大小。
Rather, the page size for tables is determined by the page size of the buffer pool to which the table space containing the table is assigned.
相反,表的页宽是由相应的缓冲池的页宽来确定的,这个缓冲池也就是为包含该表的表空间所指定的缓冲池。
Better performance for concurrent business queries: Because MDC tables reduce page contention and locking, this also reduces disruption to the performance of concurrent business queries.
并发的业务查询能拥有更好的性能:mdc表减少了页面争用的锁,这一点同时也有利于并发业务查询的性能。
But you do want to be able to have a single handler display a potentially wide range of tables for either a single page or a range of pages.
但是您可能希望能够通过单个处理程序来显示单个页面或一系列页面的潜在范围的广泛表。
Web pages degenerated into inaccessible, complex structures of nested tables as the primary way to control page layout.
网页变得难以理解,复杂的嵌套表结构成为控制页面布局的主要手段。
In most cases, the conversion tables or definitions between the source and the target code page have not been defined.
在大多数情况下,没有定义源和目标代码页之间的转换表或定义。
The tables are positioned relative to the container, not to the page.
表格是相对于容器而不是页面来定位的。
On the second page, all available tables for the database connection are displayed (Figure 9).
在第二页面中,所有数据库链接可用的表格被显示出来(图9)。
The template will render a page using several tables and fetch text to be rendered in a table cell from a separate file by AJAX.
模板显示一个使用几个表的页面,通过AJAX从另一个文件获取要在表单元格中显示的文本。
Depending on your database you may want to have a different page size that matches the page size of your base source tables.
取决于您的数据库,您可能想要不同的页面大小,它与您的源表页面大小一致。
These tables are the external code page conversion tables used to translate values between various code pages.
这些表是用于在不同代码页之间转换值的外部代码页转换表。
However, there cannot be more than 255 rows on a page, so tables with short rows do not utilize the whole page.
但是,一个页上的行不能超过255个,因此具有较短行的表不能利用整个页。
Customers may choose to leverage a larger page size to get more data on the page — for example, a 16 KB page size can support tables that exceed 64 GB in size.
客户可能选择利用较大的页面大小以在页面上获得更多数据——例如,16KB的页面大小可以支持容量超过64GB的表。
