Introduce ccflags-y, asflags-y and ldflags-y so we soon can deprecate use of EXTRA_CFLAGS, EXTRA_AFLAGS and EXTRA_LDFLAGS. This patch does not touch any in-tree users - thats next round. Lets get this committed first and then fix the users of the soon to be deprecated variants next....

Today alpha, mips and sparc uses -Werror in almost all their Makefile - with subdir-ccflag-y it is now simpler to do so as only the top-level directories needs to be covered. Likewise if we decide to cover a full subsystem such as net/ with -Werror this is done by adding a sing...

linux的内核makefile主要用于编译整个内核源码,按照用户的需求生成各种目标文件,对于用户来说,编译内核时非常简单的,只需要几个指令就可以做到,但是对于一个驱动开发者而言,了解内核源码的编译机制是非常必要的。 make 和 makefile 需要了解的是:make是linux下的一个程序软件,makefile相当于针对make程序的配置文件,当我...
佩尔方程x*x-d*y*y=1,当d不为完全平方数时,有无数个解,并且知道一个解可以推其他解。 如果d为完全平方数时,可知佩尔方程无解。假设(x0,y0)是最小正整数解。则:xn=xn-1*x0+d*yn-1*y0yn=xn-1*y0+yn-1*x0证明只需代入。 如果忘记公式可以自己用(x0*x0... ...
